DPM 2012 - Backup Protection Group to Tape

Update 2014-03-18: It appears there's been quite a few more revisions by Wilson, now version 1.6, since I first posted his version 1.0. I've updated the list below to reflect that latest version.

We've had a few instances where a backup job (long term to tape) fails. When we try to resume the backups by selecting "Resume tape backups...", it causes every data source in the protection group to backup to individual tapes rather than consolidating the backups onto one-tape (as it normally does on the scheduled jobs.)

We found this powershell script posted by from Mike Jacquet that works great to overcome the multiple tape issue! http://social.technet.microsoft.com/Forums/en-US/dpmtapebackuprecovery/thread/4fafbcb0-ac2c-4867-8434-31f1f5e532e0/#7b40ef6e-d8bd-4a24-aecd-5f1605e80225

After modifying it to work with DPM 2012 by adjusting line 25 to DPM 2012's SQL instance, $instance = '.\msdpm2012', we were able to run it to re-trigger one of our failed weekly tape backup. Hopefully this post will be a bit easier to find - but credit still goes to Mike and Wilson, I'm only the messenger. We did notice that you need to be sure and inactivate any alerts that are still active and it takes a minute or two to see the jobs kick off.

Given the Microsoft uneccesary complexity found in DPM for such a simple task as "Trigger this tape backup Now!", Justin's script is a Life Saver.

Thanks and Congratulations for a Job Well Done!

Justin Bennett said...

It is really Wilson Souza who deserves the praise. Just had to use his script again yesterday.

Great work. Just used the script to trigger yearly backup, because i had problems with scheduled job "not doing anything".

It must have to do something with this (response from another forum):

"Due to the way SQL Scheduler behaves, creating a monthly or a yearly backup
via DPM to start for a time within 24 hours from scheduling time, leads to
backups getting moved out by a month and year respectively." - ???

Whatever... Thank you very much.

Thanks! The Access Manager service stopped over the weekend and I had to re-run all the weekly tape jobs.

I also found 2 groups that had an extra monthly tape job. Great script and good work!!!

Excellent, thank you.
