Duplication of Oracle backups to tape is sometimes slow

Level 4

Hi all,

We use NBU on Windows 2008 64bit, backup tot DataDomain and duplicate to LTO4 tapes.
NBU is configured to have minimum dup-job sizes etc.

It seems that Oracle backups duplicate very slow. Looking at the details of the dup-job it seems that the job is broken down in many small parts, possibly representing the different tablespaces etc. Between every part a new bptm process is started and 10 seconds delay occurs.

Backing up 200+ servers with 40+ tablespaces the delay is hours per day.

Can this behaviour be avoided?


Thanks in advance.
