Hi @Anonymous,
Yes it is possible.
I'm just thinking why you would need to do such a thing. As SharePoint is document management storage system, there is on background automatically kept all history of changes on documents stored there. And also all files when they are deleted from SharePoint document library are kept in SharePoint site bin for some amount of days untill fully deleted.
But yes if you would like to mirror what is SharePoint doing in nature, you can create Flow that will take all items inside SharePoint document library each week for example and create copy of such file (content of file) in another library or Folder.
Actions are SharePoint get file content and Sharepoint create file.
If you want to list all items in library there is also action named SharePoint get files.
P.
