To design your protection deployment for virtual machines, classify VMs according to the recovery point objectives (RPOs) for different types of VMs.
Tier 1
Tier 1 VMs are the most critical VMs:
-
First priority for recovery
-
Multiple recovery points per day
-
1 TB or more in size with multiple disks
-
High transaction and data change rates
-
Dedicated resources
Note
Recommended Protection Method: Use IntelliSnap backups for Tier 1 VMs.
Tier 2
-
Second priority for recovery
-
One or two recovery points per day
-
Moderate to low transaction rates
-
200-500 GB in size with multiple disks
Note
Recommended Protection Method: Whenever possible, use traditional streaming VADP backups. If necessary, schedule daily or twice daily IntelliSnap snapshots to support fast recovery. For special cases use in guest agents.
Tier 3
-
Lowest priority for recovery
-
One recovery point per day
-
Low transaction rates
-
Fairly static data
Note
Recommended Protection Method: Use traditional streaming VADP backups with no snapshots.
