Error: When restoring DB for replica set using MMS point in time, we have this error:

“You are attempting to restore to a version no longer accessible for restore. Point In Time restores are only available for the last 24 hours.”

Causes: Allow point-in-time restores going back (or oplog stored time) is set to more than 1 day but the snapshots interval is more than 12 hours (min 12 hours for Point in Time to work)

Solutions: Allow point-in-time restores going back should be set to more than 1 days but the snapshot should be also captured at least every 12 hours

Notes: Point in time only works for replica set. If you are using shard cluster, you should use checkpoint restore which allows to restore to any 15 mins point in time.
