Version 0.26.1 (2015-09-28)
This is a minor update, just docs and new pyinstaller binaries.
- docs update about python and binary requirements
- better docs for --read-special, fix #220
- re-built the binaries, fix #218 and #213 (glibc version issue)
- update web site about single-file pyinstaller binaries
Note: if you did a python-based installation, there is no need to upgrade.
Version 0.24.0 (2015-08-09)
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
- clarify that borg extract uses the cwd as extraction target
- 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
- add note about how to run borg from virtual env
- add solutions for (ll)fuse installation problems
- document what borg check does, fixes #138
- reorganize borgbackup.github.io sidebar, prev/next at top
- deduplicate and refactor the docs / README.rst
- 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
