Kubernetes Recovery using Kasten K10 platform

This blog post explores the K10 data management platform by Kasten. This is particularly useful in disaster recovery scenarios and migration of applications as we will explore in the post below.

The purpose of this post is to share lessons learned and explore the backup DR with the K10 platform. This exercise is performed for a customer where I should propose strategies DR. One of the requirements is to have a setup area cross Kubernetes active-passive cluster along with the volume of data to replicate the data from source to destination in a regular rhythm.

This is the first part of a series that provides a platform to evaluate the Backup and DR. You can explore https://kubevious.io/blog/post/setting-up-file-based-backup-for-kubernetes-using-velero-and-stash/ to know more about Kubernetes backup.

Some of the key evaluation criteria are:

  • Provision of continuous replication from the source application Kubernetes along with the data
  • Allowance for the snapshot volume to be consistent application and database
  • Inter-regional migration
  • This platform should be expanded
  • Ability to monitor backup and restore jobs. Preferably should allow the monitoring platform via Prometheus
  • Finally, the solution or the gear selection must be original API-centric and cloud itself

About K10

K10 platform truly original and installed on the cluster Kubernetes that need to be supported. The platform is installed as a group CRDS and controller by the graph helmet.

Application

Applications represent a collection of resources such as configmaps, secret, service, and application workloads in a namespace that auto-discovered by K10. A policy can be associated with an application or a subset of resources in applications for backup/restore.

Policy

The policy allows defining actions to be taken when the policy is implemented. Measures can perform snapshots or import from a previous backup is exported. The frequency at which action must be taken, the retention period for backup resource selection are all defined in the policy. This policy also refers to the profile location

K10 Disaster Recovery

The K10 disaster recovery backup from K10 namespace and metadata are accompanied restore point for all applications to allow restoration of the platform K10 itself in case of disaster.

New Roof Prices, Budget-Friendly or Prohibited?

Did you want to get a new roof? The full price of the new roof is uncertain. However, all possible building materials are available and a professional designer can provide you with an estimated cost to replace an old roof. You can also get to know about roofing costs via https://revampo.ca/fr/blog/prix-toiture/.

2020 Roof Replacement Cost - New Roof Installation Prices

Today do-it-yourself kits for roof construction are also offered. One can get this kit which provides the material for installing a glossy asphalt roof in an ordinary house. The price of these kits varies from $ 100 to $ 4,000. People can get their fixtures according to their needs.

Before installing a new roof, the old roof must be removed. Apart from the cost of a new roof, it also costs some money. Removing old material and installing a new roof can be done by a professional for around $ 2,000 to $ 8,000.

Wood shakes are attractive, but it is a tedious maintenance task. They get infected easily and don't last long. It costs around $ 8k to $ 20k. On the other hand, by achieving higher roof quality, longer service life and use of refractory materials, the cost of a new roof can be saved over time. 

Acquiring a new roof also comes at a cost that an ordinary person may never consider when buying a new roof for the first time. Of course, if the foundation that supports the roof is damaged or destroyed, it will need to be repaired.
