  • Hi,

     

    Yes, in both cases, if you configure the PG's to use 2 tapes that is called drive pooling.

    Drive pooling - If the user specifies "drives allocated" as > 1 while creating the protection group, the data sources will be split across tapes. For e.g., 5 data sources and drive max limit set to 2 may write 3 data sources on one tape and 2 data sources on another tape. Depending on the size of the datasources, other ongoing scheduled backup jobs to tape in other protection groups, and the number of tape drives available at the time, you may find an uneven distribution of datasources going to the various tapes.

  • Hi Don,

    The guidance we're giving customers is if the library is listed on the Windows server catalog under the hardware / storage section, then it should work fine with DPM.

    Leverage the DPM 2007 compatibilty list, anything on this list should work on DPM2010 if they have Windows 2008 X64 drivers.

    Sorry I can't help you with the performance part of this question....

  • Thanks Mike,

     

    We are using DPM to backup our enterprise data and DPM is fitting the bill so to speak quite nicely.  The challenge we have is getting the data offsit.   Replication Bandwidth is too expensive for us.  We are looking at backing up to tape devices and are looking at the above mentioned Autoloaders.

    The above Autoloader can be stocked with two tape drives.  Can you tell me if DPM will utilize both tape drives simulataneously given the following scerios:

     

    1) There are many Protection Groups with Long Term Protection with Tape colocation turned on with the same retention policies etc

    2) There is a single Protection Group
