Comment:

 the procedure I actually followed is documented in "Restore the directory
 server" in:

 https://help.torproject.org/tsa/howto/backup/#index5h2

 Specifically, I have:

  1. shutdown postgres on both servers
  2. redid a BASE backup
  3. restored the base backup on the new server
  4. changed the bacula user password in postgres
  5. started the director (it was actually not stopped, but that didn't
 seem to matter)
  6. re-enabled and ran puppet on the director, holding a lock on the
 scheduler
  7. switched over a few nodes (perdulce at first, then pauli and alberti)
 and ran backup jobs on them
  8. switched over *all* nodes, and ran puppet everywhere
  9. ran puppet on the storage and new director servers
  10. released the lock on the scheduler

 I ran another backup job on crm-int-01 because it seems like an important
 server to backup, and might run more manual jobs on different servers like
 this, but not all, so we know the scheduler works.

 Once all backups return to normal, I guess it will be time to decom
 dictyotum!
