A long time ago Keith introduced me to Dirvish. I spent days trying to
figure it out, and finally gave up. It is overkill for my needs. More
to the point, whenever possible I decline to use tools that I can't
understand, and I'm not smart enough to figure out Dirvish.
I'm sure that a simple cron job with a bash script running rsync will
do the job. And I can understand it. Just now I used:
rsync -avx --delete /home/jjj/ /media/jjj/Data/Home/
It took five or ten minutes to transfer 330G of data. It ended with an
error message 'some files/attrs were not transferred.,' and 'see
previous errors.' There were many pages to look through to find the
errors, but a simple file manager 'properties' look disclosed
that /home has 706,536 files and the backup has 703,496 files, with a
total size difference of approximately 1MB. The difference is probably
not significant, but I should look at the list of files that were not
copied just so I know that I don't care about them.
Making a command to copy / might be more complicated, and I suppose I
need to sudo it. I'd like to be able to copy the / backup to a new
drive and make it bootable, if possible.
