That would be interesting to group your findings/issues on RPU in a dedicated topic, because I don't think the logic changed recently So it's an interesting investigation to make.
@Andrew good news : the lvm id/name collision is the root cause of a lot of issues of the the file restore.
I think restoring the symbolic links will be hard to secure ( a symbolic link can point anywhere in the os and the disk are mounted in the xoa as root) and quite tricky to ensure we are not bombing ourself
I think we can add them to the zip/tar as (brokenà symbolic link, but we need to look into the impact on the client side file browser
