To increase logging verbosity, bp.conf and nblog.conf files can be updated on NetBackup Snapshot Manager for Data Center at /cloudpoint/openv/netbackup. See NetBackup Logging Reference Guide
Changes to the bp.conf and nblog.conf files come to effect when the next backup from snapshot or restore job runs.
The default configuration for datamover logs is as follows:
Log retention maximum period is 30 days. Logs older than 30 days are deleted.
The default configuration for high and low water marks for datamover logs is 70% and 30% of the size of "/cloudpoint" mount point. For example, if the usable size of the
/cloudpointfolder is 30 GB, then the high water mark is 21 GB (70%) and low water mark is 9GB (30%). In case, the logs directory (/cloudpoint/openv/dm/) size reaches to high water mark, older logs for which the datamover containers are cleaned up and no longer running are considered for deletion. The logs are deleted for such datamover containers until low water mark is reached or no logs are remaining for the datamover containers cleaned up or no longer running.
Modifying the default configuration:
You can modify the default configuration for log retention by adding such a section in the flexsnap.conf on the primary NetBackup Snapshot Manager for Data Center. Open the flexsnap.conf file from the path /cloudpoint/flexsnap.conf and add the following section:
[datamover] high_water_mark = 50 low_water_mark = 20 log_retention_in_days = 60
In case of NetBackup Snapshot Manager for Data Center extensions, the configuration from the primary server are used. Once the configuration is changed in primary NetBackup Snapshot Manager for Data Center, the configuration is updated on each NetBackup Snapshot Manager for Data Center extension within one hour. It is not possible to have separate custom configurations for primary NetBackup Snapshot Manager for Data Center or the NetBackup Snapshot Manager for Data Center extensions and configurations should only be changed in the primary NetBackup Snapshot Manager for Data Center. Though the configuration is same for primary NetBackup Snapshot Manager for Data Center and NetBackup Snapshot Manager for Data Center extensions, the high water mark and low water mark for log size are calculated based on the /cloudpoint directory mounted on each primary NetBackup Snapshot Manager for Data Center or NetBackup Snapshot Manager for Data Center extensions.
Each NetBackup Snapshot Manager for Data Center extension maintains the logs under its own /cloudpoint/logs location.
