There was an earlier update about _recent support being added in SnapCenter 4.2 VMware Plug-in.
However, 4.2 has no VMware Plug-in - instead it is combined with NetApp Data Broker 1.0, which replaces all
the functionality and essentially has all other SnapCenter functionality required for management (NSM,
SMCore functionality, Web functionality) also embedded, in a Linux OVA and shows as the SnapCenter
Plug-in for VMware in vSphere as well.
And, I just checked in an LOD, and NDB 1.0 policies do not have a recent _methodology option.
Although there is a custom Snapshot field on the Resource Group, it will not use a singular name,
because _recent support will require renaming the Snapshot on the next Backup, so it would have
to be implemented as a choice between SnapVault Update or _recent prep for NDMP Backup,
possibly from SnapMirror (XDP, MirrorAllSnapshots) destination.
With NDB, that would have to become a new RFE.
P.S. the product code for NDB is XPLAT in BURT
