No, this raises the issue of version control and data duplication. One of the main reasons data storage is centralised is not only to make sharing easier and ensure that the data being accessed won't have conflicting changes, but to centralise backups as well. This makes backing up much easier and quicker, but obviously you must have the correct backup infrastructure set up and running in production, which in the case of LMG, was still a work-in-progress.
Imagine if you ran a business with 100 employees, and all of them saved to their own computers as well as multiple servers! Not only would the workflow be tedious and frustrating, but it'd also end up being a mess after a little while.
