Comment 24 for bug 882699

Ok. To enlarge on my experience, the sequence of events is as follows;

I set up Deja Dup to back up to a named folder on U1.

My machine scans, prepares and uploads files.

A successful backup is reported, there are uploaded files on U1, including various control files. All appears good.

Future backups may well run correctly.

However, if an attempt to backup results in the code 500 error, that is the end of backing up to the named folder. Future attempts will not work.

Thus, once code 500 has been encountered it is a fatal error for that backup setup.

The only cure appears to be to start again with a new destination folder.

So the error is reproducible once it has started to occur.
