Specifying the blocking factor during restore

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.

Steps

  1. To specify the blocking factor, use the b option in the restore command line.
  2. Include the blocking factor as a parameter to that option.

Example

The following command restores a backup and puts it in the /vol/destination volume:

restore rfb rst0a 63 /vol/destination

The following list describes the elements of the command line:
r
Performs a full restore.
f
Specifies that a tape device is supplied in the command line.
b
Specifies that a blocking factor is supplied in the command line.
rst0a
The tape device.
63
The blocking factor.
/vol/destination
The restore destination.
