I will try an answer your questions as best as I can…
See A for my answers:
Hello,
Your current media rotation scheme causes backup exec to run out of overwritable media each Tuesday.
Whan a job is submitted to backup exec:
1. It checks whether the job is set to overwrite the tapes or to append to them. Accordingly it will check for overwritable/Appendable tape in the targetted media set, if none is present here it checks either for scratch or recyclable media(Check the technotes provided for definition).
A. This is set to ‘append’. In the Media bar - Tuesday’s set sits in ‘retired media’ – is there a reason why it’s done this on two brand new tapes?
Media Overwrite Protection in Tools\Options\Backup is set to:
‘Append to media, Overwrite if no appendable media is available
2. The search will depend on the setting made in Tool>Options> Media management. Overwrite recyclable media first or overwrite scratch media first.
A. ‘retired media’ as suggested so does this apply to me?
3. When Backup Exec comes across several media in the desired category it goes for the oldest overwritable media available.
A. Would it be feasible for me to delete the contents of the Retired Media?
4. After this entire operation if still no overwritable media is found backup exec displays an alert for the operator to insert an overwritable media(This is what is happening in your case)
A. Correct
5. If operator fails to provide the overwritable media the job fails with the error that you have.
A. This is set to ‘overwrite media’ in Tuesdays Device and Media properties.
6. In order to avoid this situtation, check the number of media sets you have and the OPP and AP set on these media sets. Create and configure the media sets and their OPP and AP according to your requirements, so that each job has sufficient media to complete.
A. OPP set to NONE, AP set to ‘Infinite – Allow APPEND’
OPP is grayed out however I can change the AP.
The way our tape rotation works is set to full backups everyday.
Mon,Tues,Wed,Thurs (Fri 1)
Mon,Tues,Wed,Thurs (Fri 2)
Mon,Tues,Wed,Thurs (Fri 3)
Mon,Tues,Wed,Thurs (Fri 4 kept stored away for a year.)
We have had Veritas software since last year, Summer 2004 and have never had this problem until the last 2 months. So I ask why now?
7. To better understand media management please refer the media management chapter in backup exec admin guide. and the following two technotes:
http://support.veritas.com/docs/237374
http://support.veritas.com/docs/192265
admin guide:
http://support.veritas.com/docs/266190
A. I have read 237374 and 192265 and happy with the information, with regards to the Admin Guide there is too much information to consume and I don’t understand why it would do this suddenly. All I want is instructions of how to get it back up and running.
Let me know what specific information you require?
