Failed: The source folder E:\

Hi, I have a question. In the backup process, I have folder E what is a USB stick. If don’t have USB stick attached to PC get error

BlockquoteFailed: The source folder E:\ does not exist, aborting backup

Is this mind, all backups are aborted or accessible folders are backup, only, folder E is not?

You can use set the –allow-missing-source option to have Duplicati continue in these situations.
