So . . . what IS the correct way to make "backups of backups"?
Sorry to take so long to respond. I am traveling and have only short
periods that I can spend on non-pressing matters.
To answer your question: the method that gets you the result you want.
I have used 2 switches in rsync to create a date/time copy of files
that are updated:
--backup-dir=/mnt/data/rsynccBackupp/$YEAR/$MON/$TODAY/$HOUR/ source/
target
creates an archive directory of older versions of files. I have noticed
at times that it creates copies of files that I haven't fouched. Needs
looking at, but it will something I'm doing.
The variables are set in the script:
YEAR=`date +%Y`
MON=`date +%b`
TODAY=`date +%d`
NOW=`date +%Y%b%d%H`
HOUR=`date +%H`
rsync -avbH --suffix="."$(date +"%Y%m%d%H%M") source/ target/
replaces the standard ~ at the end of the file being updated with
current time, in a numerical string. Keeps all versions of the files
together. Which suits you better.
As for how to 'backup your backup?' I copy everything from source
documents to my backup drives, and set cron to run the script for each
drive at a different time of day/hour - yes I backup current docs
hourly. I'm lucky - I don't notice rsync affecting my performance.
Timeshift is a great tool. I know you are correct to copy the system to
a different drive. I figure that if I get to a point where I can't
access the time shift files on /timeshift I'm in deep trouble. I just
re-install. / has only system files on it. /home/keith is sym-linked
from another partition.
In any case, copying /timeshift from your system OR your first backup
drive should be trivial for rsync.
Out of time, but I think that's enough to think about for now
