DPM 1801 backup to VTL on DR4100 failing at 2TB everytime! RRS feed

  • Question

  • I just stood up my first DPM server running 1801 on a VMware VM, the OS is Server 2016 and SQL 2016 is installed locally. After adding a SAN drive for short term protection, I added a DR4100 dedup appliance as a Virtual Tape Library using the instructions found in the PDF that is linked below.

    Backups to the VTL have been working perfectly until I tried to back up a 5TB folder on a Server 2012 R2 VM. I have tried to create a recovery point 3 times and each time it fails after transferring 2.04TBs of data. I have pasted the error shown in the console below and it is followed 8 hours later by a "DPM failed to write to tape because the tape is write-protected. (ID 30104 Details: The media is write protected (0x80070013))" error, not sure if this second error is related. Anybody seen this before?

    Type: Tape backup 
    Status: Failed

  • housekeeping - closing post.

    Best to work with the VTL vendor for those errors - DPM is the victim of hardware related errors.
