Thanks for responding
The webdav reference does indeed point to a nextcloud installation on safeskies1.ddns.net which is a machine on my local network. The linux path is /media/nc-data/xxx.yyy/files. I’m also running samba so the ‘W’ drive shown in my windows command box points to the exact same location as does the webdav command. Sorry for that bit of confusion.
The dindex hack was actually from Doc Watson here: https://forum.duplicati.com/t/very-slow-database-recreation/10827/8 I wasn’t paying attention initially who was responding – sorry.
In regards to the 170 bytes, a working repair for the same account also shows 170 bytes (don’t know where this number is derived from), but then goes into “rebuild database started, downloading 17 filelists” whereas the failure goes straight to “Destination and database are synchronized, not making any changes”
Thanks
