What is Seafile's Best Backup Solution?

Hi, I’m a young boy and it’s been a while since I’ve approached to seafile, but I know the linux environment well.

I would like to know which backup solutions I can use.
Since today more and more virtual servers are being used through xenserver, I have decided to install Seafile under Linux Server.
I’ve created a script under linux he exports my virtual machine to a NAS, but I would like to know other solutions, maybe better.
Thank You…
