I need a solution
You don't, if expired 'normally' it has gonr for good.
Perhaps you take a disk array across to a new server, the fragments are still on the disk in this example and so could be imported.
It is also possible to expire the images but only from the catalog, without actually deleting the backup data (fragments) on the disk. Again, these could be imported as they haven't actually been deleted.

@Martin :
- when they are actually deleted?
- if i have a restore.my data is on disk and retention has been over,Can i restore from disk then?How would i know that my data has not been overwritten or fragments have not been deleted?
