Hello, I have a macbook air 2012 , when i use time machine for backup using an external backup, its backs up normally. When plugging it in and pressing Control R to into recovery and select Backup from time machine option under utilities, My drive shows up then further it says NO MAC OSX BACKUPS COULD BE FOUND. When using migration assistant , drive never appears. BUT, in finder while drive plugged in i see my backup.backup folder which means nothing is corrupted, but deeper inside that file i discover under Macintosh User then me most of my info is there but it missing APPLICATIONS folder , which is obviously needed in order to complete a full backup from time machine, that is why Time machine and Migration assistant do not want to recognize it. As of now my mac is fine , but i want to know what causing it to automatically not include some important folders while doing a time machine backup, i know i can always do the manual way (drag and drop from backup.backup) but time machine should work like it has before. I have called apple senior and they sent this up to engineering and there having trouble finding the problem . I have already reinstalled OSX but did not wipe my ssd because i do not want to take the risk of using Drag and Drop manual way. Also i made sure nothing is excluded from time machine in setting. This issue is coming from this macbook air as it is something software. thanks a lot.. sorry if it is confusing.
