Does Percona backup for MongoDB v1.2.0 now support 4.2 Distributed Transactions?
Thanks in advance.

It does provide a cluster and transaction consistent backup. As far as I know it is the only open source tool that can take a consistent clusterwide transaction safe backup and is a viable alternative to solutions that ship with mongodb enterprise edition.
