Azure Backup is a scalable solution with zero-infrastructure which protects your data irrespective of its location. Azure backup for unstructured data includes backing up files, folders, and system state data.
What is the purpose of Azure Data Lake Storage for unstructured data?
Azure Data Lake Storage is an enterprise-wide hyper-scale repository for big data analytic workloads. It allows you to store and analyze petabyte-size files and trillions of objects with unlimited instant scalability.
What is Blob Storage on Azure?
Azure Blob Storage is a service for storing large amounts of unstructured data, such as text or binary data, that can be accessed from anywhere in the world via HTTP or HTTPS.
How is Azure Storage Service Encryption for Data at Rest used?
Azure Storage Service Encryption for Data at Rest helps you secure your data to meet the organizational security and compliance commitments. It uses service-managed keys to encrypt data before persisting it to Azure Storage.
What is Geo-Redundant Storage (GRS) in Azure?
Geo-Redundant Storage (GRS) is a replication option for Azure Storage designed to provide at least 99.99999999999999% (16 9’s) durability of objects over a given year by replicating your data to a secondary region that is hundreds of miles away from the primary region.
On what principle does Azure Data Factory work?
Azure Data Factory works on the Extract, Transform and Load (ETL) principle. It has the capability to ingest, prepare, transform, and enrich the data both on-premises and in the cloud.
Are backups mandatory for Azure File storage recovery?
No. Azure provides soft delete, share snapshot, and Backup features for Azure Files to fulfill the different level of recovery requirement. However, for a comprehensive recovery strategy, Azure recommends Backup with Azure file shares.
What is the Recovery Time Objective (RTO)?
The Recovery Time Objective (RTO) is the time duration within which a business process must be restored after a service disruption to avoid unacceptable consequences associated with a break in business continuity.
What is the Recovery Point Objective (RPO)?
The Recovery Point Objective (RPO) is the maximum acceptable amount of data loss measured in time. It defines the age of files that must be recovered from backup storage for normal operations to resume if a computer system or network failure occurs.
Is there a way to automate Azure backup?
Yes, Azure Backup provides the backup policy feature to allow you to create a policy for a backup schedule and retention range, and then assign the policy to the virtual machines that need to be backed up.
What does Azure Data Box do?
Azure Data Box is used to transfer large amounts of data to Azure Storage. It can be a cost-effective option if you are located in an area where uploading data over the network is expensive or not possible.
In Azure, when should Azure Site Recovery be used in a backup and recovery solution?
Azure Site Recovery should be used in a data backup and recovery solution for disaster recovery scenarios. This service helps ensure business continuity by keeping business apps and workloads running during outages, providing replication, failover, and recovery capabilities.
What does Azure Archive Storage provide?
Azure Archive Storage provides a low-cost, durable, and highly available secure cloud storage solution for rarely accessed data with flexible latency requirements.
Is Azure Backup integrated with other Azure services?
Yes. Azure Backup is tightly integrated with other services like Azure Policy, Azure Security Center, and Azure Storage to provide a secure and compliant solution.
Can Azure Backup support multiple restore versions?
Yes, Azure Backup retains recovery points created over time with configurable retention policies. This way, you can restore data from different points in time.
