Hello
I want to schedule monthly backup on my router . I have not set ntp and my router is not connected to internet so i can not use internet for ntp. I set the time and date manually but i worry about changing after shutting down or reboot.
Does the router save the time on battery?
What should i do?

Use SNTP client.

Thanks
So i have to use sntp.
What should i do if it is not possible.
Is there any battery for time in mikrotik routers?

sntp client is all that is needed to time-sync the device.....but it still needs access to external ntp server.
Since there's no external connection, do you have internal devices acting as ntp server? A windows AD controller already does this job

Thanks

The MikroTik routers have no CMOS clock. So a battery would not bring anything.
You need to use SNTP with a server on your network, trivial to set one up.

Using usb gps and install gps package on your router then enable time sync from system>gps

When the ntp package is installed, there is no sntp client and there are ntp server and ntp client. In this situation how can i bring the sntp client option back. I do it with disabling ntp package. Is it ok?

Remove the NTP package, most likely you don't really need an NTP server in your home device.
If you do need it, look for new menu NTP client, not SNTP.

SNTP is "simple NTP" and is shown when you have no NTP server package.
NTP package enables NTP server and also installs new NTP client in other menu.

You can use "pool.ntp.org" as your NTP server, it will be more reliable.
