Description
~~~~~~~~~~~
This command mounts an archive as a FUSE filesystem. This can be useful for
browsing an archive or restoring individual files. Unless the ``--foreground``
option is given the command will run in the background until the filesystem
is ``umounted``.
The command ``borgfs`` provides a wrapper for ``borg mount``. This can also be
used in fstab entries:
``/path/to/repo /mnt/point fuse.borgfs defaults,noauto 0 0``
To allow a regular user to use fstab entries, add the ``user`` option:
``/path/to/repo /mnt/point fuse.borgfs defaults,noauto,user 0 0``
For mount options, see the fuse(8) manual page. Additional mount options
supported by borg:
- versions: when used with a repository mount, this gives a merged, versioned
view of the files in the archives. EXPERIMENTAL, layout may change in future.
- allow_damaged_files: by default damaged files (where missing chunks were
replaced with runs of zeros by borg check ``--repair``) are not readable and
return EIO (I/O error). Set this option to read such files.
The BORG_MOUNT_DATA_CACHE_ENTRIES environment variable is meant for advanced users
to tweak the performance. It sets the number of cached data chunks; additional
memory usage can be up to ~8 MiB times this number. The default is the number
of CPU cores.
When the daemonized process receives a signal or crashes, it does not unmount.
Unmounting in these cases could cause an active rsync or similar process
to unintentionally delete data.
When running in the foreground ^C/SIGINT unmounts cleanly, but other
signals or crashes do not.

Backup speed is increased by not reprocessing files that are already part of

will take inode information into consideration. This is problematic for files
located on sshfs and similar network file systems which do not provide stable

``--ignore-inode`` flag can be used to prevent this and improve performance.
This flag will reduce reliability of change detection however, with files

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.
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

Important: running borg recreate to re-chunk will remove the chunks_healthy
metadata of all items with replacement chunks, so healing will not be possible
any more after re-chunking (it is also unlikely it would ever work: due to the
change of chunking parameters, the missing chunk likely will never be seen again
even if you still have the data that produced it).
