ok, budget constraint are "cheap as possible". Importance of backups is quite important but the end of every day, taking something offsite would suffice. I was thinking of something like getting 2x NAS drives and swapping over every other day - taking one home each night. And, the NAS drive can sit on my desk each day.
I was also looking at the Synology DS-101G+ Diskstation - 6in1 Server (w/o HDD SATA) File/Backup/Printer/FTP/Photo/Web Server. This is on SCAN todayonly at the moment - also comes with software to backup SBS2003. Maybe I can get 2 of these? Anyone used them before?
