/bup, Highly efficient file backup system based on the git packfile format
0.28.1, Package name:
bup-0.28.1, Maintainer: gdt
bup is a program that backs things up. bup has a few advantages over other
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
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
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.

Remove unnecessary REPLACE_PYTHON lines and patch.
Add perl to run-time depends, at least one subcommand uses it.
(should perhaps be replaced, it's just for stat())
Fix path to REPLACE_PERL files.
Add rsync to BUILD_DEPENDS, it's needed for some tests.

Update to 0.28.1
* The index format has changed, which will trigger a full index
rebuild on the next index run, making that run more expensive than
* 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
* 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
* 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`
* 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
* 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.

Add SHA512 digests for distfiles for sysutils category
Problems found with existing digests:
Package memconf distfile memconf-2.16/memconf.gz
Problems found locating distfiles:
Package dc-tools: missing distfile dc-tools/abs0-dc-burn-netbsd-1.5-0-gae55ec9

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden). All existing
SHA1 digests retained for now as an audit trail.
