What is the best way to make a Full Backup of a CentOS 6.5 server?

Question

Backup

Hello dear visitors of the resource. The task is to fully backup Centos 6.5 with all the settings and the ability to deploy the system in case of a malfunction.

The main problem is the raid array, due to inexperience. I will be very grateful for any help on the issue, because attempts to find information on the Internet using search queries have practically led to nothing.

Answer 1

When you need to restore quickly - https://debian.pro/440

Answer 2

Depends on what data you have on the raids and the server.
If it's just files, then tar+gzip configs to another server.
And the files from the raid due to the severity, rsync with daily reaching out at some time.
If you have a database, then you need to backup differently.
Describe what you have for backup (free space, etc.), and what methods you can use (you can’t leave the company, etc.)

Answer 3

PostgreSQL and Active Directory databases on Samba 4. There is free space, no problem.
At the moment, the task is to clone the server to a tempo machine so as not to stop working while the server is undergoing maintenance (the reason is AD failures).
