  • Hi,

    A recovery point is a "point in time" snapshot of a protected data source that can be recovered using DPM Console Recovery tab.

    A recovery point is taken at specific user defined intervals and / or times.  An Express Full backup is a recovery point and is associated with data sources like Sharepoint, SQL dabases, and Exchange databases.  Express full backups bring over block level changes associated with databases and apply those changes to the Replica copy, then DPM makes a recovery point.    Synchronizations for databases like SQL and Exchange are also recovery points but they are incremental backups. Only log changes are brought over and stored on the replica during a synch, and that too is considered a recoveyr point.   Synchronizations for NTFS volumes, file or share protection are not recovery points, those synchronizations simply bring over block level changes to protected files and apply them to the replica copy.  You specify when and how many recovery points you want for file based data sources.   

    The type of data sources you have in a protection group will dictate what kind of options you have for Sync, recovery point, and express full options while going through the protection group wizard.

    Your service level agreement (SLA) will dictate how often to make recovery points and for how long to keep them.

    Hope this helps.
