Cloud Backup:Create a backup plan for an OSS bucket

Precautions

Procedure

To create a backup plan for an OSS bucket, perform the following steps:

1. Log on to the Cloud Backup console.

2. In the left-side navigation pane, choose Backup > OSS Backup.

3. In the top navigation bar, select the region where the OSS bucket resides.

4. On the Backup Plans tab, click Backup Bucket.

5. In the Create Backup Plan panel, configure the parameters and click OK.

   Note

   You can use each backup plan free of charge for 30 days, which starts from the day when the backup plan is created. For example, if you create a backup plan on February 14, 2020, you can use the backup plan free of charge until March 15, 2020.

   This topic describes how to configure a backup plan in paid mode. You can follow a similar procedure to configure a backup plan in free mode.

   1. Click Switch to Paid Plan.

   2. Configure the basic parameters described in the following table.

      Important

      • If the selected region supports backup policies, you can set a backup plan only by associating it with the backup policy. Cloud Backup periodically backs up OSS objects based on the backup policy.

      • To view the regions that support backup policies, click Policy Center in the left-side navigation pane of the console. For more information about how to create a backup policy, see Create a backup policy.

      Parameter	Description
      Source OSS Bucket	The name of the OSS bucket that you want to back up. Select an OSS bucket from the drop-down list.
      Backup Vault
      Backup Vault	The backup vault to which you want to store the backup data. Valid values: Create Vault: If you select this option, specify a name for the backup vault in the Vault Name field. If you do not configure this parameter, a random name is specified. Select Vault: If you select this option, select a backup vault from the Vault Name drop-down list. To maximize the redundancy of your backup data, Cloud Backup uses ZRS-enabled backup vaults by default in regions that support ZRS-enabled backup vaults. If only LRS-enabled backup vaults are available in the region where the backup vaults are located, Cloud Backup uses LRS-enabled backup vaults. You do not need to manually select a backup vault type.
      Vault Name	The name of the backup vault.
      Vault Resource Group	This parameter is required only if you set the Backup Vault parameter to Create Vault. This parameter specifies the resource group to which the backup vault belongs. You can use resource groups to manage resources owned by your Alibaba Cloud account. Resource groups help you simplify the resource and permission management of your Alibaba Cloud account. For more information, see Create a resource group.
      Backup Vault Encryption Method	This parameter is required only if you set the Backup Vault parameter to Create Vault. This parameter specifies the method that is used to encrypt the data in the backup vault. Cloud Backup-managed (default): You can use the default encryption method of Cloud Backup. KMS: You can use Key Management Service (KMS) to encrypt the data that is stored in the backup vault. If you select this option, you must specify the KMS KeyId parameter. Important If you enable KMS-based encryption, you cannot modify a KMS key. Before you can use the KMS key to encrypt the data in the backup vault, you must create a key ID in the KMS console. For more information, see Create a CMK.
      Basic Settings
      Plan Name	The name of the backup plan. If you do not configure this parameter, a random name is specified.
      Source Path	The prefix in the names of the objects that you want to back up from the OSS bucket. By default, no prefix is specified and all objects in the root directory of the OSS bucket are backed up.
      Time Settings
      Start Time	The time at which the backup plan starts. The time is accurate to seconds.
      Backup Interval	The interval at which incremental backup is performed. Default value: 1 day. Unit: days or weeks.
      Retention Policy	The retention policy of the backup data. Valid values: Limited (default): The backup data is retained for a specified period of time. If you select Limited, you must set the Retention Period parameter. Permanent: The backup data is permanently retained. Important After you create a backup vault and store backup data, you are charged for the usage of the backup vault. For more information, see Billing methods and billable items.
      Retention Period	This parameter is required only if you set the Retention Policy parameter to Limited. This parameter specifies the period of time for which the backup data is retained. Default value: 2 years. Unit: days, weeks, months, or years.
      Keep At Least One Backup Version	We recommend that you turn on the switch. If you turn on the switch, the latest backup version generated by the backup plan is not deleted due to the expiration of the retention period or accidental operations. This prevents the risk that no backup version is available for restoration due to reasons such as improper backup plan settings. For more information, see Keep at least one backup version.
      Performance Optimization
      Use OSS Inventory	Specifies whether to enable the OSS inventory feature to back up data from the OSS bucket. Default value: No. If you need to back up a large amount of data from an OSS bucket, we recommend that you enable this feature. For more information, see Use an OSS inventory list to create a backup plan for a large amount of OSS data.

   After the backup plan is created, Cloud Backup backs up OSS objects from the specified start time at the specified interval.
