Update installation instructions so that the following error won't occur:
gcc: error: /usr/lib/rpm/redhat/redhat-hardened-cc1: No such file or directory
error: command 'gcc' failed with exit status 1
/mnt/backup was confusing as people like to mount their backup disk on /mnt/backup,
but borg init /mnt/backup does not work if that directory already exists because it is
the mountpoint. it would work, if /mnt was the mountpoint, but that is not obvious
and also unusual.
Use with caution: permanent data loss by specifying incorrect patterns
is easily possible. Make a dry run to make sure you got everything right.
borg recreate has many uses:
- Can selectively remove files/dirs from old archives, e.g. to free
space or purging picturarum biggus dickus from history
- Recompress data
- Rechunkify data, to have upgraded Attic / Borg 0.xx archives deduplicate
with Borg 1.x archives. (Or to experiment with chunker-params for
specific use cases
It is interrupt- and resumable.
Chunks are not freed on-the-fly.
Rationale:
Makes only sense when rechunkifying, but logic on which new chunks to
free what input chunks is complicated and *very* delicate.
Future TODOs:
- Refactor tests using py.test fixtures
-- would require porting ArchiverTestCase to py.test: many changes,
this changeset is already borderline too large.
- Possibly add a --target option to not replace the source archive
-- with the target possibly in another Repo
(better than "cp" due to full integrity checking, and deduplication
at the target)
- Detect and skip (unless --always-recompress) already recompressed chunks
Fixes#787#686#630#70 (and probably some I overlooked)
Also see #757 and #770
- Group options
- Nicer list of options in Sphinx
- Deduplicate 'Common options'
(including --help)
The latter is done by explicitly declaring --help in the common_parser,
which is then inherited by the sub-parsers; no change in observable
behaviour.
ubuntu was showing up twice in the list of supported OSes... it seems it was because the line was getting too long, so I removed the "names" and kept only the numbers to keep the line short.
- Archives now have a new metadata field 'comment'
- 'info' command shows a comment if it's present
- 'create' command now has option '--comment' for adding comments to archives.
- A new command 'comment' is added for modifying the comments on existing
archives.
Resolves#842.
it's not recommended to suppress warnings or errors,
but the user may decide this on his own.
note: --warning is not given to borg serve so a <= 1.0.0 borg
will still work as server. it is not needed as it is the default.
Previously, on 'borg diff', the output always had first the modifications, then
additions, and finally removals. Output may be easier to follow if the various
kinds of changes are interleaved. This commit is a simple solution that first
collects the output lines and sorts them by file path before printing. This new
behavior is optional and disabled by default. It can be enabled with '--sort'
command line option.
This option will be especially useful after the planned multi-threading changes
arrive. Multi-threading may shuffle the archive order of files making diff
output hard to follow without sorting.
Resolves#797.
Makes it easy to see paths excluded by --exclude* options for testing of
regexes, and for ongoing monitoring that files desired for backup aren't
getting excluded accidentally.
The main design goals of the new format:
- One file takes exactly one line of output
- The format is easy to read with typical, long list of changes
- Metadata changes are visible and easy to examine
- Unuseful information is not shown
Resolves#757.
- add archiver.main_mount()
- provide borgfs behaviour when the monolithic binary is called via a
symlink called borgfs
- docs: update usage of mount subcommand, provide examples for borgfs and
add symlink creation to standalone binary installation
- run build_usage
- add entry point in setup.py
- patch helpers.py:get_keys_dir() to allow mounting fstab entries with
"user" option set
Without this, setuid() called at some point by mount changes the HOME
environment variable to '/root' and os.expanduser('~') would return
'/root' as well, thus the mount would fail with
PermissionError: [Errno 13] Permission denied: '/root/.config'
After setuid(), the HOME variable stays intact, so we still can
explicitly query USER's home.
Also, os.path.expanduser() behaves differently for '~' and '~someuser'
as parameters: when called with an explicit username, the possibly set
environment variable HOME is no longer respected. So we have to check if
it is set and only expand the user's home directory if HOME is unset.
- add myself to AUTHORS
it is important to first do all the changes that modify the release contents,
then tag/sign it, then build the binaries via vagrant.
Only then the binaries will have the correct version number.
refactorings:
- introduced concept of default answer:
if the answer string is in the defaultish sequence, the return value of yes() will be the default.
e.g. if just pressing <enter> when asked on the console or if an empty string or "default" is
in the environment variable for overriding.
if an environment var has an invalid value and no retries are enabled: return default
if retries are enabled, next retry won't use the env var again, but either ask via input().
- simplify:
only one default - this should be a SAFE default as it is used in some special conditions
like EOF or invalid input with retries disallowed.
no isatty() magic, the "yes" shell command exists, so we could receive input even if it is not from a tty.
- clean:
separate retry flag from retry_msg
one of the biggest issues with borg < 1.0 was that it had a default target chunk
size of 64kiB, thus it created a lot of chunks, a huge chunk management overhead
(high RAM and disk usage).
