I installed Duplicati for my mother and she gets this every time, deleting/repair does not work, looking at suggestions here and in GitHub on same topic some of it too much for us to try figure out… in the end I deleted her backup from destination and we start again. I wish the application could keep itself automatically in check and reconciled. Not everyone are technical and expect backups to work and repairs to actually repair.
As far as the back end storage - the only thing that ever touches it is Duplicati.
This is message we kept getting:
Remote file referenced as duplicati-bf4fb510dc367425884c441f24144b9ca.dblock.zip.aes, but not found in list, registering a missing remote file, Remote file referenced as duplicati-b6e51421b5b1740a59743b2a847bfcdb9.dblock.zip.aes, but not found in list, registering a missing remote file.
I hope it doesn’t happen to me, I have a hell of a lot more files than my mother!
