You can test a restore by performing a restore that reads the tape, but does not write to the storage system.
About this task
You can do a test restore in the following situations:
- To verify a backup tape that is old and might have deteriorated
- To verify that the set of tapes you have is complete
- To verify a backup tape that you believe was not written properly
- To quickly ensure that a block size works, if the block size is unknown
Note: Because a test restore depends on the speed of reading from tape, it takes almost the same time as an actual restore.
