Data Management:Physically back up and restore a MySQL database hosted on a third-party cloud or a self-managed MySQL database

Create a backup schedule

For more information, see Create a backup schedule.

Configure a backup schedule

1. Log on to the DMS console V5.0.

2. In the top navigation bar, choose Security and Specifications (DBS) > Data Disaster Recovery (DBS) > Backup Plan.

   Note

   If you use the DMS console in simple mode, move the pointer over the icon in the upper-left corner of the DMS console and choose All Features > Security and Specifications (DBS) > Data Disaster Recovery (DBS) > Backup Plan.

3. On the Backup Schedules page, find the backup schedule that you want to configure and click Configure Backup Schedule in the Actions column.

4. In the Configure Backup Source and Destination step, configure the backup source and destination, and click Next in the lower-right corner of the page.

   

   Section	Parameter	Description
   N/A	Schedule Name	The name of the backup schedule. Data Disaster Recovery automatically generates a backup schedule name. We recommend that you enter a descriptive name that is easy to identify. Backup schedule names do not need to be unique.
   Backup Source Information	Backup Mode	The method that is used to back up data. By default, the backup method that you select when you purchase the backup schedule is used. In this example, Physical Backup is selected.
   	Backup Type	The type of the backup. Default value: Native physical backup.
   	Instance Region	The region in which the source database resides. The Backup Gateways and database instance must reside in the same region.
   	Backup Gateway	The backup gateway that is installed to back up data. For more information, see Install a backup gateway.
   	Database Type	The type of the source database. Default value: MySQL.
   	Address	The IP address that is used to connect to the source database. Default value: 127.0.0.1.
   	Port Number	The port number that is used to connect to the source database. Default value: 3306.
   	Database Account	The username of the account that is used to connect to the source database. The account must have specific permissions to back up the database. For more information, see Account permissions.
   	Password	The password of the account that is used to connect to the source database.
   	Compliance warranty regarding cross-border data transfers	Read and agree to the compliance commitment by selecting the check box.
   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 Data Disaster Recovery without the need to create an Object Storage Service (OSS) bucket. You are charged based on the volume of your data that is stored in Data Disaster Recovery. For more information about the billing method, see Storage fees. OSS For User: You must create a bucket in the OSS console in advance. For more information, see Create buckets. Note In this example, DBS Storage (recommended) is selected. If you select OSS For User, you must configure the OSS Bucket Name parameter. Only the Standard storage class is supported. If you want to store a large amount of data, we recommend that you purchase a subscription storage plan to offset Data Disaster Recovery built-in storage fees. Storage plans are more cost-efficient than the pay-as-you-go billing method.
   	OSS Bucket Name	The name of the OSS bucket that you want to use to store data. Note This parameter is displayed only if you set the Backup Storage Type parameter to OSS For User.
   	Storage Encryption	Specifies whether to encrypt the backup data. Valid values: Encrypted: recommended. Data Disaster Recovery uses AES-256 to encrypt data. The server-side encryption feature is used in OSS. When you upload an object to a bucket for which server-side encryption is enabled, 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, Back Up Entire Instance is selected by default. Click Next.

   Note

   To perform a physical backup, you must back up the Back Up Entire Instance. In this case, the permissions and stored procedures are also backed up.

6. In the Configure Backup Time step, configure 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. Valid values: Periodic Backup and Single Backup. Note If you select Periodic Backup, you must configure the Full Data Backup Recurrence, Start At, and Real-Time Transaction Log Backup parameters.
   Full Data Backup Recurrence	The days of the week on which Data Disaster Recovery 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 specify a point in time during off-peak hours. Example: 01:00. Note If a previous full data backup is not finished at the start time of the next backup, Data Disaster Recovery skips the next backup.
   Incremental Backup	Specifies whether to enable the incremental backup feature. Note This parameter is displayed only when you set the Full-scale Backup Frequency parameter to Periodic Backup. If you enable incremental backup, make sure that the binary logging feature is enabled for the database that you want to back up.
   Real-time Log Backup	Specifies whether to enable log backup. Note 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, you can reduce the number of backup threads to minimize impacts on the database. Note The maximum number of actual concurrent threads varies based on backup schedule types. For more information, see How do I change the maximum backup speed?
   Read speed limit	The limit on the disk I/O. You can specify the limit based on your business requirements. Default value: 0, which indicates that the disk I/O is not limited.
   Backup network speed limit	The limit on the network bandwidth. You can specify the limit based on your business requirements. Default value: 0, which indicates that the network bandwidth is not limited.
   Transaction Log backup interval	The interval at which an incremental backup is performed. Data Disaster Recovery performs the incremental backup based on your configurations. If you set the interval to 10 minutes, Data Disaster Recovery performs an incremental backup every 10 minutes. Note This parameter is displayed only if you set the Incremental Backup parameter to Enable.
   Enable compression	Specifies whether to enable compression during backup. Valid values: Enable: recommended. Data is compressed during backup to reduce storage space. Disable: Data is not compressed during backup.
   Compression algorithm	The algorithm that is used to compress data. Valid values: GZIP (default) LZ4 Note This parameter is displayed only if you set the Enable compression parameter to Enable.

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 preceding configurations are complete, click Precheck in the lower-right corner of the page.

9. If the Precheck Passed message appears, click Start Task.

   

   Note

   • If the state of the backup schedule changes to Running, the backup schedule takes effect.

   • If an exception or error occurs when you start the backup schedule, troubleshoot the exception or error at the earliest opportunity. For more information, see How do I fix errors for an abnormal backup schedule? If your issue persists after you use the solution that is provided in the preceding topic, contact technical support in the DingTalk group (ID: 35585947).
