I plan to use copy as backup, because second server will be old physical computer(about 2TB disk) in remote office and first server will be virtual machine on storage. On first server i plan to have one folder where i plan to copy over rsync all files from second server.
That plan will work, but it won't protect against things like accidental deletions or overwriting important files that aren't noticed until after the next rsync run wipes out your copy. Backuppc or a similar backup framework can keep a history of copies online and cover both scenarios. Backuppc is particularly nice in that it's compression and pooling makes it not use a lot of space for the history and it provides a web interface for browsing the backups and restoring - and you can download files directly from the browser if you want. 2TB is a lot to copy remotely, though. You may want to use some other means to get the initial copy over - like copying to an external drive. Once the first copy is in place rsync will only need to copy the changes.
