BORGFS(1)

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

SYNOPSIS

borgfs [options] REPOSITORY_OR_ARCHIVE MOUNTPOINT [PATH...]

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 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.

OPTIONS

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

    where to mount filesystem

PATH
    paths to extract; patterns are supported

  optional arguments

    show version number and exit

-f, --foreground
    stay in foreground, do not daemonize

-o  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

--exclude-from EXCLUDEFILE
    read exclude patterns from EXCLUDEFILE, one per line

--pattern PATTERN
    experimental: include/exclude paths matching PATTERN
