I'm thinking about putting my backup encrypted files in a LUKS filesystem within a file instead of on a dedicated partition (for a few reasons).
I have two questions about that: * if I don't have that LUKS filesystem "mounted" and open and I write to it, I assume (or hope) that nothing will get written and I will get a warning or error message of some sort? * doesn't exactly apply to this situation, but, on the other hand, if my "source" / original / non-backup LUKS system is in a file instead of on a dedicated partition, and I use commands (like rsync or such) to copy the unencrypted files not on the LUKS system, but I use options like the ones to stay on the current filesystem (--one-file-system), I assume (or hope) that the stuff in the encrypted partition will not get copied?
