If you have to comply with SOX or other auditing requirements and need
different media for each day of a month, disk based backups are more
expensive than tape based solutions.

There is more to this than cost alone, but ... we switched to disk based backups because it worked out significantly cheaper than tape. This decision was taken a few years back so I forget the exact costings but it was something along the lines of removable disk drives (now use USB but didn't then) were about double the cost of the tapes we were looking at but the tape drives themselves were very expensive. Putting it all together and disk worked out significantly cheaper (and there were other advantages besides). Obviously it does depend on how many disks you need - we only rotate our backups off site weekly and keep backups for a month. If we did it daily and significantly increased our retention period then there would logically come a point where tape would be cheaper.

Ultimatly, whatever backup system is used its vital to be confident that you can successfully restore from it.
