LRS is a low-cost option for protecting your data from local hardware failures. All copies of the data exist within the same region. Locally redundant storage (LRS) replicates your data three times (it creates three copies of your data) in a storage scale unit in a datacenter.Item Level Restore (ILR): Restoring individual files or folders inside the VM from the recovery pointĪvailability (Replication types): Azure Backup offers three types of replication to keep your storage/data highly available: This replaces the OS disk and the data disk(s) of the source VM.Īlternate-Location Recovery (ALR): A recovery done from the recovery point to a server other than the original server where the backups were taken. Original Location Recovery (OLR): A recovery done from the restore point to the source Azure VM from where the backups were taken, replacing it with the state stored in the recovery point. In phase 2, the snapshot is transferred and stored in the vault managed by the Azure Backup service.So restore from the snapshot tier is also referred as Instant Restore. Snapshot tier restores are faster (than restore from vault) because they eliminate the wait time for snapshots to copy to the vault before triggering the restore. In phase 1, the snapshot taken is stored along with the disk. vault): Azure VM backup happens in two phases: Recovery Point (also known as Restore Point): A recovery point is a copy of the original data that's being backed up. We'll discuss the various scenarios they support. This article describes how the Azure Backup service restores Azure virtual machines (VMs).
