Chapter 8. Backing Up and Restoring Data Grid Clusters
Create archives of Data Grid resources that include cached entries, cache configurations, Protobuf schemas, and server scripts. You can then use the backup archives to restore Data Grid Server clusters after a restart or migration.
Prerequisites
- Start the Data Grid CLI.
- Connect to a running Data Grid cluster.
8.1. Backing Up Data Grid Clusters Copy linkLink copied to clipboard!
Create backup archives in .zip
format that you can download or store on Data Grid Server.
Prerequisites
Backup archives should reflect the most recent cluster state. For this reason you should ensure the cluster is no longer accepting write requests before you create backup archives.
Procedure
- Create a CLI connection to Data Grid.
Run the
backup create
command with the appropriate options, for example:Back up all resources with an automatically generated name.
[//containers/default]> backup create
[//containers/default]> backup create

8.2. Restoring Data Grid Clusters from Backup Archives Copy linkLink copied to clipboard!
Apply the content of backup archives to Data Grid clusters to restore them to the backed up state.
Prerequisites
- Create a backup archive that is either local to the Data Grid CLI or stored on Data Grid Server.
- Ensure that the target container matches the container name in the backup archive. You cannot restore backups if the container names do not match.
Procedure
- Create a CLI connection to Data Grid.
Run the
backup restore
command with the appropriate options.Restore all content from a backup archive accessible on the server.
[//containers/default]> backup restore /some/path/on/the/server
[//containers/default]> backup restore /some/path/on/the/server
Copy to Clipboard Copied! Toggle word wrap Toggle overflow Restore all content from a local backup archive.
[//containers/default]> backup restore -u /some/local/path
[//containers/default]> backup restore -u /some/local/path
Copy to Clipboard Copied! Toggle word wrap Toggle overflow Restore only cache content from a backup archive on the server.
[//containers/default]> backup restore /some/path/on/the/server --caches=*
