Understanding Overwrite vs Append
We are running 11d (7170, sp1) on Win 2003 Server Standard. We have two jobs running nightly, disk-to-disk and then clone-to-tape. My question is regarding the tape backups.
We have the tape job set to: Append to media, overwrite if no appendable media is available. We have overwrite protection set to 6 weeks and append set to Infinite-Allow append. We get "Please insert overwriteable media" errors for the tape jobs even though there are tapes in the library with room on them for the backup. If we import an overwriteable tape the job completes. All of the tapes in the library (before the import) are not overwriteable due to the 6 week limit.
My co-worker is insisting that Backup Exec is not working correctly. He is adament that job should use one of the tapes in the library to complete the job. I think that this is not right. I believe that if the tape is not overwriteable due to the Overwrite Protection period not having been reached, the tape will not allow appends or overwrites.
Who is correct? Do we have a problem (if so, it is most likely configuration and a mis-understanding of the overwrite/append concepts) or is BE acting correctly
Thanks for your help!
