./sysutils/bup, Highly efficient file backup system based on the git packfile format

Branch: CURRENT, Version: 0.29.3, Package name: bup-0.29.3, Maintainer: gdt

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.

Log message:
sysutils/bup: Update to 0.29.3

Upstream changes (other than bugfixes minor improvements):

0.29.3:

* Newer versions of par2 can process in parallel using multiple
  threads/cores, and they do so automatically.  This ends up competing
  with `bup fsck`s own parallelism, enabled by `-j`, in such a way
  that the command can actually run much *slower* (and be much more
  expensive) than it would have been with no parallelism at all.

  When appropriate `bup fsck` now disables par2's competing
  parallelism (via its `-t1` option) to avoid the contention.

0.29.0:

* An experimental `prune-older` command has been added.  It removes
  (permanently deletes) all saves except those preserved by a set of
  arguments like `--keep-monthlies-for 3y`.  See `bup help
  prune-older` for further information.
