[nmglug] Recommendations for rsync backup subsequent to Debian release upgrade

Happy New Year nmglugers,
Yesterday I finally got around to doing a 'release upgrade' on the
laptop I most often use (hence the reluctance and tardiness; HP-Notebook
running Debian 10 Buster KDE to Debian 11 Bullseye KDE.) This performed
"in-place" versus my more traditional "nuke-n-pave" procedure (ref
In preparation, and per said ref recommendations among others, I also
performed a full-system rsync backup onto an external spinning USB drive
which had/has relatively modest extra space remaining.
I used this command:
sudo rsync -aAXv --delete --exclude=/dev/* --exclude=/proc/*
--exclude=/sys/* --exclude=/tmp/* --exclude=/run/* --exclude=/mnt/*
--exclude=/media/* --exclude="swapfile" --exclude="lost+found"
--exclude=".cache" --exclude="Downloads" --exclude=".VirtualBoxVMs"
I know I could bunch all those '--excludes' between braces, etc., but
I'm lazy, and despite wading through the man page now and then I can
never remember or fully comprehend all the ins and outs of rsync. So on
the rare occasions that I actually bother to do a full backup, I just
copy and paste the above in a text console with minimal modifications
(usually only the source and destination specifications). I got the
exact command string from some old notes I originally made mostly from
an Average Linux User article and watching some YouTube videos.
So in theory I now have what should be a sufficiently functional
full-system and home directory copy with which to restore the entire,
but now superceded, Debian 10 installation--if for some reason that
should have become, or should in the future become, desirable.
That now seems relatively unlikely and undesirable as, at least at
present, everything I've checked in the upgraded Debian 11 appears to be
present and working properly.
And now that I have the new upgrade, it seems reasonable--especially
since tomorrow is New Year's Eve and everything--that I should promptly
do another rsync system backup to protect my new investment of time and
effort and also the new data related to and stored in the now
substantially modified system.
So I was thinking that I would just change the name of the destination
directory in the external USB drive to reflect the fact that it would
now be a Debian 11 backup as opposed to a Debian 10 backup, and do the
same rsync command above, again.
The size of the net delta between the Debian 10 and 11 backups should be
relatively small, right?
But I'm also wondering about things like the flags --delete and
--exclude=".cache" and --exclude ".ecryptfs". And maybe I should review
I want to "strike while the iron is hot" before attrition and the
demands of the new year destroy my focus and resolve. But I also want
to err on the side of caution.
So my remaining questions are: 1) am I about to do anything stupid?;
and, 2) does anybody have any thoughts or suggestions about rsync and
backups that I should be aware of or might benefit from?
