   @nischalnischal2020 please check the newly created PR #9239 to address an 
issue which I've observed while checking your issue here.
   
   The issue I've observed is not while taking the snapshot but while creating 
the template from the snapshot (stack trace also refers the same).
   
   I could not reproduce the original issue of failed snapshot showing as 
backedup state rather than error (it might have already fixed after 4.17.2), 
but I saw another serious issue.
   
   The issue is whenever a snapshot is used to create a template or volume and 
if there is failure in backing up the snapshot to the secondary store and as 
part of handling that failure MS is deleting the snapshot in primary storage 
itself.
   
   These changes are introduced as part of the PR 
https://github.com/apache/cloudstack/pull/5297
   
       Create a snapshot of a volume (set snapshot.backup.to.secondary = False)
       Create a template from that snapshot
       As part of the creation, MS first tries to backup the snapshot to the 
secondary storage
       I've made it fail
       MS recognized the failure and as part of failure it is deleting the 
snapshot on the primary storage (also marking the snapshot_store_ref entry for 
primary store role as "Destroyed")
