       amzfs-sendrecv - Amanda script to create zfs sendrecv

       amzfs-sendrecv is an Amanda application implementing the Application API.
       It should not be run by users directly. It create a zfs snapshot of the
       filesystem and backup the snapshot with 'zfs send'. Snapshot are kept
       after the backup is done, this increase the disk space use on the client
       but it is neccesary to be able do to incremental backup. If you want only
       full backup, you can disable this feature by setting the KEEP-SNAPSHOT
       property to 'NO'. Only the restoration of the complete backup is allowed,
       it is impossible to restore a single file.

       The application is run as the amanda user, it must have many zfs

           zfs allow -ldu AMANDA_USER mount,create,rename,snapshot,destroy,send,receive FILESYSTEM

       Some system doesn't have "zfs allow", but you can give the Amanda backup
       user the rights to manipulate ZFS filesystems by using the following

       usermod -P "ZFS File System Management,ZFS Storage Management" AMANDA_USER
       This will require that your run zfs under pfexec, set the PFEXEC property
       to YES.

       The format of the diskdevice in the disklist (DLE) must be one of:

       Desciption              Example
       ----------              -------
       Mountpoint              /data
       ZFS pool name           datapool
       ZFS filesystem          datapool/database
       ZFS logical volume      datapool/dbvol

       The filesystem doesn't need to be mounted.

       This section lists the properties that control amzfs-sendrecv's
       functionality. See amanda-applications(7) for information on the
       Application API, application configuration.


           Path to the 'df' binary, search in $PATH by default.


           If "YES" (the default), snapshot are kept after the backup, if set to
           "NO" then snapshot are no kept and incremental backup will fail.


           Path to the 'zfs' binary, search in $PATH by default.


           Path to the 'pfexec' binary, search in $PATH by default.


           If "NO" (the default), pfexec is not used, if set to "YES" then
           pfexec is used.

       In this example, a dumptype is defined to use amzfs-sendrecv application
       to backup a zfs filesystem.
        define application-tool amzfs_sendrecv {
          comment "amzfs-sendrecv"
          plugin "amzfs-sendrecv"
          #property "DF-PATH"  "/usr/sbin/df"
          #property "KEEP-SNAPSHOT" "YES"
          #property "ZFS-PATH" "/usr/sbin/zfs"
          #property "PFEXEC-PATH" "/usr/sbin/pfexec"
          #property "PFEXEC" "NO"

        define dumptype user-zfs-sendrecv {
          program "APPLICATION"
          application "amzfs_sendrecv"
