Timeseries are still not supported in sharded cluster:

• docs: https://docs.percona.com/percona-backup-mongodb/features/logical.html?h=time+series#:~:text=Warning-,Sharded%20time%20series%20collections%20are%20not%20supported.,-The%20following%20diagram

• ticket: https://perconadev.atlassian.net/browse/PBM-1295

I’m suggesting to create epic related to supporting timeserias accross the PBM and both, sharding cluster support and cloning support should go within that epic.
