Tape optimization doesn't work in DPM 2012 RRS feed

  • Question

  • Hi everybody,

    One of our customers runs DPM 2012 SP1 rollup 2 on a Windows Server 2008 R2 server. Tape optimization worked fine before upgrading to DPM 2012, but now 8 tapes (LTO5) are used for a full backup instead of 3 tapes before the upgrade. I created a set for tape optimization, and all Protection Groups are members here. The "don't allow backups of different retention periods to co-locate on same tape" check box is not selected. The write period setting is currently set to 4 days, and the tape jobs takes about 2 days to complete. All tapes are marked as Offsite ready.

    Data compression is currently disabled - recommended setting?
