We have a web application with single site collection and one document library, mainly used for uploading supporting business documents (.pdf, .doc and .xml). Current content DB size is 160 GB with daily increase of 2 GB reaching closer to set 200 GB limitation set by Microsoft best practices. I read on blogs if the site is solely used for Records Center content DB size can go up to 1 TB.
Does 1 TB rule apply to our site collection? Anything we have to know or do to avoid any disaster?
