We have been using buta with ADSM to back up our AFS volumes for about 3
months now. After some initial capacity problems with the ADSM server (not
enough tape drives), it's working quite well. We back up around 50K volumes.
Full backups with four parallel streams takes about 24 hours; incrementals
take 2 - 4 hours. We're adding more tape drives and tape changers so we can
parallelize things further to try to reduce the full backup time to 16 hours
or less.
