When I tried to download the 8 part backup from the Wordpres Dashboard, Part 1 was the same file as part 8.
However, when I viewed the directories where the backups were, I saw all 8 files and could download from there.
I'm using Backup Scheduler 1.3.2 and WordPress 3.3.2 within a test environment.
I tried deleting the files from the Backups tab and reinitiating the backup process again. I had the same issue.
Is this a known issue?
