The minimum amount of time that snapshots should be retained
You can protect recent snapshots from deletion, by specifying the minimum number of
hours that snapshots of any type should be retained. After this amount of time has
elapsed, the snapshots will be deleted according to the retention policy.
The default value is 24 hours, meaning that snapshots created less than 24 hours ago will
not be deleted.
