Why "DA logrotate" did not keep log filename as date format ?

logrotate use filename.date is better than filename.number
because all log no need to change the filename every day.

• *** Reduce the time for rsync backup (It greatly reduces the processing time)
• *** Reduce the time on snapshort backup
• *** Reduce snapshort storage size,
• Easy to find , read and view the log content
• Easy to remove older log

Example log filename.date

• /var/log/exim/mainlog
• /var/log/exim/mainlog.2023-06-17
• /var/log/exim/mainlog.2023-06-16
• /var/log/exim/mainlog.2023-06-15
• /var/log/directadmin/access.log
• /var/log/directadmin/access.log.2023-06-17
• /var/log/directadmin/access.log2023-06-16
• /var/log/directadmin/access.log.2023-06-15

/var/log/directadmin/access.log { daily rotate 21 missingok nocreate dateext dateformat .%Y-%m-%d
}

• dateext: This directive tells logrotate to append the date to the rotated log file name.
• dateformat .%Y-%m-%d: This directive specifies the format of the appended date. In this example, the date will be in the format of YYYY-MM-DD and preceded by a dot (.).
