Shared Linux folder on Windows

Hi All

Good day!

Our client is planning to backup a Linux Server( CentOS 7). So one of their options is to create a Linux Shared folder that is seen on their Windows Server.

Basically, its more on a File Shared folder. How can I backup the Linux shared folder? Is the backup policy should be on Linux or Windows? Do I need root credentials in order to backup the shared folder?

Also, as I've checked in the SCL of NBU 7.X CentOS 7 is compatible. If our client encounters a backup problem in ther CentOS is it supported by the Tech support if I create a case?

If there are any guides, im willing to read them.

Thanks in advance
