PG does not have a concept of differential backup since it does not track block level changes. Pgbackrest has implemented a different backup using timestamp of last update in data files. Not sure whether it works in windows.

Hi Team,

Is it possible to take differential Backup in Windows Server ? If possible please explain clearly?

I tried with different scenarios but I'm unable to take Diff Backup of the postgresql database in Windows server.

Much appreciated for Response.

Thank you,
