Snapshot-based file backup and archive and snapshot-based image backup

For backup-archive clients running on AIX® 5.3 or later JFS2 file systems as root user, snapshot-based image backup is created using snapshots by default.

About this task

Optionally, you can enable snapshot-based file level backup and archive operations by specifying the snapshotproviderfs option. If for some reason a snapshot cannot be taken, the client attempts to perform a static image backup or regular file backup.

If you want to specify snapshot-based file backup and archive, set the option snapshotproviderfs to JFS2. This is applicable to all JFS2 file systems for that client.

Important: Use snapshot-based file backup and archive and snapshot-based image backup for all of your AIX JFS2 file systems.

For example, to turn on snapshot-based file backup and archive for all JFS2 file systems on the client, specify the following in the server stanza in the dsm.sys file:

     snapshotproviderfs JFS2

To explicitly turn off snapshot-based file backup and archive for all JFS2 file systems on the client, specify the following in the server stanza in the dsm.sys file:

     snapshotproviderfs   NONE

To turn on snapshot-based file backup and archive for only one specific JFS2 file system on the client, specify the following in the server stanza in the dsm.sys file:

     snapshotproviderfs   NONE

     include.fs   /kalafs1   snapshotproviderfs=JFS2

To turn off snapshot-based file backup and archive for only one specific JFS2 file system on the client, specify the following in the server stanza in the dsm.sys file:

     snapshotproviderfs   JFS2

     include.fs    /kalafs2    snapshotproviderfs=NONE

To turn on snapshot-based file backup and archive for only one specific operation on the client, specify the following on the command line:

     dsmc incr   -snapshotproviderfs=JFS2  /kalafs1

To turn off snapshot-based file backup and archive for only one specific operation on the client, specify the following in the server stanza in the dsm.sys file:

      snapshotproviderfs   JFS2

Then perform the backup command. For example:

      dsmc incr -snapshotproviderfs=NONE /kalafs2
