So, if you want backups every day, you must have a tape for every day.

Sure, but it doesn't have to be a unique tape each day. Since amanda normally uses a holding area to spool to tape rather than spooling directly from the source directories, I just back up the holding area daily (to tapes HOLDING001 or HOLDING002), and when either of my two holding tapes almost fill up, I flush the holding disk to another tape set (DAILY001, DAILY002, etc).

Sometimes a single daily tape might end up holding 10 days worth of backups.
