Backups

CLOUD

Overview​

Dragonfly Cloud supports manual on-demand backups and recurring scheduled backups. To ease the process of migrating data, importing Redis backups (RDB files) from a remote storage system is also supported.

Existing backups in your Dragonfly Cloud account can be restored to an active data store at any time.

For clustered (multi-shard) data stores, please review the cluster backup limitations before restoring.

Manual On-Demand Backups​

To create a manual on-demand backup, follow the steps below:

  • Click the three-dot menu () in the data store row.
  • Expand the Backups menu and select Manual, the backup drawer will open on the right.
  • Enter a meaningful Description that will help you identify the backup later for restoration.
  • Set the Retention period to the number of days after which the backup will be deleted automatically.
  • Click Create.

View created backups under the Account > Backups tab.

Scheduled Backups​

To set a recurring scheduled backup, follow the steps below:

  • Click the three-dot menu () in the data store row.
  • Expand the Backups menu and select Schedule, the backup drawer will open on the right.
  • Set the Backup Policy to Enabled, the Schedule options will appear.
  • Select the day(s) of the week (or Every Day) and hours of the day (or Every Hour) to set when the scheduled backup should be created.
  • Set the Retention period to the number of days after which the backup will be deleted automatically.
  • Click Apply.

You can edit the backup schedule anytime.

Restoring from Backup​

To restore a backup in an existing data store, follow the steps below, with caution:

  • CAUTION: This cannot be undone. It will clear all data in the data store and replace it with the backup.
  • Click the three-dot menu () in the row of the data store you would like to restore to.
  • The Restore Backup drawer will open on the right.
  • Make 100% sure you select the correct backup from the dropdown.
  • Click Restore.

Cluster Datastore Backups​

Dragonfly Cloud supports backups for clustered (multi-shard) data stores. A cluster backup captures the full dataset distributed across all shards at the point in time the backup was taken.

Limitations​

  • Shard count must match on restore: The target data store must have the same number of shards as the data store at the time the backup was created. Restoring a cluster backup to a data store with a different shard count is not supported.
  • Shard distribution must be identical: Data is partitioned across shards by hash slot ranges. Because each shard's backup encodes data bound to a specific slot range, the slot layout of the target data store must exactly match the original. A mismatch will result in a restore failure.
  • Cross-tier restore is not supported: A backup taken from a clustered data store cannot be restored to a single-shard (non-clustered) data store, and vice versa.

CAUTION: Before initiating a restore, verify that the target data store's shard count and configuration match the data store that the backup was originally taken from.

Viewing and Deleting Backups​

  • You can view all backups under the Account > Backups tab.
  • To delete a backup, click the three-dot menu () in the backup row and click Delete.

Importing Redis Backups (RDB)​

You can import Redis backups (RDB files) to Dragonfly Cloud from a remote storage system. Once imported, the backup will be visible under the Account > Backups tab and will be available for restoration.

To import a Redis backup, follow the steps below:

  • Navigate to the Account > Backups tab.
  • Click on the +Import RDB button.
  • Enter a meaningful Description that will help you identify the backup later for restoration.
  • Set the Retention period to the number of days after which the imported backup will be deleted automatically.
  • Enter the HTTP Source URL of the RDB file to import.
  • Chose the Target Cloud to import to, must match the cloud of the data store you want to restore to.
  • Chose the Target Region to import to, preferably match the region of the data store you want to restore to.
  • Click Import.
  • Once the backup is visible in status Ready, you can restore it to a data store as described above.

RDB File Accessibility​

  • The imported RDB file URL must be publicly accessible via HTTP(S) over the internet.
  • It is most secure to use a signed URL with a short expiration time to import the RDB file.
  • See AWS S3 presigned URLs or Google Cloud Storage signed URLs for more information.
  • Otherwise, you can generate a long random URL and delete the file after import to ensure security.
