Backup and Recovery for Red Hat OpenShift
Red Hat OpenShift Backup and Recovery Solution
OpenShift as a developer-centric platform provides a more lightway, automated and predictable way of deploying virtual environments compared to virtual machines. Stateful applications hold information about the system in which they operate – this can be user session files or temporary data. Their loss is only too real and can cause certain problems for the user, which is why in such cases backup is recommended. Storware vProtect is a certified Red Hat OpenShift Operator, cloud-native data protection solution ready to backup both metadata and persistent volumes attached to pods.
vProtect provides consistent data protection with the ability to recover from a specific point in time. Richness of Backup SLAs gives the option to select the appropriate backup policy and create an optimal backup schedule. Backup SLAs help to easily automate and facilitate the work of data management. Dare to test enterprise-ready and comprehensive data protection solution for OpenShift Container Platform: persistent volumes, deployments/deployment configs (metadata), etcd.
Backup Strategy for OpenShift: Disk attachment with helper pod
Helper Pod to copy data from specific deployment
• crash-consistent backups (file-level or block level when Ceph RBD is used)
• backup of deployment/deployment config metadata and of attached PVs
• PV exclusion
• restore operation recreates deployments and copy data into the appropriate PVs
• option to edit PV configuration during restore
• option to pause deployment during backup for better consistency
Why to backup OpenShift Container Platform?
There are two main reasons to implement backup and recovery services for Red Hat OpenShift: not all containers are stateless (persistent volumes) and it is easier (or even possible) to recover data in the event of a disaster, for example: infrastructure / hardware failures, data center outages, human mistakes, data loss, natural disasters.
Scalability via multi-node architecture
vProtect server – basically it’s a metadata server. It holds all of the configuration files (configuration metadata of backups) and it’s a central management point of vProtect backup solution
vProtect Nodes – they can be deployed as a part of the OpenShift operator or they can reside outside of the OpenShift cluster, so that they can protect multiple clusters or you can protect a cluster with a single node.
