[Question #212772]: incremental adding unchanged files

 

New question #212772 on Duplicity:
https://answers.launchpad.net/duplicity/+question/212772

I ran a full backup to an external USB disk, which completed with no errors, using the following command:
duplicity --verbosity info --name opus-shared --volsize 100 --asynchronous-upload /filestore01/Shared file:///mnt/external/backup-Shared
Backup stats are listed below.

As a quick check I ran list-current-files and counted the output lines. I only counted a little more than 75k even though the backup stats said it had backup up 211859 files.

I then ran a verify which reported no problem and that I had 211859 in the archive.

When I then run an incremental backup, using the same command as above, it starts adding files that are already in the backup but are unchanged since the full.
