-0.7 [??]
+0.9 [2009-07-28]
+ - Rework storage layer, to make it easier to support local files,
+ S3, and in the future more storage backends. cumulus-util now
+ permits URLS for specifying storage locations, including s3:// for
+ Amazon S3 storage.
+ - The script-level interface between the main cumulus binary and
+ remote storage has changed. It should not yet be considered
+ completely finalized.
+ - Add a tool (cumulus-sync) for copying snapshots between storage
+ repositories.
+ - Add a (mostly proof-of-concept) FUSE interface for accessing
+ snapshots.
+ - Implement a basic garbage-collection command for deleting unused
+ segments. There still needs to be a way to select snapshots to
+ delete (perhaps based on some type of schedule).
+ - Assorted minor bugfixes.
+
+0.8 [2008-08-01]
+ - SNAPSHOT FORMAT CHANGE: The snapshot format has been extended to
+ allow the local database to be partially rebuilt from the contents
+ of the metadata log. This may be useful for disaster recovery and
+ other scenarios. The changes are small, but old tools will not
+ read the new backups.
+ - Add the --rebuild-statcache option which will re-read all files
+ instead of depending on the statcache file to be correct. This
+ will additionally print warnings if a file has changed but would
+ not have been detected as changed based on the statcache, and will
+ add subfile incremental signatures for existing files that do not
+ have them.
+
+0.7 [2008-06-23]
+ - LOCAL DATABASE CHANGE: The addition of subfile incrementals has
+ requires an extension to the local database. The upgrade script
+ contrib/upgrade0.7-localdb.sql should be run prior to running
+ backups with this version.
+ - Name change: the system is now known as Cumulus (replacing the old
+ name of "LBS"). Some traces of the old name still remain.
- Initial support for direct backups to remote storage. A sample
script is provided for backing up to Amazon S3. Other scripts
- should be simple to write.
+ should be simple to write. The interface should not yet be
+ considered stable, and may change in a future release.
+ - Support for efficient subfile incremental backups. Changes to a
+ small portion of a file do not require re-uploading substantially
+ all of the file, even in cases where there is an insertion or
+ deletion that shifts most of the file contents.
- Allow selected files/directories to be restored, not simply an
entire snapshot. Additionally, restore files in an order that
should optimize performance (restore files based on how they are
grouped into segments, instead of lexicographic order).
+ Currently, the implementation of these changes requires that all
+ metadata be loaded into memory when the restore tool runs, so it
+ is more memory-intensive than the old version. This may be fixed
+ in a future version; in the meantime, if the current restore tool
+ requires too much memory, try the old restore tool or the
+ restore.pl script.
+ - Add a verbose ("-v") flag. By default, files will not be listed
+ as they are backed up. The old behavior can be turned back on
+ with -v.
