All right,
I had first to export the pool before i could import it again. After
import, the scrubbing goes on and it seems all right so far.

The One-Disk-Pool, the other one that failed, seems to have different
IDs since import compalins about multiple existences of a pool with the
very same name. How can this happen?

root at b211:/root # zpool import
   pool: BACKUP00
     id: 257822624560506537
  state: FAULTED
 status: The pool metadata is corrupted.
 action: The pool cannot be imported due to damaged devices or data.
        The pool may be active on another system, but can be imported
using
        the '-f' flag.
