first of all I want to thank the developers of DietPi for their amazing work. A couple of days ago I digged out my old RPi 1 and came across your site while searching for an adequate distro. Since then I have been playing around with it and setup my system. Mostly everything worked out fine straight away. Good job, guys!
So, now regarding the problem: Today I wanted to setup a backup of my system and started dietpi-sync. After setting the configurations to my needs, I wanted to check with a dry run and used that option from within dietpi-sync. After some strange error messages at the start of the run and rsync actually copying files, I checked your script and found a bug in the way you set up the rsync options:
#Rsync options local rync_options+="-aHP4 --info=name0 --info=progress2 --human-readable --delete-excluded --exclude-from=$FP_FILTER_INCLUDE_EXCLUDE --log-file=$FP_LOG " # - Compression? if (( $SYNC_COMPRESSION )); then rync_options+='z' fi # - Dry Run? if (( $SYNC_DRY_RUN )); then rync_options+='n' fi # - Delete mode? if (( $SYNC_DELETE_MODE )); then rync_options+=' --delete' fi
By simply adding ‘z’ and/or ‘n’ to the options string you mess everything up, because now there is no more leading ‘-’. Seems to me as those options were forgotten when you re-arranged the options string at some point. Changing the ‘n’ to ’ --dry-run’ fixed it for me.
Oh, I’m running on v6.19.7 | RPi B (armv6l)
I hope this is some useful information for you. Thanks again for the great work!
