Is there any way to backup all the tables from bigtable instance at once?

Question

we have created a single instance and we want to backup all the tables in that single instance using gcloud command as we have created a pipeline to do that backup thing but while running the backup command gcloud bigtable backups create BACKUP_ID --instance=INSTANCE_ID --cluster=CLUSTER_ID --table=TABLE_ID --async --expiration-date=EXPIRATION_DATE | --retention-period=RETENTION_PERIOD

we are able to backup only one table and after that we are getting an error

 ERROR: (gcloud.bigtable.backups.create) {
  "code": 6,
  "details": [

        },

        }
      ]
    }
  ],

}

Answer 1

Based on the error message you received:

"message": "Backup bigtable-backup already exists."

It seems like you already have a BACKUP_ID named bigtable-backup.

BACKUP_ID should be unique. As stated in the Cloud Bigtable documentation,

BACKUP_ID: The ID you assign to the backup.

Try using a different BACKUP_ID on your succeeding backups.
