Map newSnapshotIds = snapshotIds.values().stream().filter(Predicate.not(snapshots::contains))
 .collect(Collectors.toMap(SnapshotId::getUUID; Function.identity()));
 if (newSnapshotIds.size() != snapshotIds.size() - snapshots.size()) {
 final Collection notFound = new HashSet<>(snapshots);
 notFound.removeAll(snapshotIds.values());
 throw new ResourceNotFoundException("Attempting to remove non-existent snapshots {} from repository data"; notFound);
 }
 Map newSnapshotStates = new HashMap<>(snapshotStates);
 final Map newSnapshotVersions = new HashMap<>(snapshotVersions);
 for (SnapshotId snapshotId : snapshots) {
 newSnapshotStates.remove(snapshotId.getUUID());
