amzfs-snapshot

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

NAME

       amzfs-snapshot - Amanda script to create zfs snapshot

DESCRIPTION

       amzfs-snapshot is an Amanda script implementing the Script API. It should not be run by users directly. It create a zfs snapshot of the
       filesystem where the path specified is mounted.

       PRE-DLE-* create a snapshot and the POST-DLE-* destroy the snapshot, *-DLE-AMCHECK, *-DLE-ESTIMATE and *-DLE-BACKUP must be set to be
       executed on the client:

	   execute-on  pre-dle-amcheck, post-dle-amcheck, pre-dle-estimate, post-dle-estimate, pre-dle-backup, post-dle-backup
	   execute-where client

       The PRE_DLE_* script output a DIRECTORY property telling where the directory is located in the snapshot. The application must be able to
       use the DIRECTORY property, amgtar can do it.

       The script is run as the amanda user, it must have the priviledge to create and destroy snapshot:

	   zfs allow -ldu AMANDA_USER mount,snapshot,destroy 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 DLE must be one of:

       Desciption	       Example
       ----------	       -------
       Mountpoint	       /data
       Arbitrary mounted dir   /data/interesting_dir
       ZFS pool name	       datapool
       ZFS filesystem	       datapool/database
       ZFS logical volume      datapool/dbvol

       The filesystem must be mounted.

PROPERTIES

       This section lists the properties that control amzfs-snapshot's functionality. See amanda-scripts(7) for information on the Script API,
       script configuration.

       DF-PATH

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

       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-snapshot script to create a snapshot and use amgtar to backup the snapshot.
	define script-tool amzfs_snapshot {
	  comment "backup of zfs snapshot"
	  plugin  "amzfs-snapshot"
	  execute-on  pre-dle-amcheck, post-dle-amcheck, pre-dle-estimate, post-dle-estimate, pre-dle-backup, post-dle-backup
	  execute-where client
	  #property "DF-PATH" "/usr/sbin/df"
	  #property "ZFS-PATH" "/usr/sbin/zfs"
	  #property "PFEXEC-PATH" "/usr/sbin/pfexec"
	  #property "PFEXEC" "NO"
	}

	define dumptype user-zfs-amgtar {
	  dt_amgtar
	  script "amzfs_snapshot"
	}
