Wade wants to know if he can use network attached storage (NAS) with his Chromebook? Leo says he can mount the NAS as a drive, and he can access his NAS through the web. But to do a direct backup using Chrome may be nontrivial. Wade should check out the Chrome extension Network File Share.
The issue is doing automatic backups. He can file share, that much is certain. But Leo doesn't think an automatic backup exists because Google Drive handles it. Leo does say, however, that Synology has a Chrome Drive backup, so his NAS could go online and backup his Google Drive.
