Ditto, although increasingly I'm starting to use /opt as well.
One thing I like about my tar-based backup is that in principle I can
add additional "incremental" [*] tarballs to the base quite easily. So
I can, for example, take a current Raspbian, apt upgrade it to get
latest packages (and maybe a standard set of non-default packages I
use), then back it up as a snapshot. I can then take my "application"
code and include that in the backup so that it gets restored over the
top and ends up with a finished system, but in a way which is
more-or-less trivial to manage the OS updates separately from the
[*] It's not a true incremental backup as it would only replace or add
files, not delete them. But it's close enough for my purposes, and I'm
sure the extra deletion step could be brought in if needed.
