Hello Forum,

Since I’m reconstructing everything I would like to seek some advices for WAN accelerators.

We have Primary Site (Austria, Vienna) and Secondary Site (Serbia, Novi Sad).

Backup to Primary:

• Backup Jobs going to Synology LUN that is connected via iSCSI to Windows Server (ReFS 64KB block size) + FastClone
• From Monday to Friday - Incrementals
• On Friday - Full Synthetic Backup
• 21:00 - 22:00 starting of the Backup Jobs

Backup to Secondary:

• I would like to try and implement WAN Accelerators for this so that potentially we have better performance.
• 2 Source WAN Accelerators. 1 for large VMs and 2 for small VMs
• 1 Target WAN Accelerator.

Question regarding Backup Copy Job:

• As I’ve read some documentation about WAN Accelerators I checked that Source WAN Acc should have better CPU performance so it doesnt need to be some high I/O performance device and for Target WAN Acc is opposite, is thsi true?
• Plan is then to use physical Windows Machine with SSD on Target WAN Accelerator
• How would I approach this Backup Copy job timing?
  • We already had it configured as “Intermediate Copying” and we didn’t have any problems with the network
  • Our Network is 1Gbps on both sites
• What would be the best option for Initial Seed?
  • It’s not possibly to transfer it physically because of different country at the moment

I would need a general best practices for this.
Don’t know how would it perform without WAN Acc to be honest.
