Surebackup/App item restore on dedupe storage appliance

Post by makcy »

We have tested few different appliances recently and found that application item (exchange) restore extremely slow when VEEAM tried to mount the edbs. It can simply take up to 3 hours just to restore a single .msg file.
Also, the Surebackup failed if we stick with the default 10 minutes startup timeout setting. There is only 1 out of 3 appliance able to have it done when we change it to 20 minutes.

These backup appliance are all secondary storage with dedupe feature - HP StoreOnce, EMC DD, Quantum DXi. And we are going to test with Exagrid very soon.

Is there anyway we can overcome these performance drawback on secondary storage? How does the job configuration impact on these issue?
Is is normal that it is going to take longer time to complete the Surebackup and application item restore when forward incremental restore points increased?

Typically, you are not able to get good performance while running SureBackup or application item-level restores from deduplicating storage (unless it does post-process dedupe and has landing zone, like Exagrid). Dedupe appliances are not designed to handle random read workloads and are best used for long term data archival, so backing up directly to them is not inline with our reference architecture. Thanks.
