    rsync-wrapper:

     6

        Provides an rsync wrapper binary (scripts/pvlbackup-rsync-wrapper) intended to be used via ~/.ssh/authorized_keys:

     8

            command="/usr/local/bin/pvlbackup-rsync-wrapper --readonly --restrict-path=/foo" ssh-rsa ...

        XXX: the current implementation is not exactly security-audited, the restrictions serve more to avoid mistakes, and do not protect against

             determined misuse of your ssh key..

        LVM Snapshots:

    14

    15

            As an additional feature, rsync-wrapper provides support for reading LVM volumes as snapshots:

    16

    17

                rsync -ax foohost:lvm:vg00:lv00 /media/backup/foohost-lv00

    18

    19

            This will transparently create a snapshot, mount it (read-only), and run the server-side rsync from within the mounted snapshot.
