I agree with your idea, but your definition is overkill.
A backup is a copy of data on hardware separate from the live system.
A good backup is a backup in in a remote location.
A backup strategy is to maintain a good backup.
A good backup strategy is to have routine restore tests, to make sure that the backups serve their purpose.
A great backup strategy requires at least 2 good backups.
- tracker1 8y agoI understand... by 3 full copies, that can include the active in-use copy. I just don't consider something backed up short of having the data in a separate device and location.
- arghwhat 8y agoIt has to be on a separate device to be a backup indeed, just like a spare wheel isn't a spare if you're driving on it. The location thing is trickier, and while you can't have a any backup on the same device, you can have a bad backup on the same location. A bad backup is better than no backup by a long shot.
- tracker1 8y agoI'm fine with a backup on-site... I just feel that data isn't safely backed up unless it's off-site too. Not that everything needs to go that far. But it's usually useful to think in those terms imho.
