They obviously had IT in some capacity; whoever they had set it up did them dirty if they didn't emphasize the importance of backups.
I know; I've been "that guy" who helped out a small company get on their IT feet, as it were. I always stressed the importance of backup routines, of how to take care of their data. I gave them scenarios where, if I get called for X, I won't be able to help them if they weren't on top of their backup routine. I always asked them what that'd mean to them and their business. I made a point of driving this home.
Of course I've received those calls, and I've asked the question, "What do the backups look like?". If they're my customers their backups are usually up to date and ready to go. An evening's worth of work, maybe a weekend, and they're back in business.
If they aren't, then my price just went up. WAAAY up.
