Re: DP backup exceeds the volumes size

Can you share more about what settings you are using for the backup application? Do you use compression and/or deduplication on these volumes? If so, your backup data might use the inflated data and not the deduplicated data.

You can use "Get-DedupVolume -Volume <drive letter> | fl *" in PowerShell and then have a look at the UnoptimizedSize property to estimate the needed capacity. 

Cheers.
