Is it possible to hook up an external HD (FireWire/USB) to a server while running other hard drives in a RAID so that I can use the external one to back up my web/db directories?
If possible what I want to do is do weekly backup to the external HD and then once a month go to the DC my server is located and swamp the external HD for another one and keep the one I just pulled at my office. Rinse and repeat once a month. Yes sounds kinda paranoid but I'll be getting a dedicated server and have no desire to deal with any user data loss. Having the customers wait a day or two for a restore I can deal with but not if I lose any data.
How about keeping a clone server with the exact same specs as my main hosting server which I update with the data from the backup drive and keep at my office. If the main one goes I just go into the dc and swamp it out for the clone.
