zfs-bookmark — create bookmark of ZFS snapshot
zfs bookmark snapshot|bookmark newbookmark
Creates a new bookmark of the given snapshot or bookmark. Bookmarks mark the point in time when the snapshot was created, and can be used as the incremental source for a zfs send. When creating a bookmark from an existing redaction bookmark, the resulting bookmark is not a redaction bookmark. This feature must be enabled to be used. See zpool-features(7) for details on ZFS feature flags and the bookmarks feature.
