bup-fuse

bup-fuse(1)						      General Commands Manual						       bup-fuse(1)

NAME

       bup-fuse - mount a bup repository as a filesystem

SYNOPSIS

       bup fuse [-d] [-f] [-o] <mountpoint>

DESCRIPTION

       bup fuse opens a bup repository and exports it as a fuse(7) userspace filesystem.

       This feature is only available on systems (such as Linux) which support FUSE.

       WARNING: bup fuse is still experimental and does not enforce any file permissions! All files will be readable by all users.

       When you're done accessing the mounted fuse filesystem, you should unmount it with umount(8).

OPTIONS

       -d, --debug
	      run in the foreground and print FUSE debug information for each request.

       -f, --foreground
	      run in the foreground and exit only when the filesystem is unmounted.

       -o, --allow-other
	      permit other users to access the filesystem.  Necessary for exporting the filesystem via Samba, for example.

EXAMPLE

	      rm -rf /tmp/buptest
	      mkdir /tmp/buptest
	      sudo bup fuse -d /tmp/buptest
	      ls /tmp/buptest/*/latest
	      ...
	      umount /tmp/buptest

SEE ALSO

       fuse(7), fusermount(1), bup-ls(1), bup-ftp(1), bup-restore(1), bup-web(1)

BUP

       Part of the bup(1) suite.
