Restoring old messages from a raided server

I think restoring messages from a raided server (I'm talking about messages which were send before a server is raided) will be pretty useful. 

If it is possible discord could use similar to restoring DM messages strategy. 

User can request a package specifically made for the server. Discord will send the package to the e-mail. In the package every single text file can be for different text channel in the server.
