Thank you for your reply. Please clarify this for us:
For example: If I append to a media set forever, the media set will contain a large number of tapes. Some of the back jobs will span more than one tapes as below:
Jan tape1, tape2, tape3 overwrite
Feb tape3, tape4, tape5 append
Mar tape5, tape6, tape7 append
This is just an example. My monthly backup use up 9 tapes.
After 5 years, I would have 540 tapes in this media set. Does it mean that I will have to catalog all these 540 tapes just to restore a file (if the catalog ever blow up) ?
You are saying that I can just pick up a tape and catalog that tape only? The catalog job will probably give some error; but it should catalog and tell us what on that tape?
What if there is a disaster and I loose all the tapes except for a few tapes?
Thanks
