borg [common options] mount [options] REPOSITORY_OR_ARCHIVE MOUNTPOINT [PATH...]
positional arguments |
||
|
repository or archive to mount |
|
|
where to mount filesystem |
|
|
paths to extract; patterns are supported |
|
optional arguments |
||
|
stay in foreground, do not daemonize |
|
|
Extra mount options |
|
Archive filters — Archive filters can be applied to repository targets. |
||
|
only consider archive names starting with this prefix. |
|
|
only consider archive names matching the glob. sh: rules apply, see “borg help patterns”. |
|
|
Comma-separated list of sorting keys; valid keys are: timestamp, name, id; default is: timestamp |
|
|
consider first N archives after other filters were applied |
|
|
consider last N archives after other filters were applied |
|
Exclusion options |
||
|
exclude paths matching PATTERN |
|
|
read exclude patterns from EXCLUDEFILE, one per line |
|
|
experimental: include/exclude paths matching PATTERN |
|
|
experimental: read include/exclude patterns from PATTERNFILE, one per line |
|
|
Remove the specified number of leading path elements. Paths with fewer elements will be silently skipped. |
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 FUSE configuration and mount options, see the mount.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.
ignore_permissions: for security reasons the “default_permissions” mount option is internally enforced by borg. “ignore_permissions” can be given to not enforce “default_permissions”.
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.
borg [common options] umount [options] MOUNTPOINT
positional arguments |
||
|
mountpoint of the filesystem to umount |
|
This command un-mounts a FUSE filesystem that was mounted with borg mount
.
This is a convenience wrapper that just calls the platform-specific shell command - usually this is either umount or fusermount -u.
# Mounting the repository shows all archives.
# Archives are loaded lazily, expect some delay when navigating to an archive
# for the first time.
$ borg mount /path/to/repo /tmp/mymountpoint
$ ls /tmp/mymountpoint

# Archive filters are supported.

Note
borgfs
will be automatically provided if you used a distribution
package, pip
or setup.py
to install Borg. Users of the
standalone binary will have to manually create a symlink (see
Standalone Binary).
