I have about 4000 patients, my entire AC folder is 1.8 G, the AC database alone is about 300K and the import items is only about 500K. And I thought we imported a lot, but that' nothing compared to Bert. My backup (compressed) file INCLUDING imports is about 1.6 G.
I and my Nurse Practitioner see about 5K patients a year. My database goes back to 2002.
I know there are a lot of folks with a lot larger databases. The big issue will be the import items.
