You should really (!) buy at least a second one.
As stated in my copy of the FAQ:
Q: What if my tape unit uses expensive tapes, and I don't want to use
one tape per day? Can't Amanda append to tapes?
A: It can't, and this is good. Tape drives and OS drivers are
(in)famous for rewinding tapes at unexpected times, without telling
the program that's writing to them. If you have a month's worth of
backups in that tape, you really don't want them to be overwritten, so
Amanda has taken the safe approach of requiring tapes to be written
from the beginning on every run.
This can be wasteful, specially if you have a small amount of data
to back up, but expensive large-capacity tapes. One possible approach
is to run amdump with tapes only, say once a week, to perform full
backups, and run it without tape on the other days, so that it
performs incremental backups and stores them in the holding disk.
Once or twice a week, you flush all backups in the holding disk to a
single tape.
And you could even run the level 0 without tape and always flushing your
backups, assuming you have enough space for a full week of backup.
Try this ( or similar)
dumpcycle 7
runspercycle 5
tapecycle <what-you-have>
# with reserve 100 she will always degrade the level 0's
reserve 30
