How do I back up the contents of ixVolume (docker)?

I deployed immich, but I didn’t specify a host path when I deployed it at the beginning and chose “ixVolume (Dataset created automatically by the system)”.

Now I’m trying to use Cloud Sync Tasks to backup my data. But Cloud Sync Tasks does not show /mnt/.ix-apps.

What should I do???

Dont know why I cannot post image…
