Hi, I have not been inside Veeam for a while. I am getting errors as in the snapshot below:

I understand it is complaining about storage space for backups but I am trying to zero in on what to attack first here. The one that interests me is “Unable to apply retention policy: failed to delete backup files error…...is locked by running session xxx-xxx [Instant recovery]. Is Veeam just too busy to start the backup because it could not apply retention policy? Not sure which item to investigate first.
