We have one machine with a very high change rate like this. We are
successfully using -incrbydate on weekdays, and a regular incremental
every weekend to catch up - exactly as suggested in the TSM manuals.

No, the Data transfer rate for 9940B uncompressed is 30 MB/s or ~105 GB/hr. The Data
transfer rate compressed is 70 MB/s or ~ 246 GB/hr.

Hello TSMer,
please give me your estimation, what you think about some facts we are
confonted in a tsm project:
approximately 200 tsm clients (windows, unix) with a total of 7 tb of data.
800 gb per day to backup, backup window 4 hours
many db applications, so there are a lot of more tsm nodes
