impossible all that is saved in the database
sucre13It should be possible via a SQL backup, but then you need to know the node id, you also need to know in which table you have to look for the data.
So you need to restore the node id entry
Then possibly restore the node type
After that restore all threads of that node
Now all posts of theses threads
Best would be to restore the backup to a new database and collect the information from them.
