We are currently evaluating Nutanix and also HYCU for backup. So far HYCU looks really good running on my CE lab server but there is one issue that they cannot answer to. For file restores on older recovery points (past the "Fast Restore" point), HYCU must copy the entire VM from the storage target and mount it to even start the search for a file. While for small VM's this my not be a big deal, larger VM's would cause a wait time based on your network connection to the storage target. For anyone using HYCU is this a concern to you? I'm very interested in hearing real world feed back here. Thanks!

we ran into the exact same issue in our production environment: Restoring a multi-Terabyte Exchange VM took many hours while cluster overall performance (we use entry-level 1000-NX series hardware) was clearly affected by sustained bulk writes.
We simply decided to keep more Fast Restore points (i.e. cluster based snapshots), reaching further into the past. Storagewise this workaround should not be a big deal, although there is no way to see how large those snaphots actually are.
I'm very confident the folks at Hycu will eventually establish a solution for this.
