DPM 2010 - How does DPM handle old data on replica and recovery volumes? RRS feed

  • Question

  • Hey,  I am looking to deploy a DPM 2010 Backup server and have several questions as I am trying out the trial.  Your help would be greatly appreciated.

     

    1. Does DPM automatically delete data from the replica volume if that data has been moved or deleted from the protected file server?  If so, when does it do this and how frequently?

     

    2. Similarly, does DPM delete recovery point data older then 30 days (retention period)?  If so, when does it do this and how frequently?

  • Hi,

    1. Yes, any data changes that occur (files added / modified / deleted) on the protected volume get applied to the DPM replica volume during each synchronization.  So if you Synch every 30 minutes, those changes will be applied to the DPM replica volume every 30 minutes.

    2.  You configure a retention period at the time you create a protection group.  If you choose 30 days retension, then every night at midnight, DPM will remove the earliest RP older than 30 days.   RP's are not based on calendar days, but rather days that have a successful backups, so if you don't backup on Saturday and Sunday, then those two days won't be counted. Likewise, if the server was down for maintanace for a day or more, then those days won't be counted toward the 30 days retention range.
