It can't be "just" as susceptible as what happened here.
If you even do the straightforward "don't freeze time anywhere, just rolling copy all the files onto a hard medium", you may end up with logically inconsistent data, in that files from later in the backup may actually not have existed alongside ones from earlier ones, but if you write down the timestamps periodically, you end up with a way better end state than "I lost all the files".
At worst, you end up with "I may have lost the last 3 minutes worth of files from the last 3 minutes of the last backup I did".
