Every company has its own database?

SOLVED

I've just started supporting a Sage FAS Network install, and am working out how to make cold backups. When I go to the backup utility, I find that we have 20-ish databases, each with only one company. Did my predecessor set things up weird, or is there a practical reason for setting things up this way?

Further, is there another way to make cold backups that won't involve me manually starting a new job for each of all these databases?
