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