EPICenter Log Backups
Both the EPICenter Event Log and Alarm Log files are kept in tables in the EPICenter
database. These tables can contain approximately 50,000 entries.
The EPICenter server checks once every 24 hours to determine is either of these logs has
reached its maximum size. When one reaches its maximum, EPICenter moves the oldest
10% of the entries to a backup file, and clears those entries from the table.
Thebackupfiles arecreatedinthe directory
<install_dir>/user,where<install_dir>
is the root directory of the EPICenter install, by default epc3_1.
