Zorluk: KolayDesign Azure Backup Solutions

An organization needs to set up a backup strategy for their Azure Virtual Machines hosting development and testing workloads. The design must meet the following requirements:
- Minimize storage costs for the backup data.
- Retain daily backups for 30 days.
- Provide the fastest possible restore speed for the last 5 days of backups.

Which of the following configurations should you include in the backup design? (Select TWO).

  1. A Recovery Services vault configured with Locally Redundant Storage (LRS)Cevap
  2. A backup policy with the instant restore retention range set to 5 daysCevap
  3. C
    A backup policy with the instant restore retention range set to 30 days
  4. D
    A Recovery Services vault configured with Locally Redundant Storage (LRS) to protect against a regional outage

Cevap

To meet the requirements of minimizing costs and allowing rapid restore for the last 5 days, you should configure the Recovery Services vault with Locally Redundant Storage (LRS) and set the instant restore retention range to 5 days in the backup policy.
For non-production development environments, minimizing costs is achieved by using Locally Redundant Storage (LRS). Rapid restores are achieved by keeping snapshots on local disk using the instant restore feature, which is limited to a maximum retention of 5 days.

Adım Adım Çözüm

1
Select the backup storage redundancy option that minimizes cost.
Choose Locally Redundant Storage (LRS) because it is the cheapest storage replication option for the Recovery Services vault.
LRS keeps three copies of the data within a single datacenter, which is sufficient for non-production environments and reduces costs compared to zone-redundant or geo-redundant storage.
2
Determine the configuration to achieve the fastest restore speed for the most recent 5 days of backups.
Configure the backup policy's instant restore retention to 5 days.
This retains the backup snapshots on the local disk tier for 5 days, allowing fast, disk-level restore operations instead of copying data from the vault.
3
Verify retention limitations for daily recovery points.
Keep the remaining 25 days of recovery points in the vault tier by setting the total retention to 30 days.
Instant restore snapshots cannot be kept for 30 days due to the 5-day limit, so the rest of the 30-day period must use vault-tier storage.
