Why each option
SnapMirror backup vault relationships are identified by the DP type in ONTAP 8.2 when vault policies are applied, and by the XDP type which was introduced as the dedicated extended data protection vault relationship type.
SV was a legacy SnapVault designation specific to 7-mode Data ONTAP and is not a valid SnapMirror relationship type identifier in clustered ONTAP.
DP (Data Protection) was the original SnapMirror relationship type used in clustered ONTAP 8.2 where vault backup policies could be applied to define backup retention schedules on a DP-type relationship.
BV is not a defined or recognized SnapMirror relationship type in any version of clustered Data ONTAP.
LS (Load-Sharing) identifies a SnapMirror relationship type used to distribute namespace read traffic for root volumes, not for backup vault purposes.
XDP (Extended Data Protection) is the dedicated SnapMirror vault type introduced in ONTAP 8.2 that explicitly supports backup vault relationships with flexible label-based retention policies and longer snapshot chains than standard DP mirrors.
