True. First time I tried a backup of 80 MB of text files. Worked.
Next I tried an 80 MB disk filled with Text files compressed with
DiskDoubler and lots of GIF format pictures.
FastBack II did not compress it any further, of course.

But worse, FastBackII made me loose my data: after filling the first
tape, the Backup dialog told me to "change the cartridge when it stops"
and then to "insert volume <number 2>". I did insert a second tape and
FastBackII reportet to write another 20 MB to it.
No warnings, no error messages; only completion messages. 

But even after reading the manual - page by page - I did not find out
how to restore the data from the first tape. The second tape restores
fine.
