WOW! I'm really scared... I have a 300 MB backup course (Moodle 2.5.2+) and I only can upload 150 MB: It's not related to php.ini (max_upload_size = 512 M) but my hosting account. I don't know where, but I think I have read that it can be uploaded any size file by ftp. If so, are backups located in moodledata/filedir? Then, how could I "transform" my backup on that long numbers and letters string? I think the answer is in this thread, but I can't understand it.
If it is too hard, I prefer to build another course (the truth is that it is a course of a workmate and I can´t spend too much time on it. My backups weight less than 20MB because all the heavy files are linked to dropbox)
Thanks so much for your help!
