Ipad2 backup to Mavericks, I'm confused
I had previously backup up my iPad to my macair to iTunes on 18 June 2014. When I logged in to iTunes I could see it there. I had previously been advised back ups don't overwrite but create a new file. So, I did a new manual back of from the iPad to the macair.
When it was finished, the 18/6/14 back up no longer appeared on the list.
I went to where I thought back ups were stored, ~/Library/Appn Supp/Mobilesync/backups . There are three back ups there but they say there were created 28/2/14, 18/2/14 and 8/11/14? Where have the 18/6/14 and 3/5/15 gone to? Both have different info on them that I wanted to keep but needed space on my iPad.
Hopefully they are somewhere else?
MacBook Air, OS X Mavericks (10.9.5)
