Ever reshape needs to backup its critical section. For this purposes
backup file or external metadata mechanisms can be used.
Add verification if backup file or metadata mechanisms can have chance
to restore data form backup.
For native metadata existence of passed (from command line) backup file
is checked. For external metadta manage_reshape() and recover_backup()
are tested for this purposes.
