Symptoms? Could be that the "problem" is different.

tar cfp  --exclude=$stuff $SomeDirs | ssh -> $BackupServer | xz -f

The process is semi-automated (PXE server).

cat /usr/local/bin/DateStamp
date +%H%M-%d%m%Y

rsync would likely be quicker. For full disk backups I remove the HDD
and put it into a box for disk -> disk copy (fastest).

apt-get install dokuwiki
navigate to http://localhost/wiki in your web browsers and start taking
notes instead of relying on your memory.

Slight correction (I failed to scroll right in my notes). 21 kernels and
header packages.

determined the kernel in use e.g.:-
uname -r

confirmed that the kernel functioned properly

listed all the kernels and kernel header that were installed, except
what was relevant to the kernel in use, and removed them:-
apt-get -s remove `dpkg --get-selections|grep
'linux-image\|linux-headers'|grep -v 3.16` | more

If the projected results look fine, rerun the command but replace "-s"
with "--purge -y", and also remove the "| more".

If it turns out that was the wrong thing to do... just as well you have
a working box with a package cache and an internet connection, and that
you recorded what you did (starting with the initial "dpkg
--get-selections | ssh $SomeWhereSafe")


Kind regards
