Hi, I have read through the FAQ and its got a lot of useful information from the backup section. I have encrypted /home and used cryptsetup --dump-master-key luksDump /dev/dm-2 and cryptsetup luksHeaderBackup --dump-master-key /dev/dm-2 --header-backup-file header to make a copy of the header incase I forget my passphrase. I bought a encrypted USB drive to put the header on. My first question is, if something like header corruption/ passphrase forgotten, would I be able to restore from my USB on to the LUKS partition and continue using /home as it was? What if I have unmounted it or rebooted the machine. Second, what else should I be doing in order to protect against accidents such as above? Lastly, a few people have access to this machine (through the same passphrase), some work colleagues, how can I protect against one disgruntled member leaving the company and changing the passphrase (then unmounting the volume for good measure) and not telling anyone?
