Dumps to, and Loads from, Multiple Devices

Backup Server divides the database into approximately equal portions, and sends each portion to a different device.

Dumps are made concurrently on all devices, reducing the time required to dump an individual database or transaction log. Because each tape stores only a portion of the database, it is less likely that a new tape will have to be mounted on a particular device.

Warning!   Do not dump the master database to multiple tape devices. When loading the master database from tape or other removable media, you cannot change volumes unless you have another SAP ASE that can respond to volume change messages.

You can use multiple devices to load a database or transaction log.

Using multiple devices decreases both the time required for the load and the likelihood of having to mount multiple tapes on a particular device.
