Nothing is wrong that I see. It is a very typical result.
Amanda does not try to fill each tape to its full capacity.
Your report says there were 9 DLEs (Disk List Entries) dumped.
Six DLEs were dumped at level 0 (full dumps) and 3 were incremental, level 1's.
Total amount of data dumped from disk was 6.9 GB (Orig Size).
Most of that (6.76 GB) came from the level 0 dumps.
Those 6.9 GB of data were very compressible (you must be using gzip) and
were shrunk to only 1.9GB (Output Size).
Of those 1.9 GB, 1.9 GB were able to be written to tape (Tape Size).
Looks pretty good to me :))
