Zorluk: OrtaDesign Azure Backup Solutions

An organization runs a critical transaction system on an Azure Virtual Machine. The virtual machine is configured with Premium SSD v2 managed disks. You need to establish a backup policy using Azure Backup that satisfies the following operational constraints:

* Retain daily recovery points for a total duration of 60 days.
* Guarantee near-instant recovery times for any file restoration from backups that are up to 6 days old.
* Recoveries from points older than 6 days may be performed using standard vault retrieval times.

Which backup policy configuration should you recommend?

  1. An Enhanced backup policy with the snapshot retention (instant restore) set to 6 days and the vault retention set to 60 days.Cevap
  2. B
    A Standard backup policy with the snapshot retention (instant restore) set to 6 days and the vault retention set to 60 days.
  3. C
    A Standard backup policy with the snapshot retention (instant restore) set to 5 days and the vault retention set to 60 days.
  4. D
    An Enhanced backup policy with the snapshot retention (instant restore) set to 5 days and the vault retention set to 60 days.

Cevap

An Enhanced backup policy with the snapshot retention (instant restore) set to 6 days and the vault retention set to 60 days.
The Enhanced backup policy is required to support Premium SSD v2 disks. Furthermore, the Enhanced policy allows the snapshot retention (instant restore) to be configured up to 30 days, which satisfies the requirement for a 6-day rapid restoration window. The vault retention can then keep the recovery points for the remaining 60 days.

Adım Adım Çözüm

1
Analyze disk compatibility requirements for the Azure Virtual Machine.
The virtual machine uses Premium SSD v2 managed disks, which are only supported by the Enhanced backup policy tier in Azure Backup.
Azure Backup Standard policies only support Standard HDD, Standard SSD, and Premium SSD (v1) disks. Premium SSD v2 and Ultra Disks require the Enhanced policy tier.
2
Evaluate the instant restore (snapshot retention) requirements.
The requirement is to provide near-instant restores from backups up to 6 days old. This requires setting the snapshot retention to at least 6 days.
Standard backup policies limit instant restore snapshot retention to a maximum of 5 days. The Enhanced backup policy allows snapshot retention to be configured up to 30 days.
3
Combine the disk support and snapshot retention requirements to select the correct policy configuration.
Select an Enhanced backup policy with snapshot retention set to 6 days and vault retention set to 60 days.
This satisfies the disk type constraint, enables the 6-day instant recovery window, and maintains the total backup history for the required 60 days.
