[Techtalk] seeking backup solution recommendations

[Conor Daly]

The big advantage of tapes is that you can archive them in a fire-safe, take
copies offsite and, if your dataset grows, just add more tapes.  

The big disadvantage of tapes is that you have to manage a growing
collection of tapes, refrest your tapes, move them to later formats and tape
drives are expensive.

They're still well worth it at work / enterprise.  Less so for home use...
