Data backup and recovery is an integral part of the business continuity plan and developing a data backup strategy begins with finding out which data to backup, selecting and implementing hardware and software backup procedures, scheduling and conducting backups and periodically validating that data has been accurately backed up.It is to be performed frequently to ensure the safe run of business.In other words, data backup and disaster recovery solutions keep businesses safe when trouble strikes.
There is no way to prevent a cyber attack, natural disaster,technical malfunction or an uncontrollable human error but you can protect your business from costly data loss by investing in a solution that aids in data backup and disaster recovery.
Azure Backup & Site Recovery
Unlike traditional backup solutions,Azure delivers all the advantages of a powerful and affordable cloud backup solution. Azure Backup is the perfect solution you can use to backup and restore all your data in the Microsoft Cloud. It replaces your existing on-premises off-site backup solutions with a cloud-based solution. Azure is reliable, secure and cost-effective and helps in protecting assets that runs in the cloud. Azure Backup provides recovery services built on a superlative infrastructure that is scalable, durable and also highly available.
Why use Azure Backup?
|Automatic storage management||No capital expenditure is needed for on-premises storage devices. Azure Backup automatically allocates and manages backup storage, and it uses a pay-as-you-use consumption model|
|Unlimited scaling||Take advantage of high availability guarantees without the overhead of maintenance and monitoring. Azure Backup uses the underlying power and scale of the Azure cloud, with its non intrusive auto scaling capabilities|
|Multiple storage options||
Choose your backup storage based on need:
|Unlimited data transfer||There is no charge for any egress (outbound) data transfer during a restore operation from the Backup vault. Data inbound to Azure is also free. Works with the import service where it is available.|
|Data encryption||Data encryption allows for secure transmission and storage of customer data in the public cloud. The encryption passphrase is stored at the source, and it is never transmitted or stored in Azure. The encryption key is required to restore any of the data, and only the customer has full access to the data in the service.|
|Application-consistent backup||Application-consistent backups on Windows help ensure that fixes are not needed at the time of restore, which reduces the recovery time objective. This allows customers t quickly return to a running state.|
|Long-term retention||Rather than pay for off-site tape backup solutions, customers can back up to Azure, which provides a compelling tape-like solution at a low cost.|
Azure Site Recovery
Every organization needs a disaster recovery solution that keep data safe and accessible during planned and unplanned downtime and recovers to normal working conditions at the earliest.
Azure has two different deployment models for creating and working with resources;They are: Azure Resource Manager model and the classic services management model. Azure also has two portals – the Azure classic portal that supports the classic deployment model, and the Azure portal with support for both the classic and Resource Manager models.
- Site Recovery is available in both the classic portal and the Azure portal.
- In the Azure classic portal, you can support Site Recovery with the classic services management model.
- In the Azure portal, you can support the classic model or Resource Manager deployments.
Why deploy Site Recovery?
- Simplify BCDR—You can handle replication, fail over and recovery of multiple workloads in a single location in the Azure portal. Site recovery orchestrates replication and fail over but doesn't intercept your application data or have any information about it.
- Provide flexible replication—Using Site Recovery, you can replicate workloads running on supported Hyper-V VMs, VMware VMs, and Windows/Linux physical servers.
- Perform easy replication testing—Site Recovery provides test fail overs to support disaster recovery drills, without affecting production environments.
- Fail over and recover— You can run planned fail overs for expected outages with a zero-data-loss, or unplanned fail overs with minimal data loss (depending on replication frequency) for unexpected disasters. After fail over, you can fail back to your primary sites. Site Recovery provides recovery plans that can include scripts and Azure automation workbooks, so that you can customize fail over and recovery of multi-tier applications.
- Eliminate a secondary data center—You can replicate workloads to Azure, rather than to a secondary site. This eliminates the cost and complexity maintaining a secondary data center Replicated data is stored in Azure Storage, with all the resilience that provides. VMs are created with the replicated data when fail over occurs.
- Integrate with existing BCDR technologies—Site Recovery integrates with other BCDR features. For example, you can use Site Recovery to protect the SQL Server backend of corporate workloads, including native support for SQL Server AlwaysOn, to manage the fail over of availability groups.
