Use borg or other encrypted backup tool (Restic is also recommended by others in this thread). rsync.net is my offsite backup. Doesn't matter what anyone demands of them, all they ever see is an encrypted blob.
Anyway, my "home burned down rescue bundle" consists of a flash drive with a keepass export of my password vault and encrypted borg repo key / rsync.net ssh keys at the office.
Slightly less accessible in this pandemic world, but no safety deposit boxes needed.
I can't say whether this is a good choice for any particular use-case but I appreciate that it is an option ...
For those that are curious, yes, you can later export the key from your repo so that you have a copy elsewhere ...
>Backup archives are mountable as userspace filesystems for easy interactive backup examination and restores (e.g. by using a regular file manager).
looks like a really nice feature of borg. Thanks.
