strange dpm problem

[maark]

Struggling with this one so appealing to edugeek.

Setup:server 2008 R2 with system center dpm 2012 - everything patched up to latest versions.

Using filestreamer as tape library in dpm.

 

Have installed protection agent on server 2012 file server all ok and protecting several folders of staff/student/shared data with protection group.

No errors in dpm or firestreamer and dpm say protection ok after i forced creation of protection point.

However it only does about 25GB of backup when I have about 900GB of data in them folders. though reports completed ok.

When I go to do a test recovery of a file it lists all the files on them folders and I can select a file to recover. I can recover a file to original location or a local location on dpm server and it reports recovery ok. When I go to open the file it won't open - e.g. a pdf says not supported filetype or damaged.

Looking at recovered file - says file is 1.24MB but size on disk is only 4kb. Have tried recovering several files - they all have size on disk of 4KB and won't open.

 

Can anyone give me a pointer to whats going on as no error messages there to give me a clue - dpm reports everything ok!

Do you have dedup enabled on the 2012 fileserver? I had the exact same issue while migrating from DPM 2010 to 2012. DPM 2012 sp1 + CU2 cured the issue for me.

I do have depup enabled - will check updates - though I had patched it up to latest but so hard to find a proper link to service packs and updates for dpm 2012 - keeps pointing you to cloud evaluation software site. Thanks for help.

This link may help, it provides a list of DPM version numbers so you can see where you are with services packs and CU's

I don't know about 2012 or dedup, but have plenty of experience of 2010. If I were you I would schedule a full consistency check on all your protected sources as soon as possible, as it sounds like one or more of your replicas are corrupt.

update - this works ok after updating to system center 2012 dpm service pack 1 - so obviously some issue with earlier version and server 2012 with dedup enabled.
