Update to 0.28.1 Upstream changes: * The index format has changed, which will trigger a full index rebuild on the next index run, making that run more expensive than usual. * When given `--xdev`, `bup save` should no longer skip directories that are explicitly listed on the command line when the directory is both on a separate filesystem, and a subtree of another path listed on the command line. Previously `bup save --xdev / /usr` could skip "/usr" if it was on a separate filesystem from "/". * Tags along a branch are no longer shown in the branch's directory in the virtual filesystem (VFS). i.e. given `bup tag special /foo/latest`, "/foo/special" will no longer be visible via `bup ls`, `bup web`, `bup fuse`, etc., but the tag will still be available as "/.tag/special". * bup now provides experimental `rm` and `gc` subcommands, which should allow branches and saves to be deleted, and their storage space reclaimed (assuming nothing else refers to the relevant data). For the moment, these commands require an `--unsafe` argument and should be treated accordingly. Although if an attempt to `join` or `restore` the data you still care about after a `gc` succeeds, that's a fairly encouraging sign that the commands worked correctly. (The `t/compare-trees` command in the source tree can be used to help test before/after results.) Note that the current `gc` command is probabilistic, which means it may not remove *all* of the obsolete data from the repository, but also means that the command should be fairly efficient, even for large repositories. * bup may have less impact on the filesystem cache. It now attempts to leave the cache roughly the way it found it when running a `save` or `split`. * A specific Python can be specified at `./configure` time via PYTHON, i.e. `PYTHON=/some/python ./configure`, and that Python will be embedded in all of the relevant scripts as an explicit "#!/..." line during `make install`. * The way bup writes the data to disk (the packfiles in particular), should be a bit safer now if there is a coincident power failure or system crash. * bup should be more likely to get the data to permanent storage safely on OS X, which appears to follow a surprising interpretation of the `fsync()` specification. * The build system now creates and uses cmd/bup-python which refers to the `./configure` selected python.

Update to 0.27: This version primarily fixes bugs, but it includes a few new features, and hopefully will provide a solid base for 0.28, which may finally include rm/gc support. Of note since 0.26: - Files can be restored sparsely via "restore --sparse". See bup-sparse(1) for the details. Given that this option is completely new and affects the data written, some caution/verification may be wise (i.e. there were bugs in some of the development revisions that could mangle the output). - Duplicity backups can be imported via the *experimental* command "bup import-duplicity". Please exercise caution, and let us know if you have any trouble. - Tests can be run in parallel now via "make -j check". As before, the metadata support is somewhat immature, but it seems to be holding up fairly well. Though we still need to add better support for cross-filesystem-type save/restore (which can be too noisy), etc.

Update to 0.26: This release doesn't include anything as significant as the metadata support added in 0.25, but it has quite a few bug fixes and internal improvements, in addition to these notable changes: - When --meta is specified to the fuse command, instead of generic data, the originally saved mode, uid, git, atime, mtime, and ctime will be reported for the archive paths. - When --browser is specified to the web command, a browser window will be opened for the repository. - The -x/--xdev/--one-filesystem options now include the mountpoint itself in the traversal (matching rsyc, tar, etc.). - Empty lines in --exclude-rx-from files will be ignored. Previously they would cause all paths to be excluded. - The index and restore commands now support --exclude-rx-from. - Relative filesystem --excludes like "--exclude bar" should now work. Previously --excludes had to be absolute. - The drecurse command now supports --exclude-rx and --exclude-rx-from. - The --compress option should now work for remote repositories. - Streams saved via "bup split" will now show up as a single file named "data" at the top level of the VFS, instead of as a subtree (i.e. when examined via ftp, ls, and fuse). - The ls command now supports -n, -A, -F, --file-type, --numeric-ids, and detailed -l options. - The save dates are now taken from the corresponding git commit's author date, not the committer date. - The tornado server, required by the web command, is no longer included. See the README for installation instructions. Note that the metadata support is still somewhat immature. For example, we still need to add better support for cross-filesystem-type save/restore (which is too noisy), etc. Please give this release a try and let us know what's broken. If you're new to bup, start with the README (and then HACKING if you'd like to help further): https://github.com/bup/bup/blob/master/README.md https://github.com/bup/bup/blob/master/HACKING http://anonscm.debian.org/gitweb/?p=users/rlb/bup.git;a=blob;f=README.md;hb=refs/heads/master http://anonscm.debian.org/gitweb/?p=users/rlb/bup.git;a=blob;f=HACKING;hb=refs/heads/master And although I probably sound like a broken record -- while we expect bup to work fairly well, I still don't recommend it as your sole backup strategy. I'd still suggest a periodic tar/rsync/etc. backstop.

Update to 0.25: This release includes a veritable ton of work, but the biggest change is probably the addition of real (YMMV) metadata support, including hardlinks, and the ability to directly save/restore trees without tar and split/join. See bup-index(1), bup-save(1), bup-restore(1), bup-meta(1), bup-xstat(1), and the updated "Using bup" section in the README. Note though, that the metadata support really is our first pass, and there are already things that we know need fixing (i.e. better support for cross-filesystem-type save/restore (too noisy), etc.). And check the "Notes on ..." sections in the README for some platform-specific limitations. An incomplete list of other notable changes since 0.24b: - bup will no longer create ~/.bup implicitly; "bup init" is required. - "bup split" now supports a compression-level option (-#). - "bup tag" now supports "-f". - "bup ls" now supports "-a", "-s", "--human-readable", etc., and reports more information. - "bup web" now supports "--human-readable". - "bup import-rdiff-backup" has been added. - "bup cat-file" has been added. - The default "/usr" installation prefix can be overridden via PREFIX. - Python 2.4 is no longer supported. And we have at least one (likely minor) known issue: - *Very* large (i.e. probably greater than MAX_LONG), or negative filesystem timestamps may not always be handled correctly at the moment. We'll fix that soon. And related -- some of the tests may fail on FUSE filesystems.

Initial import of bup-0.24b. bup is a program that backs things up. bup has a few advantages over other backup software: It uses a rolling checksum algorithm (similar to rsync) to split large files into chunks. The most useful result of this is you can backup huge virtual machine (VM) disk images, databases, and XML files incrementally, even though they're typically all in one huge file, and not use tons of disk space for multiple versions. It uses the packfile format from git (the open source version control system), so you can access the stored data even if you don't like bup's user interface. Unlike git, it writes packfiles directly (instead of having a separate garbage collection / repacking stage) so it's fast even with gratuitously huge amounts of data. bup's improved index formats also allow you to track far more filenames than git (millions) and keep track of far more objects (hundreds or thousands of gigabytes). Data is "automagically" shared between incremental backups without having to know which backup is based on which other one - even if the backups are made from two different computers that don't even know about each other. You just tell bup to back stuff up, and it saves only the minimum amount of data needed. You can back up directly to a remote bup server, without needing tons of temporary disk space on the computer being backed up. And if your backup is interrupted halfway through, the next run will pick up where you left off. And it's easy to set up a bup server: just install bup on any machine where you have ssh access. Bup can use "par2" redundancy to recover corrupted backups even if your disk has undetected bad sectors. Even when a backup is incremental, you don't have to worry about restoring the full backup, then each of the incrementals in turn; an incremental backup acts as if it's a full backup, it just takes less disk space. You can mount your bup repository as a FUSE filesystem and access the content that way, and even export it over Samba.
