Symantec Advanced Threat Protection (ATP) allocates 1 GB of disk space for saved reports, and regularly monitors this space to ensure that it is not exceeded. This process ensures that the number of saved reports does not grow uncontrollably and consume too much space.
When 90% of this allocation is reached, ATP generates the following System Needs Attention message in the System Health Indicator in ATP Manager:
Device is encountering high disk space usage by reports
When 100% of this allocation is reached, ATP generates the following System Is Critical message:
Device encountered maximum disk space usage (1 GB) by reports
When the maximum allocation is reached, ATP frees up 10 percent of this space by purging saved reports, beginning with the oldest to newest. When ATP purges a report, the report and all its data are removed from your server. As such, you may want to download older reports before the purge occurs.
ATP does not purge the reports that are less than 30 days old. If the maximum allocation is reached by reports that are less than 30 days old, you may want to manually delete the reports that you no longer need. See Deleting reports.
