Ok managed to get the restore thingy working! Yay.
To restore an area do following:
/snapshot use 2015-02M.zip
Select an area. (I suggest switching to "//sel extend" mode)
I'll go around myself this weekend but if you see something and have WorldEdit rights. Please fix it.
If the server is empty don't be afraid to do a really big area. You will disconnect but it will pull trough, just give it time. I restored the mining town that way. Took 5 minutes. Several tens of millions of blocks.
Entities will be restored. YAY
While I was at it I updated the server and plug ins ...
