Restore
Restoring is a manual process and will be used to restore any backed up data from any S3-compatible data store.
Restoring from backup
- 
Pause all Percona XtraDB Cluster Server tasks.
dcos percona-pxc-mysql --name=percona-pxc-mysql debug pod pause <pod-name> -t <task-name> - 
Start the restore plan.
dcos percona-pxc-mysql plan start restore -p ACCESS_KEY_ID=<ACCESS_KEY> -p SECRET_ACCESS_KEY=<SECRET_ACCESS_KEY> - 
Resume all Percona XtraDB Cluster Server tasks sequentially such that a node is resumed only when its predecessor node has arrived in synced state:
dcos percona-pxc-mysql --name=percona-pxc-mysql debug pod resume <pod-name> -t <task-name> 
This will restore the backed up PXC data to your existing cluster.
