ETCD Snapshot restore Error

Kubernetes
#1

I successfully took the backup of etcd and restore failed with below mentioned exception.

root@k8s-control:/# sudo ETCDCTL_API=3 etcdctl snapshot restore /home/cloud_user/etcd_backup.db --data-dir /var/lib/etcd-from-backup
Error: expected sha256 [32 77 132 49 156 109 182 253 182 245 237 211 200 190 41 107 57 99 183 199 146 162 169 29 9 111 118 49 24 15 140 125], got [68 232 59 125 114 103 19

#2

sudo ETCDCTL_API=3 etcdctl snapshot restore /home/cloud_user/etcd_backup.db --data-dir /var/lib/etcd-from-backup --skip-hash-check=true

with --skip-hash-check=true it works perfectly fine. I am not sure why this parameter is required. I understand this is not comparing hash when restoring

etcd skip hash during restore

from backup.
