Tape Co-location (using lot of tapes) RRS feed

  • Question

  • I am a new user of DPM and using DPM 2012, having trouble to co-locate more than one protection group in one tape. I created co-location on tape and include four protection groups in co-location PG set. Although all protection group retention is same but still I unchecked "Don't allow backup of different retention periods......" but when I go to advance I read some article which say's need to set some value in write protection and expiry tolerance. I am not sure what should I put here but based on some recommendations from different forums I put 14 / 14 for both fields.

    All protection group is running weekly backup, which suppose to be start every Wednesday until all job completed. we take out all tapes from library every Tuesday to send offsite but unfortunately for some reason it seems to be co-location on tape not working and it is using lot of tapes and every protection group is using separate tapes.

    Can any body help me out to resolve this issue. 

    Thanks
