How to implement the failure function in software with multi-server architecture?

Question

Database

Our software works in a multi-server architecture. this solution allows you to increase productivity, etc. Example:
Parent company: server in Moscow
Branch No. 1: server in Nizhnekamsk
Branch No. 2: server in Krasnodar
Example from the situation:
Branch 1.12. employs 100 people.
In order for the information to be uploaded to the database of branch No. 2 and the parent company, branch No. 1 needs to send an electronic document with information on the number of employees. If you do not send such a document, then the database in the parent company will not be updated.
Now the client (parent company) asks to implement the ability to roll back data on the number of employees in the selected branch to a certain date.
Please tell me how to implement the rollback function in software with a multi-server architecture?
