Synology + Docker + Btrfs



Did anybody successfully enabled btrfs support in UrBackup running using official docker images on Synology NAS?

Even in privileged mode creating btrfs snapshots return Inappropriate ioctl for device error. Subvolumes are created correctly.

This is not UrBackup bug. This is problem with environment itself. I’m creating this post here with the hope that someone found some workaround.
