BACKUP NODE (Back Up a NAS Node)

Use this command to start a backup operation for a network-attached storage (NAS) node.

Backups that are created for NAS nodes with this BACKUP NODE command are functionally equivalent to backups that are created by using the BACKUP NAS command on a Tivoli Storage Manager client. You can restore these backups with either the server's RESTORE NODE command or the client's RESTORE NAS command.

Privilege Class

To issue this command, you must have system privilege, policy privilege for the domain to which the node is assigned, or client owner authority over the node.

Parameters

node_name (Required)
Specifies the node for which the backup will be performed. You cannot use wildcard characters or specify a list of names.

file_system_name
Specifies the name of one or more file systems to back up. The file system name that you specify cannot contain wildcard characters. You can specify more than one file system by separating the names with commas and no intervening spaces. If you do not specify a file system, all file systems will be backed up. In determining the file systems to process, the server will not use any DOMAIN.NAS, INCLUDE.FS.NAS, or EXCLUDE.FS.NAS statements in any client option file or client option set. If you back up multiple file systems, each file system backs up as a separate server process.

MGmtclass
Specifies the name of the management class to which this backup data is bound. If you do not specify a management class, the backup data is bound to the default management class of the policy domain to which the node is assigned. In determining the management class, the server will not use any INCLUDE.FS.NAS statements in any client option file or client option set.

MODE

Specifies whether the file system backups are full or differential. The default is DIFFERENTIAL.

FULL
Specifies to back up the entire file system.

DIFFerential
Specifies to back up only the files that have changed since the most recent full backup. If you choose a differential backup, and a full backup is not found, a full backup is performed.

Wait
Specifies whether to wait for the server to complete processing this command in the foreground. The default is NO. Possible values are:

No
Specifies that the server processes this command in the background. Use the QUERY PROCESS command to monitor the background processing of this command.

Yes
Specifies that the server processes this command in the foreground. You wait for the command to complete before continuing with other tasks. The server then displays the output messages to the administrative client when the command completes. If you are backing up multiple file systems, all backup processes must complete before the command is complete.
Note:
You cannot specify Wait=Yes from the server console.

Examples

Task

Perform a full backup on the /vol/vol10 file system of NAS node NAS1.

Command:
backup node nas1 /vol/vol10 mode=full
