I've migrated some partitions to amanda once per week, starting
some weeks ago. Now that all stuff goes to amanda i wanted to see what
happens when i schedule a full over all partitions in one run.

Yes, the 2nd tape is used, and hardware compression is switched on.
i know it's a bad thing while amanda is guessing estimates, maybe
this is where i think wrong ?
amtapetype gives me this tapetype definition:
define tapetype LTO-Ultrium1 {
comment "LTO Ultrium1"
length 100864 mbytes
filemark 0 kbytes
speed 14300 kps
}
quoting amanda (at the run the "dumps too big" happen):

...so amanda thinks it has only ~200GB space on it's 2 tapes, even
if the 2nd tape has plenty of space left, right ?
i don't know if the next lines will tell me also not to use hardware
compression:

Thanks for your hints.
I guess i must play around with my settings some more weeks before
i completely understand what happens.
