Hello everyone, 

I have a few folders that I have kept offline for some personal reasons. Now as the space in apple mail is filling up I thought that I can backup those folders so that I can recover them in future whenever I want to. I have tried the export function but it never exceeds 11% and the reason is unknown. And the problem with Time Machine backup is that it backs up everything. I need something specific that can backup only the required folders. Is there any such solution available?

Please let me know asap. Thanls
