When too much process on appliance, randomly some of database backup fails at the middle of process

Hi Mark,

Thank you for your very fast reply.

At least 2 months later, nbu will be upgraded, so, i need a different solution.

Full backup is taken once a week, on saturday, and 3rd copy of this backup duplicates on tape. Tape library has 2 drivers, so, 3rd copy duplication finishes on wednesday. i face this problem only sunday, monday, and tuesday. If i killed all duplication jobs, i dont face these errors.

Duplication jobs are tried to delay by using LIFECYLCE_PARAMETERS and crontab. Also rebase state is off automatically by crontab on saturday and sunday.

i actually did 2nd link changes on LIFECYLCE_PARAMETERS on master server. According to my observation normally daily duplications finish until 8am, after these changes this jobs dont finish until 10am. Also i faced with 83,84 errors on duplication jobs.

First link has different changes on appliance, actually i am a little afraid, if i do this changes, can i face with bigger problems?

Thanks

You can safely do all of the changes from the first link as well but of you want to go carefull do the size and number DATA_BUFFERS, just:

echo 800 > /usr/openv/netbackup/db/config/DPS_PROXYDEFAULTRECVTMO

Set /usr/openv/pdde/pdcr/etc/contentrouter.cfg

WorkerThreads=128

and see if those help - you do need a full service re-start to get them to take effect

This contentrouter file is nearly empty, is it normal? Do i need to add this settings?

That looks very small - maybe just how vi displays it?

Does it look the same when using more?

we are going to upgrade it to 7.6, thank you Mark
