as I wrote earlier on our LTO4 tape changer for speeding up the building
of the directory tree on restoring I replaced the default configuration file

    /etc/my.cnf

by another predefined

    /usr/share/mysql/my-huge.cnf

I suppose this might accelerate the backup also.

For speeding up the backup I provided 1500GB diskspace for buffering -
running all backup jobs parallel that are writing to the same cassette 
set. This did help a lot.
