Description of my issue:
I have three sites on two different hosts, and a couple of days ago the cron backups of just two of those sites (each on a different host) started to fail to upload the archive to Dropbox - see attached warnings from the backup log. The third site was unaffected.
After some tinkering and head-scratching, I realised that the common factor is the dropbox account. The two sites with this issue use the same Dropbox account, which a couple of days ago was affected by a Dropbox upgrade and now uses dropbox2.com with its new "improved" interface.
The third, unaffected site uses an account which is still on the old Dropbox interface at dropbox.com, though how long this will be the case I don't know.
For now I have switched all three to upload to the "working" dropbox account, but it can only be a matter of time before that gets the Dropbox upgrade treatment, at which point I expect the upload to break again.
Thanks,
Tim
