Question: Why is my job not appending data to my tapes?
#5 Your 2nd (3rd, 4th, ...) job does not specify the media set that the tape already belongs to
i have be 2012 what i need to see there??
Number 4 of this article basically solved 3 months of overwrtire / append headaches for me. I could not understand why my backups failed continuously even if theoretically everything was fine.
Thanks a lot!
Hello,
Please see the technotes as additional information:
An explanation of the "Overwrite Protection Period" and the "Append Period"

Thanks
I had a hard time getting my backup to append to a tape. It was still in the robotic library but marked "Export Pending" (seen in tape details). Exporting the tape and importing it back in did the trick.
Hi - does item 4):
"When a job is running, the tape is marked as unappendable because the end-of-file marker is not written. If a job starts while the first job is running, then it will not be able to find an appendable media. It will then switch to overwrite mode, if the job property is set to "Append, overwrite if if no appendable media is available", or it will fail if it is set to "Append, terminate job if no appendable media is available". For the first append option even when the job finally finishes waiting and start, it will use an overwriteable media and will not switch back to the append mode."
...also apply to duplication jobs ?
In my environment we have B2D2T, all backups are saved to eight disk storage areas, each with max two jobs - so I can 16 backups running - thus there can be many backups completing, all of which have an immediate duplication stage - but I only have two target tape drives for duplications - which leads on to many duplications waiting (which I'm ok with).
Please could someone re-explain point 4) above - but in terms of duplication jobs?
Thanks.
I know I m answers a comment from a few months ago, however as it was not answered and for benefit of others:
The tape allocation (decision making for using append vs Overwrite) is the same for both backup and duplication jobs
Also in all cases once backup Exec switches a job from looking for an Appendable Tape to looking for an Overwriteable Tape, the job will not swicth back tp looking for append.
