Daily tasks of Backup Admins
In this article I would like to share what Symantec consulting recommends that Netbackup Administrator perform the following tasks to ensure a properly funtioning Netbackup domain.
This information has been taken from from Symantec Netbackup Configuration Report document.
- Monitor all NetBackup daemons are running on the master and all media servers. This can be monitored from the Console > Activity Monitor >Daemons.
- Monitor all NetBackup processes are running on the master and all media servers. This can be done from the Console > Activity Monitor > Processes tab.
- Monitor all backup jobs and investigate any failed jobs. This can be done from the Console > Activity Monitor > Jobs tab.
- Monitor the health of all backup devices. This can be done from the Console > Media and Device Management > Device Monitor
- If the drives are in a down or unknown state, investigate the causes through system logs or Event Viewer logs. Downed drives can be upped from Console > Media and Device Management > Device Monitor > select one or multiple drives > Actions > select Up Drive.
- If the drives are in an unknown state, reset the drive to NetBackups known state from Console > Media and Device Management > Device Monitor > select one or more device > Actions > Reset Drive.
- Resolve any pending tape mount requests for restores or backups. When NetBackup cannot automatically service a tape mount request due to a particular media not being available, operator action is required to complete the request. This can be seen from Console > Device and Media Management > Device Monitor > Drives Tab. After the requested media is inserted into an available drive, from the Actions > select Assign Request.
- Monitor availability of Media in the scratch pool for the daily backup operations. This can be done from the Console > Media and Device Management > Media and selecting the Scratch Pool.
- Pre-labeling media will speed up mounting of tapes during backups. To pre-label tapes, from the Console > Media and Device Management > Media > select the volumes to be labeled on the right pane > Actions > select Label and check “Verify media label before operation”.
- Monitor for Frozen and inactive media. This can be done from Console > NetBackup Management > Reports > Tape Reports > Tape Summary. A frozen media is unavailable for backups and never expires. To unfreeze the media, from the Console > Media and Device Management > Media > select the media to be unfreezed and Actions > Unfreeze.
- Monitor the NetBackup Problems Reports or All Log Enteries reports for NetBackup Errors. This can be done from Console > NetBackup Management > Reports > Problems or All Log Entries. The Troubleshooter can be launched by selecting a particular line in the reports pane and right clicking to get additional menu items as shown below. Troubleshooter provides explanation and tips for resolutions of the problems.
- Monitor the disk space for NetBackup Catalogs and log files. If necessary add additional space before the file system gets full.
- Periodically run the check_coverage script from the /usr/openv/netbackup/bin/goodies directory to verify that there are no gaps in client file system backups.
Performance metrics of Symantec Netbackup Server
Symantec consulting recommends the following metrics be tracked on a regular basis to ensure an optimally performing NetBackup infrastructure.
CPU load: Recommend that it be less than 80% throughout the backup window.
Memory usage: Less than 90% usage all through the backup window.
Catalog Disk Space: Less than 90% full.
Daily Backup Volumes: Trends point to impending problems with the capacity of the infrastructure.
Backup Jobs outside the window: Points to schedule adjustments.
Backup Failures: Recommend less than 5%.
Backup Failure Code Trends: Points to other environmental problems in the enterprise.
Media in the scratch pool: Recommended to have at least twice the number of media required for a weekly full.
Restore Start Times: Points to tape drive resource contentions.
CPU load: Recommended to be less than 90%
Memory usage: Recommended to be less than 90%
HBA Saturation: Recommended to be greater than 85%
NIC Saturation: Recommended to be greater than 70%
Tape Drive Utilization: Recommended to be evenly used across all tape drives
