Mac OS X Time Machine recovery lost Data I did a backup with Time Machine on a Netgear ReadyNAS to save complete System(OS X Mavericks). Because I have installed OS X 10.10 Yosemite. Now I recovered this backup. But I lost about 200 GB of 360GB.

Has anybody an idea to recover this lost data from SSD?
This answer you provided in the chat above is important:


  Music, Pictures and Movie of my user account haven't restored. No, I didn't find those folders on the time machine disk.


If those folders are not present on the Time Machine disk as you indicate above, then they weren't being backed up by Time Machine. You have lost this data and there is no way to get it back.
