Azure Snapshots
Azure Snapshots are point-in-time, read-only copies of Azure managed disks (such as OS disks, data disks, or managed disks) used for backup, disaster recovery, and data migration scenarios. They capture the exact state of a disk at a specific moment, enabling users to restore disks to previous states or create new disks from snapshots. This feature is integral to Azure's storage and compute services, providing data protection and operational flexibility.
Developers should learn Azure Snapshots when working with Azure Virtual Machines or managed disks to implement backup strategies, perform safe testing by creating clones of production environments, or migrate data between regions. They are essential for disaster recovery plans, allowing quick restoration after data corruption or accidental deletions, and for cost-effective data archiving by storing snapshots in cheaper storage tiers like Azure Blob Storage.
