Full server backup?

Question

linux

There is a server on CentOS. I'm not very good at servers.
You need to make a full backup of the system with all configs, files.
What do you advise?

Answer 1

I used vmware converter for such purposes.
The result is a virtual machine - a complete copy of the server with centos.
Which then you can run even at home on your home computer.

Answer 2

man tar

Answer 3

If this is a virtual machine, make a copy of the virtual disk. Dumb but reliable. If bare-metal - then man dump :)

Answer 4

dd if=$input_data of=$output_data [options]

Answer 5

Capture a full disk image.

Answer 6

Request an image from the host.

Answer 7

If there is lvm, then you can make a snapshot, and then tar | dd | fsarchiver. At the same time, you can do something on the server in parallel and everything will be backed up normally.
