For recursive mirroring common use would be
rsync -a --delete --progress sourceDir destinationDir/
Your example: rsync -a --delete /media/jjj/Movies /media/jjj/Synology/
Good way to see if you want to use --delete might be to count the number of
files to be updated and/or deleted with dry run '-n' and base on the number
decide what to do:
rsync -an --delete --progress sourceDir destinationDir/
This will print all files being deleted and updated.
Your example: rsync -an --delete --progress /media/jjj/Movies
/media/jjj/Synology/
In bash script you could do something like this:
#!/bin/bash
updateMax=100
deleteMax=50
filesToUpdate=$(rsync -an --delete /media/jjj/Movies /media/jjj/Synology/ |
grep -v 'sending incremental file list' | wc -l)
filesToDelete=$(rsync -an --delete /media/jjj/Movies /media/jjj/Synology/ |
grep -v 'sending incremental file list' | grep '^deleting ' | wc -l)
if (( $filesToUpdate < $updateMax )); then
if (( $filesToDelete < $deleteMax )); then
echo "INFO: Files being updated: $filesToUpdate"
rsync -a --delete --progress /media/jjj/Movies /media/jjj/Synology/
else
echo "WARNING: Too many files to delete $filesToDelete ... Updating only"
rsync -a --progress /media/jjj/Movies /media/jjj/Synology/
fi
else
echo "ERROR: Too many files $filesToUpdate changed. Skipping update ...."
fi
exit 1
It you run it manually, you will see the output. If you run it as cron you
could write it to a log or let cron will send you email with the output or ...
I hope it helps, Tomas
