DPM Protection Groups RRS feed

  • Question

  • We are getting into using DPM2010 to backup our servers. Ive got the server installed an im wondering about the best way to lay out protection groups.

    I have:

    1 exchange server

    1 domain controller

    1 file server

    would it be best to backup all 3 in one protection group or better to create a seperate protection group for each....or maybe a seperate group for exchange and keep the other 2 in their own group.

    Is there any benefit to making more than 1 or lumping them all together other than setting frequency of backup and protection times?

     

    Thanks

  • Hello,

    I personally would keep them in separate protection groups and stagger the synchronization times for performance reasons.

  • Protection Groups are all about retention goals.  If you have different retention goals for different servers, put them in separate protection groups. Otherwise you can leave them in one.

    You can rearrange things later if you need to. Your decision now is not permanent.

  • Hi,

    What you need to think about is that DPM is a data protection program.

    So you need to create the following

    1. a PG-Data (Protection Group) to protect your data. That includes file servers and volume that only contains data. If the data change alot during the day you might want to sync more often (1,2 or even 4 hours).

    2. PG-C Another group to protect the C partition if there are some files that you need to protect their.

    3. PG- Exchange: this group is going to backup only exchange DB. if you send and recieve alot of emails and the transaction logs are getting big in short time then run the sync more often that will help you truncate trunsaction logs.

    4. PG-System state: This is a special group to protect the syste state of your servers.

    If you have SQL then create another PG.

     

    Make sure that the system state and the C will not run at the same time. make sure that each Express Backup will be completed and then the other job will start. That to not overload yout network as well your servers.

     

    If that helps. Please mark it as Answer!

    Laith.
