Dear folks,
I have a PC with Windows 10 professional on it. This year I’ve installed Docker Desktop. On that I’ve installed Nextcloud AIO.
Over the months I’ve made a couple of backups with Borg Backup. That all works fine.
Now I want to have Borg Backup make a ‘fresh’ backup. A backup that doesn’t ‘build on’ previous backups. I thought I could force this by renaming the folder ‘backup’ to ‘backup-old’. That way Borg can’t find the old backups, and might automatically build a ‘fresh’ backup. However, Borg doesn’t like this. If I click ‘make backup’, it always fails. If I undo the renaming of the old backup-folder, everything works again, but this is not what I want.
How do I achieve what I want?
Hi, why do you want to create a “fresh” backup?

I started Nextcloud by putting large movie-files in it, to test the playback capabilities in the android-app, the browser, etc. Therefore the backup-folder is quite huge. Now I just use Nextcloud for Calendar, Notes, some current images and some other files. Reason #1 is to reduce the folder-size.
Another reason is that I use Borg Backup to migrate Nextcloud to a different PC. This just needs the current state of Nextcloud, without being unnecessarily chunky because of old - already deleted - files.
Also it’s to enhance my overall feeling of control over the Docker-Nextcloud thing 
Update
I saw another post from szaimen suggesting the following commands
sudo docker rm nextcloud-aio-borgbackup
sudo docker volume rm nextcloud_aio_backup_cache
However, I’m don’t know if these commands are also applicable to my specific situation. Also the first command looks like it’s deleting Borg Backup alltogether?
Yes! This worked great. Thank you!
