I've tested the new code and it works like a charm. I guess those
production servers are safe.

To restore a level 2 dump it needs to be merged as follows;

Get last successful level 0 dump (full)
Get last successful level 1 dump (incremental)
Get last successful level 2 dump

 merge /tmp/full1 lvl0 lvl1
 merge /tmp/full2 /tmp/full1 lvl2

Maybe someday merge will be changed to do it all with one command,
 merge /tmp/restored lvl0 lvl1 lvl2

But that has, alas, not been implemented yet.
