/br restore point --storage s3://tmp/br-log-backup6d5183eb-a828-4cac-93b6-c63d9c4f83e1/Log?access-key=xxx&secret-access-key=xxx&endpoint=http%3a%2f%2fminio-peer%3a9000&force-path-style=true --pd http://downstream-pd.brie-acceptance-pitr-tps-7864765-1-953:2379 --restored-ts 458156326901252170 --full-backup-storage s3://tmp/br-log-backup6d5183eb-a828-4cac-93b6-c63d9c4f83e1/Full?access-key=xxx&secret-access-key=xxx&endpoint=http%3a%2f%2fminio-peer%3a9000&force-path-style=true --concurrency=8 --check-requirements=false
