Hi Scottthepotter,
Welcome to our forums.
If you have a dedicated NAS machine, you could configure your CentOS box to mount the remote filesystem, using nfs
for example (most NAS devices should support it). That way the remote storage appears in your local directory hierarchy, so all else you have to do is changing the target directory of rsync
to point to the remote filesystem.
To mount the remote exported filesystem, you can check our NFS configuration guilde, client configuration part. To configure the NAS to serve NFS, you can check the deviceās manual, but if unsure, if you provide us with details about it, such as version number, or options the management software running on it allows, Iām sure we can also help with that as well.
