the remaining 4 disks are locked in a fireproof safe at all times.
I’ve designed a pretty robust infrastructure to cope with the most ‘common’ incidents (deleted files/objects, knackered disks, blown motherboard taking out entire server).
One great feature of W2K8 is the bare-metal recovery!
It comes down entirely to how much the management want to spend – it’s a risk – spend £10,000 and you could get an all-singing, all-dancing offsite mirrored data structure. Spend £50 and you have one USB external disk. They need to factor in downtime (i.e. staff not operational) during recovery, and how much their data is worth (in case of complete non-recovery).
IIRC the upgrade from Tape -> eSATA disk was around £800 for everything, including software licenses (back in April 2010). Damn cheap, considering tape devices cost £1000+ these days! Plus the cost of tapes!!
Now we’ve grown as a company, and thus the management consider our IT infrastructure to be higher on the budget list.
Even building your own NAS can be very cheap these days, for nightly backups.
