The following deletion policies can be enabled:
Deletion based on time. Log files are deleted when they reach a specified age.
Deletion based on size. Log files are deleted when the total size of all the log files reaches a specified limit. The size of the current log file is taken into account, although this file is not deleted.
Deletion based on free disk space. When the free disk space reaches a specified minimum, the oldest backup log file is deleted. If the free disk space is still lower than the minimum, the next oldest backup log file is deleted, and so forth.
By default, log file deletion is based on free disk space, with a default value of 1 Megabyte. When all three deletion policies are activated simultaneously, they are processed in order of time, size, and free disk space.
