NAS Storage Issues

I’ve setup a NAS storage through fstab and everything seems fine. I’ve given the storage the folder of “/backups”.

The only catch is that I am having a number of problems:

  1. How can I see how much room I have left allocated for me on the NAS storage? Can I just go to the “backups” folder in ssh and give a command?

  2. It looks like the automated backup through cpanel/whm went to my primary hard drive last night, though it has been going to the NAS /backups folder just fine before. Why would this happen?

I just need a better idea of how to ensure my NAS storage is working.

Cheers
Ryan
