The system (server) must be stopped in order to back up or restore its system volume, so a separate server is required for backup operations. That is, at least two servers are required for this operation.
A configuration example for backup and restoration of a system volume is shown below.
Backup/restoration using a backup volume
A backup volume must be prepared.
Figure C.2 Configuration example for backup to a backup volume
Point
If the backup source server and the server used for backup operations have different operating systems, the backup volume may not be the same size as the system volume. If so, make the backup volume larger than the system volume. Allocate a slice on the backup volume as the system volume copy destination.
Backup/restoration using a backup volume and tape
A backup volume and an ETERNUS tape library must be prepared.
To manage the backup data on tape media, install software (TSM) for operating an ETERNUS tape library on the server used for backup operations and use it as a Tape Server.
Figure C.3 Configuration example when a backup volume is used to backup to tape media
Point
If the backup source server and the server used for backup operations have different operating systems, the backup volume may not be the same size as the system volume. If so, make the backup volume larger than the system volume. Allocate a slice on the backup volume as the system volume copy destination. The backup to tape operations backs up the system volume data that was copied to the slice.
Note
In the configuration example above, the server that performs the backup/restore operation is also used as a Tape Server, but the operating system supported as a Tape Server is Solaris.
Therefore, if the operating system of the server that performs the backup/restore operations is not Solaris, a separate Tape Server is required.
Backup and restoration using tape directly
An ETERNUS tape library must be provided.
To manage the backup data on tape media, install software (TSM) for operating an ETERNUS tape library on the server used for backup operations and use it as a Tape Server.
Figure C.4 Configuration example for backup directly to tape media
Note
When the system volume is backed up or restored directly to or from tape, the backup/restoration must be in LU (disk) units.
Note
In the above configuration example, the server that performs the backup/restoration operation is also used as a Tape Server, but the only operating system that supports use as a Tape Server is Solaris.
Therefore, if the operating system of the server that performs backup/restoration is not Solaris, a separate Tape Server is required.
