Media Expiration Dates
Its the novice again. In my policies I have set the weekly schedule having a retention set to infinity (level 5) - FIGURE 1.
I use vault to expire the images. I have set the retention level on tape to 5 Weeks (level 2) - FIGURE 2.
I started my weekly (full) backup on Jan 18. When I click on the Media under Media and Device Management in the NetBackup Administration Console, the Time Assigned dates do not correspond to the Date Expiration dates taking into account the 5 weeks retention period - FIGURE 3
How does NetBackup calculate the 5 week period? Please see attached screen shots. Thanks
I agree with Martin - expiration date is calculate from backup start date.
Please bear in mind that you have more than one backup image on your tapes. Have another look at nbemmcmd output for KW6554:
Images: 15
So here the 'Last Written' date will correspond with the start time of last image written to tape.
What I am trying to do is to calculate the expiration date for my tapes...
Just keep an eye on 'Tape Summary' report.
Run this report on a regular basis with 'Verbose' option selected.
