I would build your own, but I did some research on this idea last
month, so a few facts for you:
http://www.rsync.net/products/index.html should have a 2 TB offering.
$0.64/GB for over a TB per their pricesheet. ie. $1280/month for your 2 TB.
I ended up using dreamhost.com. They are only $20/month for a
supposed 350GB storage facility. But I find I get the below speeds
making the 350GB unrealistic to really use (for me anyway).
rsync transfer rate 1 GB/hr (My T-1 maybe the limiting factor?)
rsync non-transfer rate 30 GB/hr. (ie. If I have zero delta's it
takes this long to verify it.)
I have been using the rsync --max_size flag to send more and more data
each night. (I'm trying not to overload their systems during daytime
hours when they seem to be busier) I should have my full 45GB
mirrored there in the next couple days.
If I ever have to do a restore it appears it should take a couple days
to pull it all back. At 1 GB/hr a 2 TB server would take almost 3
months to restore from a site like that.
OTOH, if you own the remote server and can Fed-Ex the drives around
you can do it overnight.
Also, If you decide to build your own server, then I would recommend
Rdiff-backup as a good backup solution. It uses the network
efficiency of rsync to implement a traditional multiple point in time
backup strategy. Specifically it keeps a copy of the current files
offsite and a series of deltas to let you get to historical versions.
Definitely the best offsite backup software I have used yet. (If is
CLI only as far as I know.)
