borg-mount - Mount archive or an entire repository as a FUSE filesystem



borg-mount − Mount archive or an entire repository as a FUSE filesystem


borg [common options] mount [options] REPOSITORY_OR_ARCHIVE MOUNTPOINT [PATH...]


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.

Extra mount options

Archive filters

only consider archive names starting with this prefix.

−a GLOB−−glob−archives GLOB

only consider archive names matching the glob. sh: rules apply, see "borg help patterns". −−prefix and −−glob−archives are mutually exclusive.

−−sort−by KEYS

Comma−separated list of sorting keys; valid keys are: timestamp, name, id; default is: timestamp

−−first N

consider first N archives after other filters were applied

−−last N

consider last N archives after other filters were applied

Exclusion options

exclude paths matching PATTERN

−−exclude−from EXCLUDEFILE

read exclude patterns from EXCLUDEFILE, one per line

−−pattern PATTERN

experimental: include/exclude paths matching PATTERN

−−patterns−from PATTERNFILE

experimental: read include/exclude patterns from PATTERNFILE, one per line

−−strip−components NUMBER

Remove the specified number of leading path elements. Paths with fewer elements will be silently skipped.
