I would like to backup my whole partition /dev/mmcblk0p2
as kind of an ad-hoc generated image file, because it’s file system is btrfs and backing up contained files themselves would not keep the internal structure (think of snapshots).
I tried to generate a symlink via ln -s /dev/mmcblk0p2 /my/backup/repository
, but duplicacy doesn’t want to follow that symlink, even though it is in the root of the backed up repository. Probably because it doesn’t lead to a directory.
Is there another way to do this? Note that the repository also contains other content, that lies next to the mentioned symlink.
