convert most print() calls to logging
the logging level varies: most is logging.info(), in some place
logging.warning() or logging.error() are used when the condition is
clearly an error or warning. in other cases, we keep using print, but
force writing to sys.stderr, unless we interact with the user.
there were 77 calls to print before this commit, now there are 7, most
of which in the archiver module, which interacts directly with the
user. in one case there, we still use print() only because logging is
not setup properly yet during argument parsing.
it could be argued that commands like info or list should use print
directly, but we have converted them anyways, without ill effects on
the unit tests
unit tests still use print() in some places
this switches all informational output to stderr, which should help
with, if not fix jborg/attic#312 directly

|
|
Exclusion patterns support four separate styles, fnmatch, shell, regular
|
2016-01-18 12:09:08 +00:00
|
|
|
expressions and path prefixes. If followed by a colon (':') the first two
|
|
|
|
characters of a pattern are used as a style selector. Explicit style
|
|
|
|
selection is necessary when a non-default style is desired or when the
|
|
|
|
desired pattern starts with two alphanumeric characters followed by a colon
|
|
|
|
(i.e. `aa:something/*`).
|
2015-12-15 23:14:02 +00:00
|
|

|
2016-01-21 13:24:32 +00:00
|
|
|
`Fnmatch <https://docs.python.org/3/library/fnmatch.html>`_, selector `fm:`
|
|
|
|
|
|
|
|
These patterns use a variant of shell pattern syntax, with '*' matching
|
|
|
|
any number of characters, '?' matching any single character, '[...]'
|
|
|
|
matching any single character specified, including ranges, and '[!...]'
|
|
|
|
matching any character not specified. For the purpose of these patterns,
|
|
|
|
the path separator ('\\' for Windows and '/' on other systems) is not
|
2016-01-21 13:24:35 +00:00
|
|
|
treated specially. Wrap meta-characters in brackets for a literal match
|
|
|
|
(i.e. `[?]` to match the literal character `?`). For a path to match
|
|
|
|
a pattern, it must completely match from start to end, or must match from
|
|
|
|
the start to just before a path separator. Except for the root path,
|
|
|
|
paths will never end in the path separator when matching is attempted.
|
|
|
|
Thus, if a given pattern ends in a path separator, a '*' is appended
|
|
|
|
before matching is attempted.
|
|
|
|
|
|
|
|
Shell-style patterns, selector `sh:`
|
|
|
|
|
|
|
|
Like fnmatch patterns these are similar to shell patterns. The difference
|
|
|
|
is that the pattern may include `**/` for matching zero or more directory
|
|
|
|
levels, `*` for matching zero or more arbitrary characters with the
|
|
|
|
exception of any path separator.
|
2016-01-21 13:24:32 +00:00
|
|
|
|
|
|
|
Regular expressions, selector `re:`
|
|
|
|
|
|
|
|
Regular expressions similar to those found in Perl are supported. Unlike
|
|
|
|
shell patterns regular expressions are not required to match the complete
|
|
|
|
path and any substring match is sufficient. It is strongly recommended to
|
|
|
|
anchor patterns to the start ('^'), to the end ('$') or both. Path
|
|
|
|
separators ('\\' for Windows and '/' on other systems) in paths are
|
|
|
|
always normalized to a forward slash ('/') before applying a pattern. The
|
|
|
|
regular expression syntax is described in the `Python documentation for
|
|
|
|
the re module <https://docs.python.org/3/library/re.html>`_.
|
|
|
|
|
|
|
|
Prefix path, selector `pp:`
|
|
|
|
|
|
|
|
This pattern style is useful to match whole sub-directories. The pattern
|
|
|
|
`pp:/data/bar` matches `/data/bar` and everything therein.
|
2016-01-18 12:09:08 +00:00
|
|
|
|
2015-12-15 23:14:02 +00:00
|
|
|
Exclusions can be passed via the command line option `--exclude`. When used
|
|
|
|
from within a shell the patterns should be quoted to protect them from
|
|
|
|
expansion.
|
|
|
|
|
|
|
|
The `--exclude-from` option permits loading exclusion patterns from a text
|
2016-01-13 13:30:54 +00:00
|
|
|
file with one pattern per line. Lines empty or starting with the number sign
|
|
|
|
('#') after removing whitespace on both ends are ignored. The optional style
|
|
|
|
selector prefix is also supported for patterns loaded from a file. Due to
|
|
|
|
whitespace removal paths with whitespace at the beginning or end can only be
|
|
|
|
excluded using regular expressions.

The check command verifies the consistency of a repository and the corresponding archives.
|
|
|
|
|
|
|
|
First, the underlying repository data files are checked:
|
2015-08-29 02:00:22 +00:00
|
|
|
|
2015-08-08 22:36:17 +00:00
|
|
|
- For all segments the segment magic (header) is checked
|
|
|
|
- For all objects stored in the segments, all metadata (e.g. crc and size) and
|
|
|
|
all data is read. The read data is checked by size and CRC. Bit rot and other
|
|
|
|
types of accidental damage can be detected this way.
|
|
|
|
- If we are in repair mode and a integrity error is detected for a segment,
|
|
|
|
we try to recover as many objects from the segment as possible.
|
|
|
|
- In repair mode, it makes sure that the index is consistent with the data
|
|
|
|
stored in the segments.
|
|
|
|
- If you use a remote repo server via ssh:, the repo check is executed on the
|
|
|
|
repo server without causing significant network traffic.
|
|
|
|
- The repository check can be skipped using the --archives-only option.
|
|
|
|
|
|
|
|
Second, the consistency and correctness of the archive metadata is verified:
|
2015-08-29 02:00:22 +00:00
|
|
|
|
2015-08-08 22:36:17 +00:00
|
|
|
- Is the repo manifest present? If not, it is rebuilt from archive metadata
|
2015-08-09 10:52:39 +00:00
|
|
|
chunks (this requires reading and decrypting of all metadata and data).
|
2015-08-08 22:36:17 +00:00
|
|
|
- Check if archive metadata chunk is present. if not, remove archive from
|
|
|
|
manifest.
|
|
|
|
- For all files (items) in the archive, for all chunks referenced by these
|
|
|
|
files, check if chunk is present (if not and we are in repair mode, replace
|
2015-08-09 10:52:39 +00:00
|
|
|
it with a same-size chunk of zeros). This requires reading of archive and
|
|
|
|
file metadata, but not data.
|
2015-08-08 22:36:17 +00:00
|
|
|
- If we are in repair mode and we checked all the archives: delete orphaned
|
2015-08-09 10:52:39 +00:00
|
|
|
chunks from the repo.
|
2015-08-08 22:36:17 +00:00
|
|
|
- if you use a remote repo server via ssh:, the archive check is executed on
|
|
|
|
the client machine (because if encryption is enabled, the checks will require
|
|
|
|
decryption and this is always done client-side, because key access will be
|
2015-08-09 10:52:39 +00:00
|
|
|
required).
|
2015-08-08 22:36:17 +00:00
|
|
|
- The archive checks can be time consuming, they can be skipped using the
|
|
|
|
--repository-only option.

|
|
The prune command prunes a repository by deleting archives not matching
|
|
|
|
any of the specified retention options. This command is normally used by
|
|
|
|
automated backup scripts wanting to keep a certain number of historic backups.
|
|
|
|
|
2016-01-29 00:40:29 +00:00
|
|
|
As an example, "-d 7" means to keep the latest backup on each day, up to 7
|
|
|
|
most recent days with backups (days without backups do not count).
|
2014-04-06 13:16:25 +00:00
|
|
|
The rules are applied from hourly to yearly, and backups selected by previous
|
|
|
|
rules do not count towards those of later rules. The time that each backup
|
|
|
|
completes is used for pruning purposes. Dates and times are interpreted in
|
2014-02-04 01:11:47 +00:00
|
|
|
the local timezone, and weeks go from Monday to Sunday. Specifying a

2014-02-25 00:32:18 +00:00

The "--keep-within" option takes an argument of the form "<int><char>",
|
|
|
|
where char is "H", "d", "w", "m", "y". For example, "--keep-within 2d" means
|
2014-02-08 20:37:27 +00:00
|
|
|
to keep all archives that were created within the past 48 hours.
|
|
|
|
"1m" is taken to mean "31d". The archives kept with this option do not
|
2014-04-06 13:16:25 +00:00
|
|
|
count towards the totals specified by any other options.

2016-01-24 01:49:12 +00:00

If a prefix is set with -P, then only archives that start with the prefix are
|
2014-04-06 13:16:25 +00:00

considered for deletion and only those archives count towards the totals

do not upgrade repositories in place by default
instead, we perform the equivalent of `cp -al` on the repository to
keep a backup, and then rewrite the files, breaking the hardlinks as
necessary.
it has to be confirmed that the rest of Borg will also break hardlinks
when operating on files in the repository. if Borg operates in place
on any files of the repository, it could jeoperdize the backup, so
this needs to be verified. I believe that most files are written to a
temporary file and moved into place, however, so the backup should be
safe.
the rationale behind the backup copy is that we want to be extra
careful with user's data by default. the old behavior is retained
through the `--inplace`/`-i` commandline flag. plus, this way we don't
need to tell users to go through extra steps (`cp -a`, in particular)
before running the command.
also, it can take a long time to do the copy of the attic repository
we wish to work on. since `cp -a` doesn't provide progress
information, the new default behavior provides a nicer user experience
of giving an overall impression of the upgrade progress, while
retaining compatibility with Attic by default (in a separate
repository, of course).
this makes the upgrade command much less scary to use and hopefully
will convert drones to the borg collective.
the only place where the default inplace behavior is retained is in
the header_replace() function, to avoid breaking the cache conversion
code and to keep API stability and semantic coherence ("replace" by
defaults means in place).

need to tell users to go through extra steps (`cp -a`, in particular)
before running the command.
also, it can take a long time to do the copy of the attic repository
we wish to work on. since `cp -a` doesn't provide progress
information, the new default behavior provides a nicer user experience
of giving an overall impression of the upgrade progress, while
retaining compatibility with Attic by default (in a separate
repository, of course).
this makes the upgrade command much less scary to use and hopefully
will convert drones to the borg collective.
the only place where the default inplace behavior is retained is in
the header_replace() function, to avoid breaking the cache conversion
code and to keep API stability and semantic coherence ("replace" by
defaults means in place).
