No, because you’re reading the local file system using the local processor, which could corrupt reads or writes. Even DMA reads won’t solve it - malware could encrypt/decrypt transparently for a period undetected, then toss away the decryption key once it’s likely that backups are no longer viably usable..
- sodality2 6y agoI mean, if the malware is in the system before backups are even set up, sure it could be broken..
- hsbauauvhabzb 6y agoNot even before, it just has to exist long enough to trash backups for a while - reverting from a month old backup would be substantially damaging.
