I'm trying to do a backup, and it seems to be taking more tapes than I expect it should. Here are the details: NetBackup Data Center 3.4.1 Solaris 8 master and media servers and clients DLT tapes, 35

Hi Adam, This is interesting. I looked up the native capacities for all types of DLT. Since you say 35GB, I assume you have DLT7000. If not, that may be you problem DLT4000 - 20GB - DLTtape IV DLT700
Yes, we're using a DLT7000 drive with DLTtape IV. Density is correct. That's exactly what I don't grok, either, which is the problem. The backup is filling up these tapes, but I can't figure out what
Turn on client side logging and see exactly what files it is backing up. Yes, we're using a DLT7000 drive with DLTtape IV. Density is correct. That's exactly what I don't grok, either, which is the p

You can check to see if you're "starving" the tape drives in the bptm logs on your media server. If you see "waiting on full buffers", then the data is delivering to the media server too slowly and y
Not true unless you have a very old model. The first gen had half the buffer space (4MB I think) and would decrease compression (not tracks) when inbound data dropped below a certain amount. It only

Yeah I wrote a script to sum up all of the waits and delays for full and empty buffers in the daily bptm logs. Each delay is either 20 miliseconds on average for an empty buffer delay, and 30 milisec
