AMZFS-SENDRECV(8)	System Administration Commands	     AMZFS-SENDRECV(8)

NAME
       amzfs-sendrecv -	Amanda script to create	zfs sendrecv

DESCRIPTION
       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	necessary 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
       privilege:

	   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.

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

       DF-PATH

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

       KEEP-SNAPSHOT

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

       ZFS-PATH

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

       PFEXEC-PATH

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

       PFEXEC

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

EXAMPLE
       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"
	}
