A very strange thing happened: my entire cluster, including all the PVCs, was deleted, resulting in no data. I had been running a cronjob every night using PSMDB backup. When I tried to restore my data using the restore.yaml file, I successfully retrieved the backup. However, the restored database is larger than the original one. Additionally, the restore process threw errors while retrieving the backup. I don’t understand how the data size could be larger despite these errors.Attaching the error of the same
