Recently have come across a case where backup needs to be taken of a linux server hosting erp db on it with OS as Cent OS 6.9.
As a compliance, it needs to be kept for next 3 years.
I am not able to find documentation where Cent OS 6.9 is compatible and we can take backup of it.
have already checked below link but need more clarity.
