How to handle Partial snapshots? Drop and initiate a new snapshot?

Hi There,

I want to know the behavior of the snapshot. I have a partial snapshot created(because of primary shard not available for some time)

How to handle this partial snapshot now?

  1. Should I initiate a new snapshot to the same repository? will that create a delta(which were pending from partial snapshot) snapshot with the new name? if yes, will I be able to restore the partial snapshot?

  2. Should I delete the partial snapshot and initiate a new snapshot for that index? in this case, the newly initiated snapshot will be complete one?

  3. Is there any other way to handle this?

Also, is there any way, to handle the snapshot failures, during snapshot process, if primary shard is unavailable? or primary shard is must for snapshot to work?
