Was looking up something for a backup operation and saw a command where someone was catting from ssh... I'd never thought of doing it before, but it does make sense:

Just log onto the server and see how I arranged the backups... duh! Server's disk has corrupted irrecoverably. Hope those backups worked (won't know until I can buy a new disk on Tuesday).
