Server 2012R2 Data Dedup Results

Veeam Logoby bcscholl » Thu Apr 10, 2014 9:37 pm

Wondering if these results are as expected:

Backup Volume: 5.80 TB Capacity, 5.06 Free Space, 74% Deduplication Rate, 2.14 TB Deduplication Savings

Backing up 30 VMs within 5 Jobs totaling 3TB of data. All jobs Reversed Incremental and run nightly, dedupe-friendly compression, Local target Storage Optimization . All jobs have secondary Backup Copy Job associated to save 1 Week, 1 month, 1 quarter and 1 year. Backup Copy Job runs to its own backup repository on the same volume as the Backup Jobs.

Currently have 3 or 4 backups per VM and 1 for the first Backup Copy Job.

Two questions:

The Backup Repository is running over iSCSI but still local to the Veeam Server, any benefit using LAN Target?

The Backup Copy Job .vbk files all show 0 bytes on disk, but some are 490GB in size. Is this anything to be concerned about?

Thank you,

After further review I've figured of course the Copy Jobs are going to be 0 bytes on disk, they are copies and dedup is running. Still, amazing results.

We may decide to use another volume for the Backup Copy Jobs just to be safe.

Yes, keeping second copy of your backups on another media would be definitely a good decision.

In order to be on the safe side it still might be worth trying to perform restore procedure, using "0 bytes" .vbk file, and seeing whether everything works as expected. Thanks.
