Borg Changelog
|
|
==============
|
|
|
|
|
|
Version 0.24.0
|
|
--------------
|
|
|
|
Incompatible changes (compared to 0.23):
|
|
|
|
- borg now always issues --umask NNN option when invoking another borg via ssh
|
|
on the repository server. By that, it's making sure it uses the same umask
|
|
for remote repos as for local ones. Because of this, you must upgrade both
|
|
server and client(s) to 0.24.
|
|
- the default umask is 077 now (if you do not specify via --umask) which might
|
|
be a different one as you used previously. The default umask avoids that
|
|
you accidentally give access permissions for group and/or others to files
|
|
created by borg (e.g. the repository).
|
|
|
|
Deprecations:
|
|
|
|
- "--encryption passphrase" mode is deprecated, see #85 and #97.
|
|
See the new "--encryption repokey" mode for a replacement.
|
|
|
|
New features:
|
|
|
|
- borg create --chunker-params ... to configure the chunker, fixes #16
|
|
(attic #302, attic #300, and somehow also #41).
|
|
This can be used to reduce memory usage caused by chunk management overhead,
|
|
so borg does not create a huge chunks index/repo index and eats all your RAM
|
|
if you back up lots of data in huge files (like VM disk images).
|
|
See docs/misc/create_chunker-params.txt for more information.
|
|
- borg info now reports chunk counts in the chunk index.
|
|
- borg create --compression 0..9 to select zlib compression level, fixes #66
|
|
(attic #295).
|
|
- borg init --encryption repokey (to store the encryption key into the repo),
|
|
fixes #85
|
|
- improve at-end error logging, always log exceptions and set exit_code=1
|
|
- LoggedIO: better error checks / exceptions / exception handling
|
|
- implement --remote-path to allow non-default-path borg locations, #125
|
|
- implement --umask M and use 077 as default umask for better security, #117
|
|
- borg check: give a named single archive to it, fixes #139
|
|
- cache sync: show progress indication
|
|
- cache sync: reimplement the chunk index merging in C
|
|
|
|
Bug fixes:
|
|
|
|
- fix segfault that happened for unreadable files (chunker: n needs to be a
|
|
signed size_t), #116
|
|
- fix the repair mode, #144
|
|
- repo delete: add destroy to allowed rpc methods, fixes issue #114
|
|
- more compatible repository locking code (based on mkdir), maybe fixes #92
|
|
(attic #317, attic #201).
|
|
- better Exception msg if no Borg is installed on the remote repo server, #56
|
|
- create a RepositoryCache implementation that can cope with >2GiB,
|
|
fixes attic #326.
|
|
- fix Traceback when running check --repair, attic #232
|
|
- clarify help text, fixes #73.
|
|
- add help string for --no-files-cache, fixes #140
|
|
|
|
Other changes:
|
|
|
|
- improved docs:
|
|
|
|
- added docs/misc directory for misc. writeups that won't be included
|
|
"as is" into the html docs.
|
|
- document environment variables and return codes (attic #324, attic #52)
|
|
- web site: add related projects, fix web site url, IRC #borgbackup
|
|
- Fedora/Fedora-based install instructions added to docs
|
|
- Cygwin-based install instructions added to docs
|
|
- updated AUTHORS
|
|
- add FAQ entries about redundancy / integrity
|
|

|
|
- update internals doc about chunker params, memory usage and compression
|
|
- added docs about development
|
|
- add some words about resource usage in general
|
|
- document how to backup a raw disk
|
|

|
|
|
|
- use borg-tmp as prefix for temporary files / directories
|
|
- short prune options without "keep-" are deprecated, do not suggest them
|
|
- improved tox configuration
|
|
- remove usage of unittest.mock, always use mock from pypi
|
|
- use entrypoints instead of scripts, for better use of the wheel format and
|
|
modern installs
|
|
- add requirements.d/development.txt and modify tox.ini
|
|
- use travis-ci for testing based on Linux and (new) OS X
|
|
- use coverage.py, pytest-cov and codecov.io for test coverage support
|
|
|
|
I forgot to list some stuff already implemented in 0.23.0, here they are:
|
|
|
|
New features:
|
|
|
|
- efficient archive list from manifest, meaning a big speedup for slow
|
|
repo connections and "list <repo>", "delete <repo>", "prune" (attic #242,
|
|
attic #167)
|
|
- big speedup for chunks cache sync (esp. for slow repo connections), fixes #18
|
|
- hashindex: improve error messages
|
|
|
|
Other changes:
|
|
|
|
- explicitly specify binary mode to open binary files
|
|
- some easy micro optimizations
|
|
|
|
|
|
Version 0.23.0

|
--------------
|
|
|
|
Incompatible changes (compared to attic, fork related):
|

|
- changed sw name and cli command to "borg", updated docs
|
|
- package name (and name in urls) uses "borgbackup" to have less collisions
|
|
- changed repo / cache internal magic strings from ATTIC* to BORG*,
|
|
changed cache location to .cache/borg/ - this means that it currently won't
|
|
accept attic repos (see issue #21 about improving that)

always fails

|
|

|
|
|
|

|
|
- check: sort archives in reverse time order
