Hello there,
I have an DPM 2010 environment where i am using IBM LTO tape library with 24 Cartridge and 2 TB of internal disk. I have a schedule backup of data server which has around 700 GB data and exchange server which has around 500 GB database. Exchange is in DAG environment so i can't backup it directly to tape. So, how much space do i exactly have to allocated for exchange to backup and what should be the retention period by DPM.
Regards, Ishuv
