was there any resolution/clarity on this one ?
Have very similar issue with VEEAM, DD2500+Boost + Exchange restore
Have checked integration and best practice document (Veeam+EMC) and those should be in order...
In my case mount succeeds, but takes like 20+ hours.
When doing Backup directly to disk mount (staging area on primary storage) it takes ~5 minutes to mount.
Thanks for the help!
