Hey guys, I have several external HDDs here. I ususally only use one for backups and only update the others once or twice a year as a backup from the backup. All HDDs are fully encrypted with veracrypt. I have like 3-4 different passwords, 4 different pims and 4 keyfiles. The problem that I have now - I want to update the back-backups and forgot the damn combination of the passwords, pims and keyfiles. I could just delete the back-backups and set them up new... but that's a lot of work, especially...
