为什么 Azure VM 还原操作会导致备份操作
Why Azure VM Restore operation leads to Backup operation
我使用 Recovery Service Vault 来恢复 VM。选择 "Restore point" 并激活 "Replace existing" 操作后，我转到 "View all jobs" 页面，可以看到在 "Restore" 操作后立即启动了 "Backup" 操作。我找不到任何关于为什么会这样的文档。出于什么原因启动此备份操作？
当您从还原点替换现有磁盘时，这些可能是您正在寻找的：
If you restored a VM to the same resource group with the same name as
the originally backed-up VM, backup continues on the VM post restore.
If you restored the VM to a different resource group or you specified
a different name for the restored VM, the VM is treated as if it's a
new VM. You need to set up backup for the restored VM.
作为替换磁盘功能的一部分，我们在替换磁盘之前进行了按需备份，以便还原操作中的任何错误，我们都可以回滚操作并保持源 VM 干净。
根据[https://docs.microsoft.com/en-us/azure/backup/backup-azure-arm-restore-vms#replace-existing-disks-from-a-restore-point]，
"During replace existing disk(s) operations, as a precautionary measure, we backup the data before initiating the replace disks operations."
