I have about 850GB of data for 60 employees here in Los Angeles on a Dell R700 (Windows Server 2003). We have 100mb up/down through fiber. We don't come close to using it, but we have it.
San Francisco field office with 1 employee - I just installed cable internet with 20/5 guarantee. The one employee there VPN's in as I don't have a server there, but would be willing to buy a cheap one if its part of the solution. I have plenty of old dell desktops around that I could install linux on also, but they couldn't VPN in i don't think.
I backup currently using free software called Cobain Backup. I do a full backup on the weekend, and then incremental on the weekdays - and its to an external 3TB hard drive via USB3.0, and its quick and I swap out drives every other week and store off-site (my kitchen cabinet...yep!).
I want to be able to do a rsync style backup from LA office to our field office, but NO clue how to go about it, since I rarely go up there for maintenance (again - only 1 employee). Our router here is a Cisco and use cisco vpn software to get in.
On any given night, only a fraction of our files change, but of the 850GB, about 65GB is email that does change and gets backed up. With the speed we have, that shouldn't be a problem, BUT i could leave that out of the nightly backup to SF.
I think the ee community is brilliant, so i can't wait for answers... (i am rubbing my hands together in anticipation ... help me please!!!)
