Managing Manual Backups

Precautions

• Manual backups are full backups.
• Backup files are saved as packages in OBS buckets. Upload of backup files and service reads both consume bandwidth, so the upload bandwidth of OBS is limited. The bandwidth of a single node ranges from 20 MB/s to 70 MB/s.

  For better performance, you need to specify appropriate nodes for an instance and take into account the bandwidth for uploading backups.

• The CPU usage may increase 5% to 15% because uploading backups consumes CPU resources.
• The memory usage may increase by about 300 MB during the upload of backups. The increase depends on the instance's data volume. The increased memory mainly caches data during backup upload and service read. After the backup upload is complete, the memory recovers.

Creating a Manual Backup

1. Log in to the GeminiDB console.
2. In the service list, choose Databases > GeminiDB Cassandra API.
3. Create a manual backup.

   Method 1

   On the Instances page, locate the instance that you want to create a backup for and choose More > Create Backup in the Operation column.

   Method 2

   1. On the Instances page, click the instance that you want to create a backup for and click its name.
   2. Choose Backups & Restorations in the navigation pane on the left, click Create Backup.

   Table 1 Parameter description

   Parameter	Description
   DB Instance Name	Must be the name of the DB instance to be backed up and cannot be modified.
   Backup Name	Must be 4 to 64 characters in length and start with a letter. It is case-insensitive and contains only letters, digits, hyphens (-), and underscores (_).
   Description	Contains a maximum of 256 characters and cannot include line breaks or special characters >!<"&'=

5. View the backup status.
   • When the backup is being created, query the backup status on the Backups or Backups & Restorations page. The backup status is Backing up.
   • After the backup is created, the backup status is Completed.

Deleting a Manual Backup

If you do not need a manual backup any longer, delete it on the Backups or Backups & Restorations page.

Deleted backups are not displayed in the backup list.

Deleted backups cannot be recovered. Exercise caution when performing this operation.

Method 2

1. Log in to the GeminiDB console.
2. In the service list, choose Databases > GeminiDB Cassandra API.
3. On the Backups page, locate the backup you want to delete and click Delete in the Operation column.
4. In the displayed dialog box, confirm the backup details and click Yes.
