Hi Avamar Community -

We are currently installing Avamar 7.3.1 with Data Domain 4500 (DDOS 5.7.2).  We were expecting to get fairly fast backups since we are on a multi 10G link (Cisco UCS 6248's uplink to Cisco 5K's (which traverse to the 7K for routing)) with the storage being EMC VMAX and Xtreme IO.  However, we are noticing VM image level backups (i.e. first full backups) taking an extensive window to backup. For example, we have a VM that has 4.75TB provisioned space but that is using 2.9TB of that space.  We had to cancel the backup job after 9 hours.  We did another VM level backup for a machine that has 4.4TB that is only using 1.3TB.  This VM level backup took 8.75 hours.  We did other tests outside of VMware (and the UCS chassis) and the initial backups are consistently slow. 

My ultimate questions is: what should we be expecting for backups?  What kind of throughput are yall getting (or have got) on your first initial backup?

Any information is appreciated.
