./sysutils/py-borgbackup, Deduplicating backup program with compression and encryption

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 1.1.9, Package name: py37-borgbackup-1.1.9, Maintainer: bsiegert

BorgBackup (short: Borg) is a deduplicating backup program. Optionally,
it supports compression and authenticated encryption.

The main goal of Borg is to provide an efficient and secure way to
backup data. The data deduplication technique used makes Borg suitable
for daily backups since only changes are stored. The authenticated
encryption technique makes it suitable for backups to not fully trusted
targets.

Log message:
Update py-borgbackup to 1.1.6.

Version 1.1.6 (2018-06-11)
--------------------------

Compatibility notes:

- When upgrading from borg 1.0.x to 1.1.x, please note:

  - read all the compatibility notes for 1.1.0*, starting from 1.1.0b1.
  - borg upgrade: you do not need to and you also should not run it.
  - borg might ask some security-related questions once after upgrading.
    You can answer them either manually or via environment variable.
    One known case is if you use unencrypted repositories, then it will ask
    about a unknown unencrypted repository one time.
  - your first backup with 1.1.x might be significantly slower (it might
    completely read, chunk, hash a lot files) - this is due to the
    --files-cache mode change (and happens every time you change mode).
    You can avoid the one-time slowdown by using the pre-1.1.0rc4-compatible
    mode (but that is less safe for detecting changed files than the default).
    See the --files-cache docs for details.
- 1.1.6 changes:

  - also allow msgpack-python 0.5.6.

Fixes:

- fix borg exception handling on ENOSPC error with xattrs, #3808
- prune: fix/improve overall progress display
- borg config repo ... does not need cache/manifest/key, #3802
- debug dump-repo-objs should not depend on a manifest obj
- pypi package:

  - include .coveragerc, needed by tox.ini
  - fix package long description, #3854

New features:

  - implement --dry-run, #3822
- check:

  - show progress while rebuilding missing manifest, #3787
  - more --repair output

- update bundled lz4 code to 1.8.2, #3870
- docs:

New features:

- create: implement --stdin-name, #3533

  - clarify path semantics when matching, #3598
  - link to offline documentation from README, #3502

  - move cleanup steps to fs_init, #3706
  - the boxcutter wheezy boxes are 404, use local ones

- prune: fix building the "borg prune" man page, #3398
- init: use given --storage-quota for local repo, #3470
- init: properly quote repo path in output
- fix startup delay with dns-only own fqdn resolving, #3471

New features:

- added zstd compression. try it!
- added placeholder {reverse-fqdn} for fqdn in reverse notation
- added BORG_BASE_DIR environment variable, #3338

Other changes:

- list help topics when invalid topic is requested

  - docs update for lz4 b2 zstd changes
  - add zstd to compression help, readme, docs
  - update requirements and install docs about bundled lz4 and zstd
- refactored build of the compress and crypto.low_level extensions, #3415:

  - move some lib/build related code to setup_{zstd,lz4,b2}.py
  - bundle lz4 1.8.0 (requirement: >= 1.7.0 / r129)
  - bundle zstd 1.3.2 (requirement: >= 1.3.0)
  - blake2 was already bundled
  - rename BORG_LZ4_PREFIX env var to BORG_LIBLZ4_PREFIX for better consistency:
    we also have BORG_LIBB2_PREFIX and BORG_LIBZSTD_PREFIX now.
  - add prefer_system_lib* = True settings to setup.py - by default the build
    will prefer a shared library over the bundled code, if library and headers
    can be found and meet the minimum requirements.

Pre-1.1.4 potential data corruption issue
-----------------------------------------

A data corruption bug was discovered in borg check --repair, see issue #3444.

This is a 1.1.x regression, releases < 1.1 (e.g. 1.0.x) are not affected.

To avoid data loss, you must not run borg check --repair using an unfixed version
of borg 1.1.x. The first official release that has the fix is 1.1.4.

Package maintainers may have applied the fix to updated packages of 1.1.x (x<4)
though, see the package maintainer's package changelog to make sure.

If you never had missing item metadata chunks, the bug has not affected you
even if you did run borg check --repair with an unfixed version.

When borg check --repair tried to repair corrupt archives that miss item metadata
chunks, the resync to valid metadata in still present item metadata chunks
malfunctioned. This was due to a broken validator that considered all (even valid)
item metadata as invalid. As they were considered invalid, borg discarded them.
Practically, that means the affected files, directories or other fs objects were
discarded from the archive.

Due to the malfunction, the process was extremely slow, but if you let it
complete, borg would have created a "repaired" archive that has lost a \ 
lot of items.
If you interrupted borg check --repair because it was so strangely slow (killing
borg somehow, e.g. Ctrl-C) the transaction was rolled back and no corruption \ 
occurred.

The log message indicating the precondition for the bug triggering looks like:

    item metadata chunk missing [chunk: 001056_bdee87d...a3e50d]

If you never had that in your borg check --repair runs, you're not affected.

But if you're unsure or you actually have seen that, better check your archives.
By just using "borg list repo::archive" you can see if all expected \ 
filesystem
items are listed.
