NAS to NAS backup via internet

[Tombott]

We have a 2TB NAS at our home office and a matching unit at a branch office. We have about 75 GB of data files on the NAS. We copied all the files using a portable drive to the branch office NAS (12 hour download). Now we want to use a Vice-Versa profile to backup all of the new/modified files each night from the home office NAS to the branch office NAS. We were doing that procedure in the home office over the LAN and it ran fine. Now it will be via the internet and our tests are showing that it will take some time to complete the nightly updates. Both offices are connected using Watchguard firewall/routers with a constant VPN connection from the branch office Watchguard unit to the home office unit. Both offices have DSL connections with actual speeds of about 4500 kbps download and 500 kbps upload.

Our test profile is below. Are these settings the best for our setup in terms of speed via the internet connections? Any recommended changes?

Profile File: C:\Documents and Settings\Administrator\My Documents\ViceVersa PRO 2\bu lr ts to fay ts.test.fsf

Hi, the settings are good. Does it take long to scan the remote folders over VPN? thanks

A VERY long time. The compare takes 2 hours for the 76 GB. The backup did not work last night - partly due to my errors in listing the folders to back up in the profile. Partly due to connection drops.

I am trying again to get it set up and "catch up" on the new/modified files since the transfer via portable drive was done last week. Then I want to see if this set up is viable to keep up with our daily new/modified files. That can't be more than 1 or 2 GB/day at most.

This has been a very interesting experience.
