    Modify the restore period for a temporarily restored Amazon EBS snapshot
When you restore a snapshot temporarily, you must specify the number of days for which 
        the snapshot is to remain restored in your account. After the restore period expires, the 
        snapshot is automatically removed from the standard tier.
You can change the restore period for a temporarily restored snapshot at any time.
You can choose to either increase or decrease the restore period, or you can change the 
        restore type from temporary to permanent.
If you change the restore period, the new restore period is effective from the current 
        date. For example, if you specify a new restore period of 5 days, the snapshot 
        will remain restored for five days from the current date.
You can end a temporary restore early by setting the restore period to 1 day.
If you change the restore type from temporary to permanent, the snapshot copy is deleted 
        from the archive tier, and the snapshot remains available in your account until you manually 
        re-archive it or delete it.

                restore-snapshot-tier command. For --snapshot-id, specify the ID of the 
                snapshot that you previously temporarily restored. To change the restore type from temporary to 
                permanent, specify --permanent-restore and omit --temporary-restore-days. 
                To increase or decrease the restore period, omit --permanent-restore and for

              The following command changes the restore period for the specified snapshot  
                to 10 days.
             
            aws ec2 restore-snapshot-tier \
    --snapshot-id snap-0abcdef1234567890 \
    --temporary-restore-days 10
            The following is example output.
            {
    "SnapshotId": "snap-0abcdef1234567890",
    "RestoreDuration": 10,
    "IsPermanentRestore": false
}
            
             
              Example: Change restore type to permanent

                from temporary to permanent.
             
            aws ec2 restore-snapshot-tier \
    --snapshot-id snap-0abcdef1234567890 \
    --permanent-restore
            The following is example output.
