Yes I use multiplexing a lot

NBU 5.1 Master MP2 + 2 SAN Media Servers

4 drives in a robot - using SSO

1 Storage Unit set to multiplex 25 jobs per drive (Master)
2 SAN Storage Units set to use 2 drives, multiplex 8 per drive

Seems to work - get a lot of jobs done - around 300 per night if that helps.

Subject: [Veritas-bu] Multiplexing



We are struggling to get all of the backups run during the backup window and
one of the obvious solutions is to start using multiplexing as the tape
drives are not being driven at any where near their maximum throughput.
There has been a rather nasty multiplexing problem fixed in 6.0 MP3 but I
would be interested to do a straw poll of how many people are using
multiplexing and if possible any issues encountered.

I would appreciate it if you would respond (off list) as to whether you use
multiplexing or not (any version of NetBackup). I will summarise the results
and post back to the list.

Regards

Richard
