We saw this error today on a 2019 server domain controller:

Log Name: DFS Replication
Source: DFSR
Date: 20/09/2020 21:00:08
Event ID: 5014
Task Category: None
Level: Warning
Keywords: Classic
User: N/A
Computer: DC0.domain.local
The DFS Replication service is stopping communication with partner -DC1 for replication group Domain System Volume due to an error. The service will retry the connection periodically.

Additional Information:
Error: 9036 (Paused for backup or restore)
Connection ID: F65BCC13-DC07-451F-92F8-A0E252F5D488
Replication Group ID: 329E9E69-8D98-4557-B2AA-4C3E4455A3C3

I am presuming that this is OK as 21:00 is when the domain controller is backed up...

This is often due to the System State backup of said server - the system can halt replication during this action.

You can disable DFSR replication for the time period of the backup using the DFS console. Under the replication section you can find a schedule if you open properties of the AD group and click edit schedule.
