Create more frequent previous iTunes libraries?
With all the talk of problems with Music Match, I verified that my computer has been keeping previous iTunes libraries. It does, but I was surprised by the dates of these backups: 7/1/15, 6/29/15, then 10/5/14, then 7/29/13, etc.
Since I frequently add content to iTunes, I would hope that a more frequent backup would occur. 15 months between some backups?.
Is there a way to create more frequent backups? Also, do these previous iTunes libraries include the playlists?
Thanks for your help!
