Use the ArchiveTimeOfDay statement to specify a local time of day to perform an archive of all eligible UNIX files. Each configured rule that specifies a UNIX file as the destination and that specifies the -N parameter to indicate that it is eligible for archive processing is a candidate for automatic archival.
You can use this statement to perform archiving at a specific local time of day, or you can use the ArchiveThreshold statement to perform archiving when one or more file systems reaches a configured threshold. You can also specify both statements.
If the ArchiveTimeOfDay statement is specified multiple times, syslogd uses the last instance of the statement.
