In my experience, you're better off avoiding NFS as much as possible. (Perhaps except when you're sharing a filesystem between VMs on the same machine.) Try something else, perhaps rsync, unless you know what you're doing. NFS over a VPN -- probably in for a rough ride. In NFS, you can set mounts as 'hard' or 'soft'. If hard, errors will get you stuck until the share is back. You probably don't want that. If soft, you're slightly better off, but remember that the retry settings are all per-mount, and perhaps one size doesn't fit all. As far as I know, when NFS goes awry, you get the same or similar behavior to a hypothetical HDD/SDD that just explicably decided to no longer do anything for a while. Your processes will be in a D state and won't be killable for a potentially long time.
