I have a 300GB RAID tower attached to a server via FireWire. Every night, the server pushes all its backups onto the tower for storage where they sit until they get deleted seven days later.
But I worry about this system a bit. If someone managed to get into the server, they could get into the RAID tower as well (it’s the F: drive — FireWire rules). Or what if a virus started executing by crawling the drives and deleting files? This means all my backups and archives would be vulnerable.
The fact is that the tower only needs to be connected to the server for about 30 minutes a day — the amount of time it takes to copy 20GB or so of stuff to it. The other 23.5 hours, it’s doing nothing.
This being the case, does anyone make an air gap device with a timer? I’d like to have some mechanical device that physically connects the tower to the server at 12:45 a.m. so it’s ready for the copy job at 1:00 a.m. then disconnects it about 45 minutes later, when everything is copied over.
Thus, if my server is compromised at 4 a.m., there’s no F: drive for anyone to poke around in. The tower would be separated from the server by a one-inch gap of air. That’d be pretty flippin’ secure, especially since the device would be standalone — a little gizmo unconnected to any computer or networked device.
Does anyone make anything like this? Truth be told, I’m not that paranoid, but I’m just curious if this exists.
