Sharepoint to local server migration

[Buttknucks]

Good afternoon! I am currently needing to clear up Sharepoint space, but luckily have server hardware running for a project that ended up being abandoned. I am looking for some information on the best practices for getting the server set up to host a lot of this data as an archive to get it moved off the Sharepoint site and avoid having to spend more for more cloud storage. 

I'm also sick of getting an email every day that I'm out of space. 

 

So, essentially, I was hoping to get some guidance on the local server setup, and any information/tips for pulling the data down from Sharepoint (the current plan for pulling the data is going to be download a chuck, verify data integrity on the server, then remove from Sharepoint. But that's going to be a long process for multiple TBs of data, so if there's a better way please let me know).

My plan is also to get a license for the Sharepoint local front end for the archive server, but will probably wait to see how much the old data is even used before I spend money on that.

 

Apologies if this is posted to the wrong place.
