Use the Review Disk Allocation page of the Create New Protection Group Wizard to review and change the space allocations on the storage pool for the replicas and recovery points that DPM recommends for the protection group. Space is also allocated on protected file servers and workstations for the change journal.

We recommend that you accept the default space allocations that DPM recommends unless you are certain that they do not meet your needs. Overriding the default allocations can result in allocation of too little or too much space. For information about how DPM allocates disk space, in the DPM Planning Guide, see Allocating Space for Protection Groups (

This page contains the elements described in the following table.

Collocate data in DPM Storage Pool

Select this check box for co-locating data to enable DPM to protect more number of data sources per replica volume.

Automatically grow volumes

Select this check box to automatically allocate volumes when more disk space is required for protecting the selected data source for the specified retention range. DPM automatically grows the volumes by 25% when the used disk space is more than 90%.
