Well, for those requirements you better go with third-mirror / split-mirror type of technologies. I wouldn't bet on snapshots in this case (or maybe it's just wording and that what you meant). Recently, we've implemented EMC BCV backups of couple 1 TB databases and they work like a charm - 4 times a day having a backup - dream of any DBA! :) Plus daily off-host backups to tape.

In cases where you have really extreme backup requirements (e.g., terabyte+ database running flat-out 24x7 on the biggest hardware you can find) snapshot technologies can be a godsend. They might be the only option available.
