Yes, there’s a backup of @theymos in a cold storage wallet, kept safe in the same facility as Walt Disney… Kidding…
Apart from there being two admins as @iasenko pointed out, the site has daily backups, or at least had some time ago as a regular practice (see
Bitcoin Forum Bitcointalk.org Receives and Answers First Subpoena from DOJ).
The referenced article claims:
<…> Theymos clarified that all posts, whether deleted or edited, are “always saved forever.” PMs also end up in the daily database backup, which may or may not be kept forever, while IP addresses are only logged if you post <…>
Of course it is when you test the contingency plan that you discover if everything is under control, and I guess the plan would include the absence of @theymos and/or @cyrus.
