------------------------------------------------------------------
Hey [~vinayakhegde], this looks good overall. I just have two questions:
# In Section 3 "Backup and WAL Coverage", the last sentence says, "If the user
requested only validation, return success at this point." How does the user
request only validation? I can't tell what command line arg is used for that
when I look at the command description at the top of the ticket.
# Why is fm considered unknown/unrecorded? I was expecting that we could get
the time of the snapshot from the snapshot itself.
