Hi guys,

I am trying to do a restore test of one of our older clusters on a new one and I cannot get `pbm config --force-resync` to work correctly.  
Both source and destination replicasets are running mongodb 4.0.24 and pbm 2.0.2, they have the same exact backup storage setup.

When I run `pbm config --force-resync` on the destination cluster , `pbm logs` shows that the operation starts and succeeds, however no entries are created in the pbmBackups collection. If I manually insert a backup entry from the old cluster into the new cluster, `pbm list` shows it and it is possible to restore from it. However if I rerun `pbm config --force-resync` the pbmBackups collection becomes empty again.  
Is there a way to get more debug information from force-resync to understand why this is happening ?

Thanks a lot
