Our tape backup drive failed last year and we're forced to go with an online backup solution. This was nice and easy to do but the backup times are HORRENDOUSLY slow, and I wouldn't want to deal with full system restore if ever needed.
I'd like to get away from the online backup solution, and 4 TB NAS drives are rather inexpensive (pay off in 2 years compared to carbonite's subscription). I liked tape because it's easy to take off site to protect it from fire/flood etc, but the NAS isn't exactly portable.
I could house the NAS across the street in another school connected with 10GB fiber. The NAS would be permanently stored there on the network (I suppose it would be susceptible to hacks/virus etc), but protected if the building with the primary data storage went up in flames...
Would this setup allow you to sleep at night if it was your only data backup?
