I'm upgrading my mac to snow leopard but I don't really have a external hard drive to back up my data or the software to do the backup. Is it safe to do an upgrade without backing up? Any help?
what happens if the system "burps" crashes or otherwise fails, where would your data be?
You always should have a backup, regardless of what you'll be doing. With Leopard, apple made it incredibly easy to have a backup. Plus tools like CCC make creating a cloned disk so easy that it would be foolish to do an upgrade without a backup
