The blocking factor specifies the number of tape blocks that are transferred in each write operation. A tape block is 1 kilobyte of data. When you restore, you must use the same blocking factor that you used for the backup. The default blocking factor is 63.
- To specify the blocking factor, use the b option in the restore command line.
- Include the blocking factor as a parameter to that option.
