Tape drives implement ECC much like memory. If you trust your memory you should trust your tape drive assuming you don't throw them around.

I was under the impressions that some sort of verify or sum check operation was done at write time and that if a status 0 was returned it was a pretty good indication backups would be able to be restored. Taking all physical factors aside ( e.g tapes being bashed around making them unusable ) the other way to verify is using bpverify but i'm just wondering if its needed. Anyone shed any light on this for me? I know the only sure fire way of knowing a backup is fine is performing a restore, but unless a full restore is done (which has its own problems of space etc) then what other assurances are there? Netbackup 5.0MP7, 6.0MP4 on a mixture of Solaris 9 and 10 Cheers _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
