Configuring Management Data Backup Storage

Context

• When backing up eBackup management data, calculate the shared storage capacity in advance. If the shared storage capacity is not enough, the latest backup job will fail. The shared storage capacity is related to the backup data retention policy:
  • If Daily Backup is selected

    The capacity of shared storage for storing backup management data = [(Number of yearly backups + Number of monthly backups + Number of weekly backups + Number of daily backups +1) x 10 + 15] GB.

    • For example, if the default retention policy is used, the capacity of shared storage for storing backup management data = [(0 + 1 + 1 + 1 + 1) × 10 + 15] GB = 55 GB.
    • If Number of retained copies generated in yearly backup is set to Permanent, planned capacities depend on the number of years for saving backups. The capacity of shared storage for storing backup management data = [(Number of years for saving backups + Number of monthly backups + Number of weekly backups + Number of daily backups + 1) × 10 + 15] GB.
  • If Hourly Backup is selected

    The capacity of shared storage for storing backup management data = [(Number of yearly backups + Number of monthly backups + Number of weekly backups + Number of daily backups + Number of hourly backups + 1) x 10 + 15] GB.

    • For example, if the default retention policy is used, the capacity of shared storage for storing backup management data = [(0 + 1 + 1 + 1 + 1 + 1) × 10 + 15] GB = 65 GB.
    • If Number of retained copies generated in yearly backup is set to Permanent, planned capacities depend on the number of years for saving backups. The capacity of shared storage for storing backup management data = [(Number of years for saving backups + Number of monthly backups + Number of weekly backups + Number of daily backups + Number of hourly backups + 1) × 10 + 15] GB.
• Configure separate backup storage space for eBackup management data.
• You are advised to use the purchased hybrid cloud backup vault for S3 backup storage.

Prerequisites

• You have planned the capacity of the S3 shared storage. The capacity of the shared storage must meet the requirements. Or, the backup job will fail. For details, see Context.
• You have obtained the domain name or IP address of the S3 storage service plane, and the name, AK, and SK of the bucket that stores backup data.

Procedure

1. Log in to the eBackup management system using the admin account.

   For details, see Logging In to eBackup.

2. In the navigation tree, choose > Configuration > Management Data Backup.
3. Click Set Backup Storage.
4. Configure the backup storage of the eBackup management data.
   Table 1 describes the parameters.

   

   Do not use the same bucket as the backup storage of the management data and user VM data. Or, backup jobs will fail.

   Table 1 Backup storage (S3) parameters

   Parameter	Description	Setting Rule
   Type	Type of the backup storage for the management data	S3
   Protocol	Network protocol for the communication between the eBackup management system and S3 storage. Options include HTTP and HTTPS.	If HTTPS is specified, import a valid certificate to verify the S3 storage. Obtain the certificate from the S3 storage administrator in advance. Security risks arise if the protocol is set to HTTP. You are advised to select the HTTPS protocol.
   AK	Access Key (AK) confirms the identity of a user accessing the object-based storage system.	-
   SK	Secret Key (SK) allows a user to access an object-based storage system. Secret access keys and access key IDs are in one-to-one match.	-
   Path	Path to access the S3 storage	IPV4 path format: IP address or domain name:/bucket name IP address and domain name indicate the service IP address and the domain name of the object-based storage system, respectively. A bucket name contains 3 to 255 characters and can contain letters, digits, and special characters. Special characters include periods (.), hyphens (-), and underscores (_).
   Identifier	Name of a subdirectory saving management data backups, which differentiates the management data backups of different eBackup systems	An identifier contains 1 to 64 characters and can contain only letters, digits, underscores (_), and hyphens (-).
   If a subdirectory with the same name already exists, the system uses the existing subdirectory forcibly.	Whether to write data if a subdirectory with the same name already exists If selected The backup data will be written to the subdirectory even if a subdirectory with the same name exists.l NOTE: If multiple eBackup systems use the same backup subdirectory, management data backups may be unavailable. Use a subdirectory for each eBackup system. If not selected You cannot create a backup subdirectory if a subdirectory with the same name already exists. In this case, use a different name for the subdirectory.	-

5. Click OK.

   After the configuration is completed, the backup storage configuration status will be shown to the right of the Set Backup Storage button.

   • : The configuration is in progress.
   • No icon: The configuration is successful.
   • : The configuration failed.
   

   If the configuration fails, click Set Backup Storage and reconfigure.

6. (Optional) Configure a backup policy for the management data.
   

   To ensure the system database security of the backup software, you are advised to back up the database periodically. The system performs full backups for every time.

   • Click Automatic Backup Settings. In the dialog box that is displayed, configure an automatic backup policy as prompted.
     • If Daily Backup is selected, the default system settings are as follows.
       Figure 1 Setting daily backup
       
     • If Hourly Backup is selected, the default system settings are as follows.
       Figure 2 Setting hourly backup
       
     • Hourly backup: Backup generated every n hour(s) in the system.
     • Daily backup: first backup generated per day.
     • Weekly backup: first backup generated on Monday per week.
     • Monthly backup: first backup generated on the first Monday per month.
     • Yearly backup: first backup generated on the first Monday per year.
     

     You are advised to set the backup time to off-peak hours to reduce impact on services, for example, 00:00 to 02:00.

     After the automatic backup policy is configured, restart the eBackup process on the backup server to make the policy take effect. For details, see "Restarting the eBackup Process."

     If the backup time overlaps (for example, monthly backup and weekly backup are both performed on Monday), the system performs backups based on the backup policy with the highest priority. The priorities of the following backup policies descend: yearly backup > monthly backup > weekly backup > daily backup > hourly backup.

   • Click Immediate Manual Backup. The backup job is executed immediately.
     

     You are advised to manually back up the system database immediately before and after a major operation, such as an upgrade and critical data modification.

Follow-Up Operations

If you need to delete unnecessary backup data, you can find and delete the data according to package names of backup data. The file name is in the format of [Backup data type][Backup type][Service name][Year][Month][Day][Minute][Second][Backup period][No.].db. The following uses FMTEBACKUP20170811110307X001.db as an example.
