borgfs - Mount archive or an entire repository as a FUSE filesystem




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.


See borg-common(1) for common options of Borg commands.

Extra mount options

Archive filters

-P PREFIX, --prefix PREFIX
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

-e PATTERN, --exclude PATTERN
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.
