Controlling disk space for Accelerator track logs
At the start of an Accelerator-enabled backup, NetBackup can anticipate a disk-full situation due to track log processing. Accelerator track logs on a client can become a problem for clients with very little free space.
By default, NetBackup prevents an Accelerator backup if there is less than 5 GB or 5% of free space on the system.
NetBackup provides the two configuration settings to control the amount of free disk space on a host for an Accelerator backup to start:
ACCELERATOR_TRACKLOG_FREE_SPACE_MB
ACCELERATOR_TRACKLOG_FREE_SPACE_PERCENT
The default value for each setting is 5120 MB and 5%, respectively.
Note:
If either of the settings is not specified in the configuration, the default value for that setting is used.
If you set the ACCELERATOR_TRACKLOG_FREE_SPACE_MB value to X, the job will not fail if there is more than X MB of free space and there is more than 5% disk space (the default for ACCELERATOR_TRACKLOG_FREE_SPACE_PERCENT).
Similarly, if you set the ACCELERATOR_TRACKLOG_FREE_SPACE_PERCENT value to Y will not fail a job if there is more than Y% disk space free and there is more than 5120 MB of disk space free (the default for ACCELERATOR_TRACKLOG_FREE_SPACE_MB).
To use only ACCELERATOR_TRACKLOG_FREE_SPACE_PERCENT and not ACCELERATOR_TRACKLOG_FREE_SPACE_MB, specify the ACCELERATOR_TRACKLOG_FREE_SPACE_PERCENT value and set the ACCELERATOR_TRACKLOG_FREE_SPACE_MB value to 0.
To use only ACCELERATOR_TRACKLOG_FREE_SPACE_MB and not ACCELERATOR_TRACKLOG_FREE_SPACE_PERCENT, specify the ACCELERATOR_TRACKLOG_FREE_SPACE_MB value and set the ACCELERATOR_TRACKLOG_FREE_SPACE_PERCENT value to 0.
