2 - Documentation improvements: a getting started README, and a
3 description of some of the implementation details.
4 - Include an example filter script, lbs-filter-gpg, for encrypting
5 segment data as it is written.
6 - Add support for signed snapshot descriptor files (via the
7 --signature-filter option). Due to the checksums contained in the
8 snapshot descriptor, the signature covers the entire contents of
10 - Preview release of lbs-util.py, a Python-based program for
11 managing LBS snapshots. It currently implements a very simple
12 form of automatic segment cleaning, though this isn't much tested.
13 - Improved segment repacking support; after cleaning segments,
14 objects can be written out in different groups based on age. This
15 may help with long-term segment cleaning efficiency, but probably
19 - LOCAL DATABASE CHANGE: A checksums file is now written out along
20 with the snapshot descriptor that contains checksums of segments
21 used in a snapshot. This will allow quick integrity checks of a
22 snapshot, without needing to decompress or decrypt the segment
23 files. The local database schema was modified to store the
24 checksums for segments.
25 - Build dependence on libtar has been dropped. All necessary
26 support for writing TAR files is now directly included with the
28 - The snapshot format is now documented, at least in part. See
30 - Snapshots now include link count and inode number for files with
31 multiple hard links, so that a restore program could determine
32 which files should be hard linked on restore. The reference
33 restore.pl script does not use this.
34 - Bugfix: Print a help message instead of crashing if no files are
36 - Bugfix: File descriptors of files being backed up were closed
37 twice. In some cases this might have led to an unrelated file
38 being closed (if the file descriptor was quickly re-used).
39 - Preview of a new lbs-util command for maintaining snapshots.
40 Functionality is currently limited.
43 - Update reference restore.pl script to handle octal/hexadecimal
44 (format change introduced in 0.2).
45 - Better support for mixing multiple backup schemes: the statcache
46 file is now per-scheme, so performance should be better in cases
47 where multiple different backups (of different source directories)
48 are made, all sharing the same local database directory.
51 - Bugfix: Do not print an error when only one directory is specified
55 - SNAPSHOT FORMAT CHANGE: Metadata logs in backups can now contain
56 octal and hexadecimal values. Old restore programs may not be
57 able to read these new backups. The reference restore.pl script
58 has not yet been updated.
59 - LOCAL DATABASE CHANGE: Backups may be assigned a name with the
60 --scheme= command-line option, to allow different backup sets to
61 be mixed in the same directory. The database schema for the local
63 - Improved selection (inclusion/exclusion) of files to be included
65 - Device major/minor numbers are dumped for block and character
