When you backup the primary storage pool to the copy storage pool, it will
read the primary pool tape. In the event the primary tape is bad, you'll
get a bunch of errors in the activity log.

Subject: Tape backup verification
Hello everyone,
I have some questions about backup verification and would like to seek
some
advice.
When I backup using TSM, how can I verify that the backup is good ? What
I
mean is when TSM write to tape, how do I verify that the write-to-tape
process is good. I come from VMS backup. In VMS, it has a command:
BACKUP
/VERIFY, which will write the file to tape, rewind the tape and read the
backup file. This will ensure that the file I wrote to the tape is good.
The disadvantage is backup time is much longer. How does TSM do backup
verification ? By checksum, by rewind and read ? Is it possible to
specifiy the verification method ?
Regards
