snapraid (11.2-0tikhonov1) xenial; urgency=medium
[11.2 2017/12]
* Fixed recognition of NTFS hardlinks. They behave differently than
standard Unix hardlinks and this could result in SnapRAID reporting
internal inconsistency errors for detecting links to the same file
with different metadata attributes.
* More efficient 'pool' command that updates only the links
that need to be updated. This ensures that no change is
done, avoiding to trigger a directory rescan of other programs.
* In Linux use by default the advise "discard" mode instead of "flush".
This avoids to swap-out the other process memory, leaving the system
more responsive.
* Changed the fallocate() use to work better with Btrfs with parity disks.
* Changed the --test-io-stats screen to print the file name in process
for each disk.

snapraid (11.1-0tikhonov1~trusty) trusty; urgency=medium
[11.1 2017/05]
* Fixed the check command to correctly ignore errors on unused parity.
This was broken in version 9.0.
* Allow increasing the number of parity splits of existing parity.
* Fixed quoting when printing in Linux. This fixes the UTF-8 screen
output. Windows version was not affected.
* Fixed recognition of 'hashsize' in the configuration file.
The previous incorrect 'hash_size' is still supported for backward
compatibility.
* Fixed building in platforms that don't provide major/minor definitions
in sys/types.h.
* When creating 'pool' symbolic links, set their time as the linked files.
* Added support for the Windows 10 symbolic link unprivileged creation,
using SYMBOLIC_LINK_FLAG_ALLOW_UNPRIVILEGED_CREATE.
* Windows binaries built with gcc 4.9.4 using the MXE cross compiler at
commit ae56efa2b23a793b0146508bfef33027cdb09fd2 with targets
i686-w64-mingw32 and x86_64-w64-mingw32 and optimization -O2.

snapraid (11.0-0tikhonov1~trusty) trusty; urgency=medium
[11.0 2016/11]
* Added support for splitting the parity in multiple partitions. You
can now specify multiple files for a single parity. As soon a file
cannot grow anymore, the next one starts growing.
In the configuration file, just put more files in the same 'parity'
line, separated by , (comma).
Note that if this feature is used, the saved content file won't be
read by older SnapRAID versions.
In Windows, 256 MB are left free in each disk to avoid the warning
about full disks.
* Added a new 'hashsize' configuration option. It could be useful in
systems with low memory, to reduce the memory usage.
Note that if this feature is used, the saved content file won't be
read by older SnapRAID versions.
* In Linux added the missing support for Btrfs file-systems. Note that
to have full support you need also the 'libblkid' library, otherwise
you won't get the UUIDs.
* In screen messages don't print the disk directory in file path. You
can control the format with the test option:
--test-fmt file|disk|path.
* In Windows allows to use the escape char '^' to handle file patterns
containing real characters matching the globbing '*?[]' ones. In Unix
it was already possible to do the same escaping with '\'.
* Added a new -R, --force-realloc option to reallocate all the
parity information keeping the precomputed hash.
This is the previous -F, --force-full that instead now maintains the
same parity organization and just recomputes it.
* Added test options for selecting the file advise mode to use:
--test-io-advise-none for standard mode
--test-io-advise-sequential advise sequential access (Linux/Windows)
--test-io-advise-flush flush cache after every operation (Linux)
--test-io-advise-flush-window flush cache every 8 MB (Linux)
--test-io-advise-discard discard cache after every operation (Linux)
--test-io-advise-discard-window discard cache every 8 MB (Linux)
--test-io-advise-direct use direct/unbuffered mode (Linux/Windows)
The new default mode is 'flush' in Linux (before it was 'sequential'),
and 'sequential' in Windows (like before).
* For Seagate SMR (Shingled Magnetic Recording) ignore the SMART
attribute Command_Timeout 188 as not reliable.
* Fixed running in Windows platforms that miss the RtlGenRandom()
function.
* Added the --test-io-cache=1 option to disable the multi-thread IO
mode.

snapraid (10.0-0tikhonov1~trusty) trusty; urgency=medium
[ 10.0 2016/02 ]
* Boosts the speed of the 'sync' and 'scrub' commands with a new
multi-thread implementation. It uses one thread for each disk,
dedicated exclusively to read-ahead data and parity and to
write-behind parity. This maximizes the data throughput keeping
disks always busy.
You can control the number of blocks to cache with the option
--test-io-cache=NUMBER, where the number is between 3 and 128.
The default is 8 MiB of blocks.
You can show run-time stats during the process with the
--test-io-stats option. You will see a graph with the number of
cached blocks, and a graph with the wait time percentage for all the
disks and computations.
* The -h, --pre-hash command, saves the content file only after having
verified all the hashes. This allows recovering of moved files in
case a silent error is found during the hash verification check.
* Allows to use the -d, --filter-disk option in the 'up' and 'down'
commands.
* Allows to run the 'smart' command without a configuration file.
In such case it operates on all the disks of the machine.
* In the configuration file 'data' is now a synonymous of 'disk'.
* Adds the 'touch' command intended to arbitrarily set all the zero
sub-second timestamps. This improves the SnapRAID capabilities to
identify files. The 'status' command recommends to run 'touch' if
required.
* Restores the functionality of the -D, --force-device option when used
to workaround the use of the same disk for two logical data drives
when running the 'fix' command.
* Uses a correct shell quoting in the example commands that involve
files.
* The minimum Windows version supported is now Windows Vista. This is
required to use the native Windows thread support for the new
multi-thread implementation. If you need to run on Windows XP, you
have to stick on SnapRAID 9.x.

snapraid (9.3-0tikhonov1~trusty) trusty; urgency=medium
[ 9.3 2016/01 ]
* Fixes an invalid assumption in the copy detection mechanism that
could result in an internal inconsistency, and with the impossibility
to run the 'sync' and 'diff' commands.
This was triggered by a very specific pattern of identical files.
At least three of them, with one already in the parity, and at a
higher disk number than the others that should be instead new ones.
This had no bad effect, if not preventing the 'sync' command to run.
A workaround was to just run 'sync' one time with the -N,
--force-nocopy option to disable the copy detection.
* Restored the -O2 optimization option for Windows binaries, as -Og has
a too big performance penality.
[ 9.2 2016/01 ]
* Fixes support for symlinks pointing to an empty target. Before they
were only partially supported, and their presence could result in a
content file not readable.
This also disables multi-thread content write, as this was the issue
we tried to detect with this feature, and it doesn't provide a
performance advantage. Content verification is instead still multi
thread.
* Autorename disks using the matching UUID. To rename a disk you can
now change directly the name in the configuration file, and run a
'sync' command.
* Improves the physical offset ordering for the Btrfs file-system,
correctly detecting files that have not a physical offset, for
whatever reason.
* Adds UUID support to Btrfs file-systems. It's present only if the
'libblkid' development library is available on the system.
Usually this requires to install the libblkid-dev or libblkid-devel
package.
* Added a new --no-warnings option to disable some repetitive warnings
that could be annoying to power users.
* Improves the error reporting, printing a complete stack trace, that
can be used to track down bugs more easily.
For this reason the Windows binaries are now built with optimization
option -Og, instead than -O2.

snapraid (9.1-0tikhonov1~trusty) trusty; urgency=medium
[ 9.1 2015/11 ]
* Fixes a bug when reading a content file with a deleted entry bigger
than 4 GB. This was a regression introduced in version 9.0 that
could result in the impossibility to read a valid content file,
after a deletion of a file bigger than 4 GB in the array.
If this happened to you, just upgrading to 9.1 fixes the issue, and
it allows you to continue to work.
Note that this bug only prevented to run 9.0, but your data was still
protected and could have been recovered using the versions 8.1 or 9.1.
* In Windows disables the file zero check requiring the --force-zero
option. This check is intended for possible case using ext3/4 in Linux,
and there is no evidence that in Windows it's possible at all.
* Windows binaries built with gcc 4.9.3 using the MXE cross compiler at
commit 62bcdbee56e87c81f1faa105b8777a5879d4e2e with targets
i686-w64-mingw32 and x86_64-w64-mingw32 and optimization -O2.
[ 9.0 2015/11 ]
* Fixes an invalid assumption that could happen when using the
-e, --filter-error option with "fix" or "check".
This was triggered by a very specific pattern of fragmented files
and bad blocks combination, not so easy to reproduce.
This had no bad effect, if not preventing the command to run.
* Drastically reduces the memory usage. For each block, it now
uses 17 bytes of memory, instead of the previous 28 bytes
(for 32 bit) or 36 bytes (for 64 bit).
This could result is a memory saving of up the 50%.
* The -p, --plan option (old --percentage) can be used to
define a scrub plan: "new", "bad" and "full".
The "new" plan scrubs all the new synced blocks not yet scrubbed.
This allows to verify as early as possible that the written
parity during sync is really correct. You can use the "status"
command to show the amount blocks not yet scrubbed.
The "bad" plan scrubs only bad blocks.
The "full" plan scrubs all blocks.
* The graph in the "status" command now show scrubbed blocks
with '*', and synced, but not yet scrubbed, blocks with 'o'.
Note that when upgrading from a previous version, all blocks
are assumed scrubbed the first time.
* Content files are now written asyncronously from different
threads to avoid the unfortunate condition that a memory
error affects all of them in the same way.
After writing, they are read again to verify their CRC.
This is done to ensure thay they are really OK, even in the
case of the worst possible silent errors.
* Extends the -D, --force-device option to ignore more
erroneous conditions in the 'fix' command, like unaccessible
disks, or disks sharing the same physical device.
* Extends the -d, --filter-disk option to allow to filter also
by parity disk.
* Extends the -h, --pre-hash option to also verify moved and
copied files into the array before running a 'sync'.
* Updates 'best' RAID functions for recent Atom CPUs.
* Validates filters specifications rejecting relative paths.

snapraid (8.1-0tikhonov1~trusty) trusty; urgency=medium
[ 8.1 2015/05 ]
* Fix build issues in generic Unix platforms, including Mac OS X.
* The "diff" command returns with error code 2 if a "sync" is
required, to differentiate with the generic error code 1.
* Reduced the effect of SMART attribute 193 on the failure
probability to avoid some false positive reports.

snapraid (8.0-0tikhonov1~trusty) trusty; urgency=medium
[ 8.0 2015/04 ]
* Allows "sync" and "scrub" to continue after the first bunch of disk
errors. Blocks with errors are marked as bad, and you can fix them
with the "fix -e" command.
The fix is expected to force the disk firmware to reallocate the
bad sector, likely fixing the problem.
You can control the number of allowed errors with the new
-L, --error-limit option. The default is 100.
* The -e, --filter-error option doesn't write anymore fixes to
unsynced files. This helps in case you are running it on a not
synced array, removing the risk to revert some files to an old state.
* The -e, --filter-error option is now optimal and reads only the
minimal amount of data necessary to fix the errors.
* The "diff" command returns with an error code if a "sync" is
required.
* Adds new "smart" command to print a SMART report of the array.
* Adds new "up" and "down" commands to spin up and down the disks of
the array.
* Adds new "devices" command to print the devices associations in
the array.
* Changes the log handling. If no log file is specified, all the
warnings and not fatal errors messages goes to stderr. If a log file
is specified, only fatal error messages are printed on the screen.
You can control the amount of informative messages on stdout with
the -q, --quiet and -v, --verbose options, that can be specified
multiple times to be more quiet or verbose.
* In the "status" command the "Wasted" column now shows a negative
number for the amount of space that you can still waste without
filling up the parity.
* In the "status" and others commands we now use GB instead of GiB,
when referring to disk space.
* Renames the -s and -t options to -S and -B as they are intended to
be manual only operations.
* Windows binary built with gcc 4.8.1 using the MXE cross compiler 2.23,
with targets i686-w64-mingw32 and x86_64-w64-mingw32. Before the x86
target was i686-pc-mingw32.

[ 7.1 2015/01 ]
* In 'scrub' and 'sync' detects and reports Input/Output errors
separately from generic file system errors.
* In 'diff' doesn't print the "add" entry if a "copy" one is already
printed.
* Fixes build with old compilers in the x64 platforms [Leigh Phillips].

snapraid (7.0-0tikhonov2~precise) precise; urgency=medium
[ 7.0 2014/11 ]
* In 'check' and 'fix' the array is scanned to find any moved files
that could be used to recover missing data. Files are identified by
timestamp, and then they are recognized also if moved to a different
disk. Note that even if there are false positive they are identified
checking the hash, so they have not effect, besides making the
process a little slower. To disable this new behaviour you can use
the -N, --force-nocopy option.
* The -i, --import command now identifies files by timestamp making it
very fast in importing directories.
* More detailed 'status' report with single disk stats and free space
available.
* A lot faster directory listing for Windows.
* Adds AVX2 support to improve parity generation speed.
* Prints the time spent waiting for each disk also in 'scrub'.
* The CPU usage, speed and ETA estimations are now based on the last 100
seconds rather than from the start.
* Keeps track of the UUID of the parity disks to check them before
operating.
* Windows binary built with gcc 4.8.1 using the MXE cross compiler 2.23.

snapraid (6.2-0tikhonov1~precise) precise; urgency=low
[ 6.2 2014/5 ]
* Fixed the regression test when run as root.
* Added a new heuristic to detect file copies. Now a file is assumed
to be a copy if name, size and nanosecond timestamp are matching,
but if the nanosecond part of the timestamp is 0, it requires
the full path matching and not only the name.
* Added the -N, --force-nocopy option to disable completely
the copy detection. SnapRAID also suggests to use this option
in the error message of a data mismatch if likely caused by the
copy detection.

snapraid (6.0-0tikhonov1~precise) precise; urgency=low
[ 6.0 2014/3 ]
* In "sync", even if a silent error is found, continue to update
the parity if it's possible to correct the error.
Note that the block will be marked bad, and the data
will be fixed only at the next "fix -e" call.
But any new data added will be protected if you are using
enough parity to fix both the silent error and at least
another potential error.
* Detect copied files from one disk to another and reuse the already
computed hash information to validate them in "sync".
Files are assumed copied if they matches the name, size and timestamp.
* For "sync", added a new -h, --pre-hash option to run a preliminary
hashing step for all the new files to ensure to detect silent errors
caused by the heavy machine usage of the parity computation.
* In "fix", if a previous fixing attempt was made resulting in a
.unrecoverable file, uses this file as starting point for the
new attempt.
* In the log file name allows the use of the '>>', %D, %T modifiers
to select append mode, and to insert the date and time in the name.
* The options -p, --percentage and -o, --older-than now keep their
default value even if the other one is specified.
* Moved the .lock file in the same dir of the first specified content
file. This avoid to spin-up the parity disks in all commands.
* The "diff", "list", "dup", "status" and "pool" commands don't access
anymore the parity disks that can now stay powered down.
* The default configuration file in Windows is now searched in the same
directory where the snapraid.exe file resides.
* New source code organization. The RAID engine is now
an external component usable also in other projects.

snapraid (5.3-0tikhonov1~precise) precise; urgency=low
[ 5.3 2014/3 ]
* Don't warn about UUID changed if it's for an empty disk.
* Fixed the number of blocks that scrub has to process when
selecting a high percentage of the array.
* Removed duplicate recovery attempts in synced state.
[ 5.2 2013/12 ]
* If a disk changes UUID, automatically disable the inode
recognition, because this is likely a new filesystem with
all the inodes reassigned, and we don't want to risk a false
positive when searching for inode/timestamp/size.
* Allow to run a fix command with disks that doesn't need to be
fixed mounted as read-only.
* After a failed sync, always reallocates new files with a not
yet computed parity to ensure to minimize the parity usage,
if some other file is deleted in the meantime.
* Doesn't count empty dirs as files in the diff counters.
* Added a new "share" configuration option to allow to share
in the network the pool directory also in Windows.
* Fixed build problems in OpenBSD due the old assembler.
* Fixed build problems in platforms different than x86.
[ 5.1 2013/12 ]
* Fixed a potential crash if a file is deleted during a "sync/scrub".
This is a problem introduced in version 5.0 due new logging.
If happened to you to have a crash in sync, you don't need to
take any special action, just run "sync" again.
* Restored the functionality of -C, --gen-conf command.
* Prints the files with duplicate physical offset if the
-v, --verbose option is specified.

snapraid (5.0-0tikhonov1~precise) precise; urgency=low
* New upstream release.
[ Upstream changelog 4.4 ]
* Added support for up to six levels of parity.
* Added a specific and faster triple parity format for CPUs that
don't support SSSE3 instructions like ARM and AMD Phenom, Athlon
and Opteron.
* Faster RAID5 and RAID6 implementation for ARM 64 bit CPUs.
* If a silent error is found during a "sync" command, directly marks
the block as bad like in "scrub", without stopping the the "sync"
process.
* Sort files by inode when listing the directory. This improves
the scanning performance.
* For files with changes only in some blocks, updates the parity
only for blocks that really are changed.
This improves the performance in sync for modified files.
* Added a new "list" command to see the stored list of files.
* Removed the detailed list of errors from the screen output.
To get it you must explicitely use the -l, --log option.
It's now too detailed for the screen, because it contains a lot
of info.
* Changed the output format of some commands to make it similar
at the new "list" one.
* Reduced memory usage removing some unnecessary allocations.
* Added a memory test on the memory buffers used in sync/scrub/check/fix
before using them.

snapraid (4.4-0tikhonov1~precise) precise; urgency=low
* New upstream release.
[ Upstream changelog 4.4 ]
* Relaxed the check about small parity files, to allow to recover after a
failed sync before resizing the parity files.
[ Upstream changelog 4.3 ]
* Fixed the scrub command with the -p0 option. Now it really scrubs only the
blocks marked as bad and not the full array.
[ Upstream changelog 4.2 ]
* Fixed the wrong warning about physical offsets not supported caused by files
not having a real offset because too small. For example, in NTFS it's possible
to store such files in the MFT. It's just a cosmetic change, and not a
functional one.
* Remove unexpected 'Restore' entries in the diff output when dealing with
filesystem without persistent inodes like NTFS in Linux.
* Added support for filenames containing newlines. This happens in Mac OS X.
[ Upstream changelog 4.1 ]
* If the underline filesystem doesn't support the FIEMAP command, automatically
fallback to use FIBMAP for sorting files.
* Fixed the import of content files from previous version of SnapRAID that are
the result of an incomplete sync.
* Added a new -C, --gen-conf option to generate a dummy configuration file from
the info in the content file. Just in case that you lose everything, except
the content file.
* At the end of sync/scrub/check/fix prints "Everything OK" if no error was found.
This should make clear that everything is really OK.
[ Upstream changelog 4.0 ]
* New 'scrub' command to periodically check the oldest blocks for silent
errors without the need to scan the whole array.
* New 'status' command to check the fragmentation, the last check time
distribution, and the silent error status of the array.
* Added the new Spooky hash. It's faster in 64 bit architectures. To
convert you can use the new 'rehash' command.
* Changed to a binary content file to improve speed and reduce size.
* Removed the --find-by-name, -N option. Now it always searches
by name if a file is not found searching by inode, automatically
reassigning inodes in restored files without needing to sync
again the file. This happens only if the file has the same path, size
and timestamp at nanosecond precision.
* Added a hash seed to make harder intentional collision attacks.
* When inserting files for the first time, sort them by their physical
address to improve read performance.
* Optimized the cache use for the all the RAID computations.
This improves a lot the RAID performance.
* Better selection of the RAID6 implementation for different CPUs.
* Added RAID5/RAID6 mmx and sse2 implementations with unrolling by 4.
They are a little faster than the previous unroll by 2.
* Added a lock file to avoid multiple running instances on the same array.
The file is named as parity file adding the .lock extension.
There is also the undocumented --test-skip-lock to avoid to check it.
* Automatically ignores, with warning, mount points inside the array
directory tree.
* Changes the 'dup' output format to include the size of each duplicate file.

* New upstream release.
[ Upstream changelog 3.2 ]
* Fix a directory creation problem in Windows when the "disk" option points to
the root directory of a drive. Now SnapRAID won't complain about the
inability to create such directory.
If you encouter this problem when trying to recover your data, just upgrade
to this version, and you'll be able to complete the recovering process.
No need to upgrade for platforms different than Windows.
[ Upstream changelog 3.1 ]
* Direct use of Windows API for disk access to improve error reporting.
* If the 'fix' process is aborted, it removes all the new files partially
recovered, to allow to reuse again the '-m, --filter-missing' flag.
* In Windows don't exclude anymore system files. Only system directories are
excluded.
* In Windows applies filters in case insensitive way.
* The Windows binaries are now built with gcc 4.7.2.
* Reduced memory occupation for hardlinks and directories.
* In 'dup' don't list file with 0 size.

* New upstream release.
[ Upstream changelog ]
* Added pooling support with the new 'pool' command. It creates a virtual
view of the array using symbolic links pointing to the original files.
* Added a new -m, --filter-missing option that allow to undelete files,
without checking/fixing the others.
* Added a new -i, --import option to automatically import deleted files
when fixing.
* Added a new -l, --log option to save to disk the detailed log.
* Added support also for hardlinks and empty directories.
* Added support to save symlinks to files in Windows. Note that only the
symlink is saved and not the linked file.
Symlinks to dirs and junctions are still not supported in Windows.
* Files without read permission generate an error instead of a warning.
You now must explicitely exclude them in the configuration file with
exclusion rules.
* In 'check' and 'fix', if verbose is enabled, prints the result for each
processed file.
* Added an UUID check to detect when a disk is replaced, and to prevent

snapraid (2.0-0tikhonov1~precise) precise; urgency=low
* New upstream release.
[ Upstream changelog ]
* Added a new -a option to make the 'check' command to only check file hashes
without checking the parity data.
* Added a new -d option to filter by disk name.
* The file modification time is now saved using nanosecond precision.
This allows to restore the exact modification time in 'fix'.
The new 'content' files written with this version are not backward
compatible, but it's still possible to read the old 'content' format.
* Fixed hard-links automatic exclusion. All the hardlinks after the first one
are now correctly ignored.
* If it isn't possible to grow a parity file, prints the list of files
outside the maximum size allocated.
* Autosave isn't triggered if we are near the end of the 'sync' process.
* Before starting a 'sync', we wait for two seconds, to workaround the FAT
limitation of having two seconds modification time precision.
This a safe measure to be 100% sure to always detect file changes.
* Always fill the memory after allocating it to avoid the OOM (Out Of Memory)
killer in Linux.
* Fixed compilation in Solaris/OpenIndiana for lacking both futimes()
and futimens().
* Now 'sync' ensures that the parity files are not too small to contain the
just loaded data.
* Removed the '-H,--filter-nohidden' option. It doesn't make sense to
have it as command line option.
You must use the 'nohidden' option in the configuration file.
* When opening files in read-only mode, also specify the noatime flag,
to avoid to update the file access time.
* Exclude rules for files are now also applied to directories.
This allows to excludes some file/directory without the need to call
the stat() function on them.
* The -N, --find-by-name option also ignores the nanosecond part of
timestamps to work with copy programs not supporting nanoseconds.
* Fixed deduplicated files handling in Windows Server 2012.
* Removed MD5 support.

snapraid (1.13-0tikhonov1~precise) precise; urgency=low

[ Upstream changelog ]
* Fixed a Segmentation Fault when checking/fixing if there are three or
more errors in a specific block.

snapraid (1.12-0tikhonov1~precise) precise; urgency=low
* New upstream release 1.12.
[ Upstream changelog ]
* Fixed file renaming in Windows during a 'fix' command. This is only a
Windows issue, no reason to upgrade for other platforms.

snapraid (1.11-0tikhonov1~precise) precise; urgency=high
* New upstream release 1.11.
[ Upstream changelog ]
* Fixed again directories inclusion. Exclusion rules for directories were ignored.

snapraid (1.10-0tikhonov1~precise) precise; urgency=low
* New upstream release 1.10.
[ Upstream changelog ]
* Fixed directory inclusion, in case the last rule is an "include" one.
* Fixed very long paths in Windows. We now always use the special '\\?' prefix to remove the 260 chars limitation.
* If a file is excluded, it prints explicitely which attribute caused the exclusion.
* Automatically excludes also the temporary copy of content file, the one with the ".tmp" extension.
* Avoid the Windows system to go in automatic sleep mode when running.
-- Maxim Tikhonov <flaterichd@gmail.com> Sun, 01 Jul 2012 21:43:16 +0400
snapraid (1.9-0tikhonov1~precise) precise; urgency=low
* New upstream release 1.9.
[ Upstream changelog ]
* Implemented a more sophisticated recovering in case a harddisk failure happens during a 'sync'
command. When using RAID6 it improves the chances of recovering data after an aborted 'sync'.
* Fixed the count of new files.
* Added a new 'autosave' configuration option to save the intermediate 'sync' state.
* Supported filesystems with read requests returning less data than requested.
* In Windows ensures that the disk serial number is not zero.
-- Maxim Tikhonov <flaterichd@gmail.com> Tue, 10 Apr 2012 17:31:51 +0400
snapraid (1.8-0tikhonov1~oneiric) oneiric; urgency=low
* New upstream release 1.8.
Upstream changelog:
* Added a new "dup" command to find all the duplicate files.
* Added a new option "--filter-nohidden" to exclude hidden files.
* Faster and parallel writing of content files.
* The example configuration files now put the content files in the data
disks instead than in the parity disks.
* Added a checksum at the content file to ensure its integrity.
* Using fallocate() instead posix_fallocate() to avoid the very slow
posix_fallocate() fallback of writing the whole file.

snapraid (1.7-0tikhonov2~oneiric) oneiric; urgency=low
* Fixed example snapraid.conf.

Description: SnapRAID is a backup program for disk arrays.
SnapRAID is a backup program for disk arrays.
.
SnapRAID stores redundancy information in the disk array, and it allows recovering from up to two disk failures.
.
SnapRAID is mainly targeted for a home media center, where you have a lot of big files that rarely change.
.
Beside the ability to recover from disk failures, the other features of SnapRAID are:
- You can start using SnapRAID with already filled disks.
- The disks of the array can have different sizes.
- You can add more disks at any time.
- If you accidentally delete some files in a disk, you can recover them.
- If more than two disks fail, you lose the data only on the failed disks. All the data in the other disks is safe.
- It doesn't lock-in your data. You can stop using SnapRAID at any time without the need to reformat or move data.
- All your data is hashed to ensure data integrity and avoid silent corruption.
