   Section	Parameter	Description
   N/A	Schedule Name	The name of the restoration task. DBS generates a task name. We recommend that you set a descriptive name that is easy to identify. Task names do not need to be unique.
   Backup Source Information	Backup Mode	The method that is used to back up data. Set the value to Logical Backup.
   	Database Location	The location of the database that you want to back up. Valid values: User-Created Database with Public IP Address <IP Address:Port Number> Self-managed database that is hosted on Elastic Compute Service (ECS) ApsaraDB for MongoDB Express Connect DB/VPN Gateway/Intelligent Gateway No public network IP: Port's self-built database (accessed through the database gateway) Note If you set the Database Location parameter to ApsaraDB for MongoDB, DBS automatically reads data from the secondary database to perform a full backup. If you set the Database Location parameter to User-Created Database with Public IP Address <IP Address:Port Number> or Express Connect DB/VPN Gateway/Intelligent Gateway, you can specify whether to configure the connection address of the secondary database.
   	Configuration of connection address of standby database	Specifies whether to configure the connection address of the secondary database. If you select Yes for this parameter, DBS reads data from the secondary database to perform a full backup. Note For more information, see Back up a MongoDB instance from a secondary database.
   	Database Type	The type of the database that you want to back up. By default, the database type that you select when you create the backup schedule is used. This parameter is not displayed if you set the Database Location parameter to ApsaraDB for MongoDB.
   	Instance Region	The region where the database that you want to back up is deployed. This parameter is displayed only when you set the Database Location parameter to ECS-Hosted Database, ApsaraDB for MongoDB, or No public network IP: Port's self-built database (accessed through the database gateway).
   	Address	The endpoint that is used to connect to the database that you want to back up. This parameter is displayed only when you set the Database Location parameter to User-Created Database with Public IP Address <IP Address:Port Number>, Express Connect DB/VPN Gateway/Intelligent Gateway, or No public network IP: Port's self-built database (accessed through the database gateway).
   	Port Number	The port number that is used to connect to the database that you want to back up. This parameter is not displayed if you set the Database Location parameter to ApsaraDB for MongoDB.
   	ECS Instance ID	The ID of the Elastic Compute Service (ECS) instance where the database that you want to back up is deployed. This parameter is displayed only when you set the Database Location parameter to ECS-Hosted Database.
   	MongoDB Instance ID	The ID of the ApsaraDB for MongoDB instance where the database that you want to back up is deployed. This parameter is displayed only when you set the Database Location parameter to ApsaraDB for MongoDB. This parameter is displayed only when you set the Database Location parameter to ApsaraDB for MongoDB.
   	Peer VPC	The virtual private cloud (VPC) where the destination database resides. This parameter is displayed only when you set the Database Location parameter to Express Connect DB/VPN Gateway/Intelligent Gateway.
   	Gateway instance ID	The ID of the database gateway. This parameter is displayed only when you set the Database Location parameter to No public network IP: Port's self-built database (accessed through the database gateway).
   	Database Name	The name of the database that you want to back up.
   	Database Account	The username of the account that is used to connect to the database that you want to back up.
   	Password	The password of the database account. After you enter the username and password of the database account, click Test Connection next to the password to check whether the information of the database that you want to back up is valid. If the specified parameters are valid, the Test Passed message is displayed. If the Test Failed message is displayed, click Check next to Test Failed. Modify the information about the instance that you want to back up based on the check results.
   Backup Destination Information	Backup Storage Type	The type of storage that is used to store the backup data. Valid values: DBS Storage (recommended): Backup data is stored in DBS without requiring you to create storage space. You are charged based on the volume of your data that is stored in DBS. For more information about the billing method, see Storage fees. To reduce storage costs, we recommend that you use subscription storage plans. For more information, see Use storage plans. OSS For User: You must create a bucket in the Object Storage Service (OSS) console in advance. For more information, see Create buckets. Note In this example, select DBS Storage (recommended). If you select OSS For user, you must set the OSS Bucket Name parameter.
   	Storage Encryption	The method that is used to encrypt the stored data. Valid values: Encrypted: DBS uses AES-256, one of the advanced encryption standard ciphers, to encrypt the stored data. This is the recommended encryption method. The server-side encryption feature is used in OSS. When you upload an object to OSS, OSS encrypts and stores the object. When you download the encrypted object from OSS, OSS decrypts the object and returns the decrypted object to you. For more information, see Server-side encryption. Non-encrypted: The backup data is not encrypted.

5. In the Edit Backup Objects step, find the database or collection that you want to back up and add it to the Selected section. Then, click Next.
   Note If you selected Logical Backup when you purchased a backup schedule, DBS allows you to back up a single table, a single database, multiple databases, or an entire database instance. You can click Select All in the lower-left corner of the page to select all databases. The database objects that can be backed up vary based on the database types. For more information, see Database engines and features. By default, a backup schedule cannot be used to back up a database that is created after the backup schedule is created. To back up the database, you can add the database to the backup schedule on the Configure Task page of the backup schedule. For more information, see Modify backup objects.
6. In the Configure Backup Time step, set the parameters that are described in the following table and click Next in the lower-right corner of the page.

   Parameter	Description
   Full-scale Backup Frequency	The frequency of the backup schedule. Select Periodic Backup or Single Backup as needed. Note If you set this parameter to Periodic Backup, you must set the Full Data Backup Recurrence and Start At parameters.
   Full Data Backup Recurrence	The days of the week on which DBS runs the backup schedule. You can select one or more days of a week. Select at least one day of the week.
   Start At	The start time of the backup. We recommend that you set a point in time within off-peak hours. Example: 01:00. Note If a previous full data backup is not complete at the start time of the next backup, DBS skips the next backup.
   Incremental Backup	Specifies whether to enable incremental backup. This parameter is displayed only if you set the Full-scale Backup Frequency parameter to Periodic Backup.
   Maximum Concurrent Threads for Full Data Backup	The maximum number of concurrent threads available for a full backup. You can set this parameter to adjust the backup speed. For example, reduce the number of backup threads to minimize impacts on the database. The maximum number of actual concurrent threads varies based on backup schedule specifications. For more information, see How do I change the maximum backup speed?.

7. In the Edit Lifecycle step, configure the lifecycle for full backup data in the Configure Full Data Backup Lifecycle section.
   If you set the Incremental backup parameter to Enable in Step 6, you must configure the lifecycle for incremental backup data. For more information about the lifecycle rules of backup data, see How do I manage the lifecycle rules of backup sets?.
8. After the configurations are complete, click Precheck in the lower-right corner of the page.
9. If the Precheck Passed message appears, click Start Task.
   

   Note When the state of the backup schedule changes to Running, the backup schedule takes effect. You can view the backup task on the Backup Schedules page. For more information, see View a backup schedule.
