No backups took place, it just showed the first one failed and other servers were green still. I was incorrect on 3/4 of the protections running. What is the native capacity of the tape, and is it marked offsite ready ?Ĭheck out this blog and look for the device IO errors 0x8007045D in the DPM logs and also add the BusyRetr圜ount registry entry for your tape device. How much data was written to the tape for the three backups that succeeded. It ran the backups on three servers then failed on the 4th server.

Under this condition DPM can't perform the tape copy from the last full short term backup tape media to the new long term backup tape media because you need two functional tape drives to perform the tape The problem may come when the DPM server is using a single standalone tapeĭrive, or a tape library that is capable of having more than one tapeĭrive but only has a single (operational) tapeĭrive in the library. In summary long term protection to tape will always make a copy of your short term protection media, either the short term tape media, or the short Protection to tape will create a snapshot of the local DPM replica and backup to tape. If you have short term protection configured to backup to disk, the long term When it comes time to run the long term backup to tape,ĭPM will use the last full short term backup tape to make a COPY to another tape for long term protection.ĭPM will never try to backup data from the protected server for any long term backup jobs when you have short term protection configured, that is by design. When you have both Short term protection and Long term protection configured to backup to tape,ĭPM will use short term backup jobs to make a FULL back up of the data from the protected server to tape.

If tapes are not beeing freed up for the next weeks backups, please install this update and see issue 9.ĭescription of Update Rollup 2 for System Center 2012 OK, Short term backups and long term backups will each go on seperate tapes, so that is probably why the tapes are being used up. It should be more straight forward then that! Set-DPMGlobalProperty –DPMServerName -TapeWritePeriodRatio. But this doesn't make sense, why not just have it in the GUI? Then the article was making mentions of adding registry I need to get something going soon, i would appreciate any help. I have roughly 40hours into trying a bunch of things, i haveĮrased the groups over and over but still have issues. I see so much mix information out there leading me into so MANY directions. I saw some mentions of a command, but it doesn't work and i have a feeling this may have been DPM 2010? Not sure. To dig into any information on why the issue is happening. There is very little information on this and I have found it VERY difficult I'm running two protection groups with Co-location enabled and only one will run of the two now.
