[Question] Difference between WebUI backup & pivccu-backup

[steilerDev]

Thanks for the great work @alexreinert !

I got a quick question (as I'm currently working on an effective backup strategy for my environment).

I'd like to initiate a backup from a remote host. Since the WebUI has a backup functionality, I could use this to create the file. However I see that the pivccu-backup script does some significant work in order to generate the backup file. Is there any significant difference between the two methods - is one preferred over the other?

The resulting backup file is the same, but with pivccu-backup you can automate the backup process e.g. by cron.

looking into the resulting files, I can actually see some differences :)

pivccu-backup bundles the installed addons completely (I got hap-homematic installed), the CCU native backup only has empty folders. Additionally pivccu-backup has an empty eQ-3-Backup folder.

The rest seems to be equivalent :)

Thanks for the quick feedback!

If anyone is interessted in my script for getting the file off the API:

CCU_HOST="http://ccu.net"                                     
TARGET="/home/ccu/"                                                    
                                                                                
if [ ! -d $TARGET ]; then                                                       
    mkdir -p $TARGET                                                            
fi                                                                              
                                                                                
# Acquire session id                                                            
SESSION_ID=$(curl -Ls -o /dev/null -w %{url_effective} "${CCU_HOST}/pages/index.htm?client=3" | grep -oE @.*@)
                                                                                
if [ -z $SESSION_ID ]; then                                                     
    echo "Unable to acquire session id!"                                        
    exit 1                                                                      
fi                                                                              
                                                                                
wget "${CCU_HOST}/config/cp_security.cgi?sid=${SESSION_ID}&action=create_backup" \
    -O ${TARGET}/ccu-backup-$(date -Iseconds).tar.gz

I assume, that where is now an issue in the native backup as we addons were included in the native backup, too.

[steilerDev]

hmm - is there a place to report this with eQ3?

[alexreinert]

They will deny any support request that is not using the original CCU3 image on original CCU3 hardware. And they deny any support request that includes 3rd party addons.

[steilerDev]

oh fun - are there first party add ons? it would be interesting to see if those are included in the backup on an 'official' CCU

[alexreinert]

Not that I know.
