Does percona's hot backup do a backup of sharded cluster with multiple configsvrs and shards?

I have a sharded instance containing total size of 3.5 TB.
I’m trying to do a hot backup of it using method mentioned here
But I’m not sure if it can handle the sharded instance as well.
Also, Is there a way to restore a backup directly from s3 bucket? just like we can stream backup directly to S3.
Can someone please clarify these.
