Personal data is on a micro SD card. After doing something worth
saving it's backed to the host drive by me running this bash script .
Backup() { \
if [ "$#" -gt 1 ]; then
echo "Too many arguments.";
else
echo "0 or 1 arguments are OK.";
if [ "$#" -eq 0 ]; then
echo "0 arguments is OK.";
destination=~/MY0.Bak;
echo "destination is $destination.";
else
echo "1 argument is OK.";
destination=~/MY1.Bak;
echo "destination is $destination.";
fi;
echo "Executing rsync.";
rsync \
-auv /home/peter/MY/* $destination ;
/bin/ls -ld ~/MY/MailMessages;
printf "du -s $destination gives ";
du -s $destination;
fi;
}
"ls ... MailMessages" just reminds me to clean the mailbox.
The SD is used in multiple machines at two sites. So my data is
fairly well protected.
If the SD fails, an inverse script restores data from a host drive, to
a new SD.
If a meteorite goes through a machine, I get the holes in the case
welded up and replace destroyed internals. If the drive is replaced,
I reinstall and configure the system. A nuisance but not a catastrophe.
If an asteroid or meteorite shower or volcano destroys the SD card and
all machines where it's backed, and I survive, data probably won't be
a high priority but I can look for an old backup DVD.
Thx, ... P.
