Well, I have a really large repository that I cannot have locally, and I'd still like to have the database locally (that is not that large), and be able to get Alfresco up to run. So basically, semi-testing purposes.
I hoped I could get this working by copying only that minimal content store, but I'm having troubles knowing what exactly I need to copy (tried to blindly copy first year/month from alf_data).
Thanks for the answer, though.
