NAME
amanda-applications - Application-api for amanda DESCRIPTION
Describe how to use application with Amanda APPLICATIONS
This section lists the applications included with Amanda. See the individual man pages for instructions on using them. For complete How-To information, consult the Amanda wiki at http://wiki.zmanda.com. o amgtar(8), - use GNU Tar to backup and restore data. o ampgsql(8), - use PostgreSQL's continuous WAL archiving. o amraw(8), - use open and read to read the data. o amsamba(8), - use smbclient to backup and restore data. o amstar(8), - use star to backup and restore data. o amsuntar(8), - use native tar on Solaris to backup and restore data. o amzfs-sendrecv(8), - use zfs to create a snapshot and use 'zfs send' to generate the backup. o amzfs-snapshot(8), - use zfs to create a snapshot and for use with other applications (e.g. amgtar) DEFINING APPLICATIONS
An application is defined in amanda.conf(5) as follows: define application-tool $appconfigname { plugin "$pluginname" property "$PROPERTY_NAME" "$PROPERTY_VALUE" ... } and then referenced in a dumptype as define dumptype $dumptypename { ... program "APPLICATION" application "$appconfigname" } Application properties, like Amanda configuration parameters, are insensitive to case, and - (dash) and _ (underscore) may be used interchangeably. See the individual plugin documentation for properties applicable to each plugin. SEE ALSO

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" } SEE ALSO
