This exception can be thrown in case a storage commit is failed.
If a commit process of a storage failes on last transfer and the original
content may be corrupted the storage should throw this exception to notify
the user that a backup usage is required to restore the original content.
The storage itself must disconnect from the medium it is based on to allow
restoring. Although the storage will still contain all the data
internally, and can be used as a temporary storage usually used.
