We have a Windows 2012 file server that is a VM hosted on VMware. The file server has iSCSI LUNS direct to Nimble Storage Volumes and have installed the Veeam Agent for Windows version 2.0 for backup.
The backup agent is working, but were getting de-duplication of 1.2x on Volume level backup. Our test backup consists of 2 volumes and 1.1TB of files, like user home directories and department shares. Were planning on doing a weekly full backup and daily incremental, this one server hosts about 6TB of data to backup. We typically see > 2.x for block level backups in a normal backup job.
Here is our configuration (Full Backup):
Compression Level: Optimal
Storage Optimization: LAN Target
Transferred: 964.6GB (1.2x)
Backup storage is a Synology Rackstation with 10Gbps interface.
I contacted technical support, they had me change Compression to Dedupe-friendly and Optimization to WAN target. Using these settings there was absolutely no savings on the backup size, Processed 1.1TB, Read 1.1TB and Transferred 1.1TB.
Anyone else experience the same de-dupelication for file backup? What about Exchange backup with the agent?
