Re: How to restore BIOS-based backup on a UEFI machine

Finally out of curiosity: You mention using CPIO archives. Do you have
any input files above 8 GiB for your backup processes? I always
thought that to be the limit of CPIO?
My backups do not contain large files within the cpio archives, so I
don't know whether that would be a problem. But some of the archives
are much larger than 8 GiB.
I've just realized that I may never actually have restored such large
backups, but I have created contents listings for them, and if cpio can
do that, surely it can also restore (but I'll try a real restore just to
be sure).
Since cpio as I use it works from and to standard input/output, I would
not expect it to notice the archive size in any way.
I back up with
cd / && find home -xdev -print0 | cpio -o0 -H crc | gzip | openssl
enc -md sha256 -salt -pass file:passwordfile -aes-128-cbc
>backup.cpio.gz.aes
Thanks to you and everybody else who answered my question.
