After many trys of 41218 error,i use an software "wondershare" only for 100RMB.And recoved almost my file from the timemachine .sparsebundle file.
this is not an ad,it realy works!
this software can read backups from volumes from bad sparsebundle file which open with DiskImageMounter.app.
And time machine backup is not alwarys trusted,you should always have at least two backups like NAS,Dropbox etc.
