Description of my issue:
I have a couple of sites where backups are succesfully taken but they are not being uploaded to Amazon S3 (although profile is configured to do so). In these sites, I have also noticed that trying to use the "Transfer archive to Amazon S3" feature from Manage Backups screen, gives an inmediate 500 error (I noticed that in my browser console).
Attached you may find the log for one of the sites (the one I am provided information) where you can see the postprocessing started. Nevertheless the file was not uploaded. This specific log is for a backup started automatically from Watchful.ly.
I would appreciate any help in fixing the "transfer archive to Amazon S3" feature so that I can move my backups there.
Best!!
