Hi @hlv008
Our plugin takes system time and timezone, so, same path can be used by multiple websites on one server without conflicts.
Otherwise it would be possible to modify timezone and our automated backups could cause issues.
I understand that changing timezone in your case may not happen, but we have to be most flexible as this plugin is used on huge amount of sites and various environment.
You can always check current server time in scheduled backup section when you hover on info icon, it updates automatically.
Hope it helps, let me know if I can help you any further ??
Thank you!
