Can Netbackup overwrite only parts of a tape
Hello,
I have my backups on mixed retention tapes. Can Netbackup overwrite only the expired parts of the tape, or does it wait for the whole images on that tape to expire before it can reuse it?
Would you guys please point me to where this is documented.
Thanks
it does not...
it wait untill the last images on the tape expires and then start reuse it..
that is the reason the best parctice is not to mix the mulitple retenctions in the single tape.
have a look into the below discussion
