This attribute has a value equal to the number of backup log files that will be retained for historical analysis. Any integer can be entered depending on the partition size and available disk space of the local system. The default value is 3.
Entering a value of 0 is interpreted to be the same as a value of 1, meaning that if you specify 0, a history log file will be created.
The value in this attribute is only used when the Logging Type attribute is set to FILE. If Logging Type is set to DB (Database), there are no history files.
