Description of problem:
Once backup is completed (rear mkbackup), customer would like to log message that "backup complete" with a timestamp and location of the backup so the result can be inserted into a database. 

Version-Release number of selected component (if applicable):
rear-1.17.2-1.el7.noarch

How reproducible:
Always

Steps to Reproduce:
Currently there is no provision to log message after successful backup completion.

Actual results:
Currently there is no provision to log message after successful backup completion.

Expected results:
Have some kind of provision to log message after successful backup completion only.

Additional info:
As a temporary hack, I modified /usr/sbin/rear bash script itself to log such message.

# Check for and run the requested workflow
if has_binary WORKFLOW_$WORKFLOW; then
        Log "Running $WORKFLOW workflow"
        WORKFLOW_$WORKFLOW "${ARGS[@]}"
        Log "Finished running $WORKFLOW workflow $BACKUP_URL"
        LogPrint "Finished running $WORKFLOW workflow $BACKUP_URL `date` " <<<<<< Added this line to print any messages and access variables 
else
        VERBOSE=1
        LogPrint "ERROR: The specified command '$WORKFLOW' does not exist !"
        EXIT_CODE=1
fi

I have not completely tested above but looks possible to get notification from here.
