Well, yes and no. As long as the backup happened BEFORE the malware started encrypting your HD, the backup would contain the malware (Transmission 2.90 in this case), but its data would remain clean, NOT encrypted. The encryption happens only (AFAIK) when the malware is active and running, not just because the malware is on a disk. Hence, you could clean your Mac's HD, remove the malware from the backup, and restore the backup; and everything should be fine. Of course I would keep an eye on which Transmission version I would be running. As others have noted, backup disks can easily be compromised by malware when they are connected 24/7. As long as a a disk is on its own (not connected), no software can alter its content whatsoever. A good backup strategy would be having an always-connected backup disk (e.g. using Time Machine), and another disk for periodic backups (e.g. once a week), maybe stored offsite. This strategy would offer the safety of both an up-to-date backup, and a backup safe from whatever is happening to your computer right now (be it malware, a thief, fire, etc.). -- -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
