Amanda doesn't really want to work that way. Amanda tries to schedule
backups such that approximately the same amount of tape is used every
night. To that end amanda will juggle the schedule around, with the
only real constraint being that everything gets a level 0 backup at
some point in dumpcycle days. Because of this, I and many others are
backing up fairly large systems in terms of total disk space, with
small tapes, in my case a measly DDS2 is doing:
[amanda@coyote tmp]$ df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda7 30237928 10164536 18537380 36% /
/dev/hda1 247919 103353 131766 44% /boot

/dev/hda6 4031656 925920 2900940 25% /home

//gene.coyote.den/dlds
1028080 338464 689616 33% /mnt/dlds
Or in the neighborhood of 60Gb of total data, all going into 8 DDS2
tapes in the space of an 8 day dumpcycle.
One can rig scripts and such around amanda to make amanda do that, but
its crippling/defeating the basic design of amanda to do so. You
will also need a drive capable of taking the whole system as a level
0 in one swell foop. Bring money, lots of it, for both the drive,
and the tapes... My DDS2's are 2-3 bucks each on ebay.
But, IIRC when you have to do a restore/recover, the programs will
take your input as to what you want to restore, amanda will search
her database, and tell you what tapes she will need in the order they
should be fed to the drive.

hdb1 is probably a device name, not a mountpoint. Use mountpoints,
just as you would to do an ls -l /home/amanda

You changed the name of the target from hd1 to hc1 which may confuse
amanda. And of course the directory tree /backup1/amanda must exist,
and belong to (usually) amanda:disk
