Include extension console logs No log gets output in the chrome debugger view, sadly

@Bassadin, I'm also experiencing an Internal server error when trying to use this extension, although i'm using Mac so I don't know if we're experiencing the same issue.

I wanted to share a command I found to show the logs for this extension - I thought perhaps this might help you get more details about your issue that you can add to your issue report here.

to show the extension logs, run docker logs docker_volumes-backup-extension-desktop-extension-service in your shell.

I got this, if it helps:

Your error seems to be related with incorrect Windows export path handling on docker. "Error response from daemon: \\\\Orzhova\\home\\Non-Drive Offline Backups%!(EXTRA string=is not a valid Windows path)"

I am working on Docker Desktop for Linux. In my case the error was caused by selecting an external path which hasn't been listed in the Settings>Resources>File Sharing. You must add your destination path there, or at leas a parent directory of the destination path.

I get the same error. I checked the logs and I see this entry. Is it supposed to say /vackup or is that a typo? I would guess that it's looking for /backup.

Having the same issue and there's no work around that I can think of. Running windows docker desktop you have to select a windows file system folder. You can try selecting a linux drive but you still get same error.

I can't see how export to file can work on Windows with WSL2

I can't see how export to file can work on Windows with WSL2

The only workaround is to use the Volumes workspace/area in Docker Desktop:

Volumes > [Select a Volume] > Exports tab > Quick Export

Quick Export is the same UI as the extension and it works. Seems like a simple typo in the Extension is trying to "vackup", not "backup" the volumes.

@simon-mottram-cucumber hopefully this helps for now
