@nixCraft As I tell all my clients "You don't need a backup system. You need a RESTORE system."
(Yes, I know it's grammatically incorrect. My Poetic License is up-to-date so it's fine.)
@faberfedor @nixCraft Same. I use "You don't want a backup, you want a restore".
Edit: Lost in language confusion :)

@nixCraft
- Do you have a backup?
- YES!
- When was the last time you did a restore to test it?
- ....
Happened many times with new customers
@nixCraft 17 hours, no, 15 hours, no, 2 hours, no, 4 hours.
And I didn't get the latest versions of all the files back. The outdated files were pretty random -- things like six out of a thousand source code files from a project. Anyone have a suggestion for backup software for Mac that's more reliable than Time Machine, or at least tells you when it's failing to back up a file?
