BORG-MOUNT(1)

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

SYNOPSIS

borg [common options] mount [options] REPOSITORY_OR_ARCHIVE MOUNTPOINT

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.
