Firstly this plugin rocks when it is working properly.
We are using BackWPup to back a two instance of WordPress up to Dropbox. Some basic stats:
Size: 17.7 and 27MB
Dropbox: Authenticated successfully
Logfiles: look successful for both sites
I have been running the plugin every week for a while and have assumed that all was working ok as I have been sent the logs and also that on the WP dashboard it reported OK in green for the relevant date.
However, this morning I thought I would check the folder on Dropbox and was alarmed to see that no files have been uploaded since March and April 2012.
I can see that the backups are being captured as I can download them from the BackWPup Manage Backups area in WordPress, but they are not being uploaded to Dropbox despite this being reported in each of the log files:
2013/01/20 03:05.20: Backup zip archive create done

Thanks in advance for your help and I look forward to hearing from you.
