Data Backup over slow WAN connection

Hi all,

Having to do backup of server over a slow WAN connection from Server to remote QNAP NAS. Any suggestions on what software to use? NAS has Rsync server app. Running Windows server 2012 R2. Link is around 1mbps. All data is around 16TB. Only around 10GB needs to be updated on average however finding that most software cannot compare fast enough to get through the 6 hour window that i have for backing up.

Any suggestions? Would prefer open source as this is a non profit so do not have lots of cash lying around. Must be able to schedule backups.

Thanks for your help!!

B.

Hi thanks for the info will check out code42 - as for bandwidth I can increase it to 4/6mb. Will investigate and revert

No worries. Bear in mind that you may have to crank it up higher. Also bear in mind the initial sync is going to be ugly - you're looking at 15 days or so assuming 100% of the link is available for backup... Crashplan has a dedupe engine that will help, but it's still going to take a significant chunk of time. Can you increase the WAN bandwidth to, say, 20Mb, for a week or so?
