Enough?

I hope I now have a "fail-safe" backup plan:
1. Use CrashPlan, an online service for automatic backups.
2. Back up to external hard drive using Time Machine, automatically, every hour.
3. Copy photos and publications directly onto another external hard drive for safe keeping, remember to do once a week.
4. Retain external hard drive with contents of SHU laptop; no changes to be made to this.
5. Use small flashdrive for back-ups of work-in-progress, and keep handy at all times.
6. When writing with a colleague, email documents at the end of each significant work session.

What have I forgotten?

To clean the rest of my desk!
