}
I use hardware compression to max the size of the tape. Uncompressed the tape
is 800GB compressed the theoretical max size is 1.6TB. I know that I will not
get the 1.6TB.
In the amanda.conf file I tell amanda that my tape is "length 1500 gbytes" and
that my tape drive uses LEOM.
Why does amanda stop at %52 when I still have 1.5TB of data in the holding
disk to write to the tape? It is hard to believe that the LTO4 compression is
so bad that I am not getting any compression at all.
Does anyone else have a similar setup if so do my parameters look OK.
Thanks
