Administrator's Reference
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
