Using Current Browser

Scenarios

DDS supports backup downloading, giving users greater control over their data. It allows you to manage the backup lifecycle independently while meeting enterprise-level requirements for disaster recovery, migration, and compliance. You can use a browser to download a manual or an automated backup to a local device for backup or restoration.

Precautions

• Cluster backup files cannot be downloaded using a browser.
• Backups downloaded from the DDS console are all full backups.

Procedure

1. Log in to the management console.
2. Click in the upper left corner and select a region and a project.

4. In the navigation pane on the left, choose Backups.
5. On the Backups page, click the Clusters, Replica Sets, or Single Nodes tab, locate the available backup you want to download and click Download in the Operation column.

7. After the backup file is downloaded, decompress it using LZ4.

   Run the following command to decompress the backup file:

   lz4 -d $1 | tar -xC $2

   $1: indicates the downloaded backup file.

   $2: indicates the directory to which the backup file is decompressed.

8. You can restore data locally as required.
