Multiple BackWPup backups failing to Dropbox

Hello!

I have dozens of websites on a VPS that have all began to fail when uploading to Dropbox. There is plenty of space at Dropbox for the uploads. This only began recently but some of my wordpress sites have not been able to backup for weeks. Others will sometimes get one backup to finish, while failing 90% of the time.

Notice that the 3/17/20 backup did complete….?

Here’s the logs from one of the sessions, but the error messages are all identical. Specifically:

[24-Mar-2020 07:01:43] /home/website/public_html/wp-content/plugins/backwpup/inc/class-destination-dropbox-api.php: Dropbox API: incorrect_offset/.
[24-Mar-2020 07:01:43] ERROR: Aborted by user!

Aborted by user meaning the BackWPup process right, because I didn’t end the job manually.

I have tried some of the options from other threads like:

– Settings Maximum script execution time to 25 seconds
– Set Reduce server load to minimum
– Stagger backup jobs by 30 minutes

Hopefully we can get this fixed, I have many jobs configured and this was working well for a long time. Very strange.
