Incremental Backup error

I created a incremental backup with different folders.

When executing the inremental backup a new file is created for each folder. Everything works fine, if the folders a big enough.

I have some small folders in my Backup-List. Therefore if there are no changes the backup is finished within some seconds.

Then toucan tries to create a new 7z-File for the next folder. Because this happens only seconds later, it still is the same minute and the new filename would be the same.

This leads to an error (cannot create file because already exists).

To avoid this problem, I created a batchfile and start every folder as a seperate job and wait 70 seconds in between.

It would be a nice idea to use the same incermental-backup-file for all folders in a future version
