Figure 6‑2. Data Protection Service in vCloud Air (formerly known as vCloud Hybrid Service)
A virtual infrastructure administrator can configure data protection policies for virtual data centers, vApps,
and restore deleted vApps.
NOTE Logging in as an end user displays the vAPPs protected tab only.
When you enable data protection for a virtual data center, data protection is set by default to back up vApp
data every day between 6:00 and 10:00 UTC and retain the backups for 30 days. You can change the default
settings by editing the virtual data center policy. For example, you might want to edit the data protection
policy and change the backup window to avoid traffic latencies. When you enable data protection for a
virtual data center, you can customize the retention period for backups.
When a vApp gets backed up (either automatically by the system or when you back it up manually), the
Data Protection Service retains that backup as a restore point for 30 days by default. When the retention
period expires, the Data Protection Service automatically deletes and overwrites the oldest restore point.
To delete an entire backup, see “Delete a Backup Image,” on page 46 in this guide.
At the vApp level, you can disable backup and restore, set a customize retention period, or reset the data
protection policy so that all vApps inherit the policy from the virtual data center.
Details About Backup and Restore
When you change the disk configuration for a virtual machine, the Data Protection Service completes a full
backup of the virtual machine the next time the vApp is backed up.
If you add a virtual machine to a vApp and do not backup the updated vApp, and then restore the vApp in
place by using a out-of-date version of the backup, the Data Protection Service deletes the added virtual
machine.
A vApp is in Maintenance mode during backup and restore operations.
