       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 command:

       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"
