  • Hi,

    The most accurate way to know how large your BMR backup will be for each server is to follow the below procedure.

    1) Set up a network share on a remote machine \\server\bmrshare

    2) From an administrative command prompt on the Protected Server, type:

                  wbadmin.exe start backup -allcritical -backuptarget:\\server\bmrshare

    At this point, it will list the volumes included in the BMR backup, press Yes to continue.

    3) When the backup completes, see how large the backup is on the BMRShare.

    Then as per the technet article: http://technet.microsoft.com/en-us/library/ff399599.aspx

    Replica volume calculation.

    For system state:

    • (Data source size x 3) / 2

    Recovery point calculation.

    For system state:

    • (Data source size x  retention range in days x 2) / 100 + 1600 MB
