Problem conclusion

• Before IBM Spectrum Protect Plus 10.1.16.1 and 10.1.17, a single
  vSnap preference was used to determine whether to an unforced
  export the ZFS pool when cleaning up both an offload and a
  restore. In IBM Spectrum Protect Plus 10.1.16.1 and 10.1.17, a
  new preference has been introduced for the restore (with a
  default value of enabled), enabling restore cleanups to perform
  an unforced export by default.
