To restore the database, you must have the database backup
volumes. The database backup volumes can be full, incremental, or
snapshot.
About this task
For database restore operations, the
Tivoli® Storage
Manager server reads
the information that is in the volume history file to determine the
number of data streams to read. The server attempts to match the number
of streams that were used during the backup operation. For example,
if the backup operation used four streams, the
Tivoli Storage
Manager server attempts
the restore operation using four streams.
If you reduce the number
of data streams after a database backup operation, this information
will not be available to the server when the database is restored.
To specify fewer data streams for the restore operation, take one
or both of the following actions in the device configuration file:
- Reduce the number of online and usable drive definitions by removing DEFINE
DRIVE commands.
- Update the value of the MOUNTLIMIT parameter
of the DEFINE DEVCLASS command.
