I've opened and altered an excel document. This is stored in "documents folder" I saved it (hit save), not with a new name. Now, however, i want to refur back to the original. I use time machine, but the documents folder is not backed up there. I've gone into "My iCloud" on the internet, but can only access current documents. Not older versions. where if anywhere are these older versions backed up? I assumed that the documents folder was backed up with time machine. I think/hope I've explained that clearly.
