EXCHANGE 2010 DAG

I am getting below error on my DAG database back up failures:

we can see that the CommVault operation is failing because it is unable to locate the shadow for the DB during backup.

 At the same time we can see Windows report that Volsnap purged the shadow due to the imposed limit on the volume.

 Description:
 The shadow copies of volume D:\dagmb02.db11 were aborted because the shadow copy storage could not grow due to a user imposed limit.

 Checking the D:\dagmb.o2 volume, we can see there is a 1024 MB limit imposed. You are going to see about getting this increased.
