Determining size of data to be backed up in a protection group RRS feed

  • Question

  • Hi Everyone,

    I would like to know if there is an easy way, a script, a cmdlet in order to know how much data would be backed up once a protection group is created by adding some data sources.

  • Hi,

    I'm not 100% sure what you are asking, but see if this is helpful.

    When you protect a data source (Exchange DB, SQL DB, Volume) DPM creates a replica volume and copies the protected data to that replica volume.  You need to plan your replica volume to account for growth of the protected data over time.  DPM also creates a recover point volume used to hold snapshots of the protected dats source - basically block level changes of the DB / files being protected and in the case of exchange a copy of the log files so we can restore the data to a previous point in time.   So the amount of data being backed up is dependent on the original data source size - plus the amount of data churn (changed / or new data) over time.  The storage calculators and technet links below will help you.
