I am studying RTOS and its backup policy.

Is there any RTOS which has backup policy like save data from SRAM to non-volatile memory before power failure?

It does not have to be an RTOS. any OS is ok :)

Does anybody have an documentation about it?

Best, Mirae

This is not really the responsibility of the RTOS but something which needs to be designed in to the system if required, whether or not using a RTOS. Issues can occur if a power failure occurs during writing to the non-volatile memory. There are numerous methods of managing this, such as having the non-volatile memory mirrored and checked with a CRC, so that if there is a power failure only one copy is corrupted.
