We start weekly backups every Friday night. They run through Sunday. There is a scheduled network outage on Saturday morning between 5am and noon. This will disconnect clients from the backup servers and the media servers from the master servers. Can anyone recommend the best way to pause these jobs? Here are the choices I'm considering:
1. Stop Netbackup daemons on all master and media servers Friday night and restart them after the network outage is done. I believe this will not allow all backups enough time to finish by Sunday night when our next backup window starts
2. Don't do anything. I'm not sure what will happed to jobs that are running including "User" database backups which get sent to the master server and run on a media server when the communication between those servers is gone. Also DSSU archival to tapes may experience problems when communication is cut between the master server who is sending the list of backup images to the media server to archive to tape.
3. Login immediately prior to the network outage and kill all backup jobs, stop Netbackup deamons and restart deamons after the network is back up. This has never ended cleanly. There's always jobs that don't stop. I almost always need to do some kill -9's to get the job processes to die and the rest of the daemons to stop. Also, partial images will be left on DSSU's which won't get removed. When jobs get restarted, they'll eventually run out of disk space because Netbackup left those partial images. Does anyone know of an easy way of cleaning out partial images on DSSU's?
Any recommendations are helpful. Thanks!
