Description
|
|
|
|
~~~~~~~~~~~
|
|
|
|
|
|
|
|
This command creates a backup archive containing all files found while recursively
|
2017-03-26 23:45:45 +00:00
|
|
|
traversing all paths specified. Paths are added to the archive as they are given,
|
|
|
|
that means if relative paths are desired, the command has to be run from the correct
|
|
|
|
directory.
|
|
|
|
|
|
|
|
When giving '-' as path, borg will read data from standard input and create a
|
|
|
|
file 'stdin' in the created archive from that data.
|
2017-01-14 16:19:19 +00:00
|
|
|
|
|
|
|
The archive will consume almost no disk space for files or parts of files that
|
|
|
|
have already been stored in other archives.
|
2015-11-13 15:42:16 +00:00
|
|
|
|
2016-05-20 12:34:48 +00:00
|
|
|
The archive name needs to be unique. It must not end in '.checkpoint' or
|
|
|
|
'.checkpoint.N' (with N being a number), because these names are used for
|
|
|
|
checkpoints and treated in special ways.
|
|
|
|
|
2016-11-28 01:25:56 +00:00
|
|
|
In the archive name, you may use the following placeholders:
|
|
|
|
{now}, {utcnow}, {fqdn}, {hostname}, {user} and some others.
|
2016-03-17 02:30:31 +00:00
|
|
|
|
2017-07-23 15:12:01 +00:00
|
|
|
Backup speed is increased by not reprocessing files that are already part of
|
2017-11-25 13:35:52 +00:00
|
|
|
existing archives and weren't modified. The detection of unmodified files is
|
|
|
|
done by comparing multiple file metadata values with previous values kept in
|
|
|
|
the files cache.
|
|
|
|
|
|
|
|
This comparison can operate in different modes as given by ``--files-cache``:
|
|
|
|
|
|
|
|
- ctime,size,inode (default)
|
|
|
|
- mtime,size,inode (default behaviour of borg versions older than 1.1.0rc4)
|
|
|
|
- ctime,size (ignore the inode number)
|
|
|
|
- mtime,size (ignore the inode number)
|
|
|
|
- rechunk,ctime (all files are considered modified - rechunk, cache ctime)
|
|
|
|
- rechunk,mtime (all files are considered modified - rechunk, cache mtime)
|
|
|
|
- disabled (disable the files cache, all files considered modified - rechunk)
|
|
|
|
|
|
|
|
inode number: better safety, but often unstable on network filesystems
|
|
|
|
|
|
|
|
Normally, detecting file modifications will take inode information into
|
|
|
|
consideration to improve the reliability of file change detection.
|
|
|
|
This is problematic for files located on sshfs and similar network file
|
|
|
|
systems which do not provide stable inode numbers, such files will always
|
|
|
|
be considered modified. You can use modes without `inode` in this case to
|
|
|
|
improve performance, but reliability of change detection might be reduced.
|
|
|
|
|
|
|
|
ctime vs. mtime: safety vs. speed
|
|
|
|
|
|
|
|
- ctime is a rather safe way to detect changes to a file (metadata and contents)
|
|
|
|
as it can not be set from userspace. But, a metadata-only change will already
|
|
|
|
update the ctime, so there might be some unnecessary chunking/hashing even
|
|
|
|
without content changes. Some filesystems do not support ctime (change time).
|
|
|
|
- mtime usually works and only updates if file contents were changed. But mtime
|
|
|
|
can be arbitrarily set from userspace, e.g. to set mtime back to the same value
|
|
|
|
it had before a content change happened. This can be used maliciously as well as
|
|
|
|
well-meant, but in both cases mtime based cache modes can be problematic.
|
2016-03-17 02:30:31 +00:00
|
|
|
|
2017-03-26 23:45:45 +00:00
|
|
|
The mount points of filesystems or filesystem snapshots should be the same for every
|
|
|
|
creation of a new archive to ensure fast operation. This is because the file cache that
|
|
|
|
is used to determine changed files quickly uses absolute filenames.
|
|
|
|
If this is not possible, consider creating a bind mount to a stable location.
|
|
|
|
|
2017-06-17 10:28:42 +00:00
|
|
|
The ``--progress`` option shows (from left to right) Original, Compressed and Deduplicated
|
2017-05-17 09:52:48 +00:00
|
|
|
(O, C and D, respectively), then the Number of files (N) processed so far, followed by
|
|
|
|
the currently processed path.
|
|
|
|
|
2017-11-25 13:35:52 +00:00
|
|
|
When using ``--stats``, you will get some statistics about how much data was
|
|
|
|
added - the "This Archive" deduplicated size there is most interesting as that is
|
|
|
|
how much your repository will grow. Please note that the "All archives" stats refer to
|
|
|
|
the state after creation. Also, the ``--stats`` and ``--dry-run`` options are mutually
|
|
|
|
exclusive because the data is not actually compressed and deduplicated during a dry run.

The ``--exclude`` patterns are not like tar. In tar ``--exclude`` .bundler/gems will
|
|
|
|
exclude foo/.bundler/gems. In borg it will not, you need to use ``--exclude``
|

|
|
|
'\*/.bundler/gems' to get the same effect. See ``borg help patterns`` for
|
|
|
|
more information.

In addition to using ``--exclude`` patterns, it is possible to use
|
|
|
|
``--exclude-if-present`` to specify the name of a filesystem object (e.g. a file
|
|
|
|
or folder name) which, when contained within another folder, will prevent the
|
|
|
|
containing folder from being backed up. By default, the containing folder and
|
|
|
|
all of its contents will be omitted from the backup. If, however, you wish to
|
|
|
|
only include the objects specified by ``--exclude-if-present`` in your backup,
|
|
|
|
and not include any other contents of the containing folder, this can be enabled
|
|
|
|
through using the ``--keep-exclude-tags`` option.

Item flags
|
|
|
|
++++++++++
|
|
|
|
|
|
|
|
``--list`` outputs a list of all files, directories and other
|
|
|
|
file system items it considered (no matter whether they had content changes
|
|
|
|
or not). For each item, it prefixes a single-letter flag that indicates type
|
|
|
|
and/or status of the item.
|
|
|
|
|
|
|
|
If you are interested only in a subset of that output, you can give e.g.
|
|
|
|
``--filter=AME`` and it will only show regular files with A, M or E status (see
|
|
|
|
below).
|
|
|
|
|
|
|
|
A uppercase character represents the status of a regular file relative to the
|
|
|
|
"files" cache (not relative to the repo -- this is an issue if the files cache
|
|
|
|
is not used). Metadata is stored in any case and for 'A' and 'M' also new data
|
|
|
|
chunks are stored. For 'U' all data chunks refer to already existing chunks.
|
|
|
|
|
|
|
|
- 'A' = regular file, added (see also :ref:`a_status_oddity` in the FAQ)
|
|
|
|
- 'M' = regular file, modified
|
|
|
|
- 'U' = regular file, unchanged
|

|
|
|
- 'C' = regular file, it changed while we backed it up
|
2017-02-05 20:32:24 +00:00
|
|
|
- 'E' = regular file, an error happened while accessing/reading *this* file
|
|
|
|
|
|
|
|
A lowercase character means a file type other than a regular file,
|
|
|
|
borg usually just stores their metadata:
|
|
|
|
|
|
|
|
- 'd' = directory
|
|
|
|
- 'b' = block device
|
|
|
|
- 'c' = char device
|
|
|
|
- 'h' = regular file, hardlink (to already seen inodes)
|
|
|
|
- 's' = symlink
|
|
|
|
- 'f' = fifo
|
|
|
|
|
|
|
|
Other flags used include:
|
|
|
|
|
|
|
|
- 'i' = backup data was read from standard input (stdin)
|
|
|
|
- '-' = dry run, item was *not* backed up
|
|
|
|
- 'x' = excluded, item was *not* backed up
|
|
|
|
- '?' = missing status code (if you see this, please file a bug report!)
