After some issues I had to create a new backup. Running the new backup of approx 340 GB, when there are 1,46 GB left (10321 files), the process stops (keeps inactive) with this information in the summary:
Last successful backup: Never - [Run now]
Next scheduled run: Tomorrow at 1:00 PM
Current action: Backup_ProcessingFiles
Progress: 0.00%
Current file: C:\Users\ricar\AppData\Local\Duplicati\EENDCPUXHZ.sqlite-journal
I will appreciate your help
Many thanks!
