I have a client that I am contracting for that regularly (every few weeks) shuts down all Netbackup services on all Master & Media servers at their location and then reboots each of the servers. The environment is 7.1.0.3 Master and Media servers, three servers backup to a Data Domain and the other three backup to MSDP pools located on each of the three servers. This is what they consider "maintenence". The reboot of the media servers with the MSDP pools take a tremendous amount of time as the pools are very close to their 20TB capacity. This process takes at least 6 hours - bpdown, reboot and bpup. Spoold and spad are set to be started manually. This whole process takes up a tremendous amount of valuable time as we are VERY close to the technical limit of starting one job every second so every second a server is down leaves us trying to catchup with the workload that floods into the systesm every day.
My question is - Are we gaining any benefit whatsoever from doing this process every other week?
