Over the holidays, our server ran out of space. We have a Windows2003 server with 3 physical SCSI drives (several partitions), and we need to expand our storage capacity, quickly.
Our system has been backing up onto an HP Ultrium tape drive, and every night we take 1 tape off-site in case of catastrophe in the building.
Initially we wanted to add a NAS-box connected to the network directly, which in addition to expanding our storage would take some traffic off the server: we would move all our large artwork files onto the NAS and hope to see higher speeds accessing data files on the server.
Our problem is that we cannot back up 100 GB of data over the network onto the tape drive on a nightly basis - by my math, that would take anywhere between 20 and 40 hours.
I've been looking into NAS-boxes that support hot-swapping, thinking that we could use several mirrored drives in the same way we've been using tapes (remove 1 drive on alternate nights and leave it off site), but I'm concerned that this would cause added stress and wear on the enclosure or the drives.
Can anyone recommend the best (read most cost-effective) way to solve our problem? We need more space, and we need it fast!
