Managing VPGs : Editing a VPG
  
Editing a VPG
You can edit a VPG definition, including adding virtual machines to the VPG, as described in Adding Virtual Machines to a VPG, deleting virtual machines from the VPG, or changing the information about how virtual machines are recovered.
Note: You cannot edit the VPG while a backup job is running.
After modifying the VPG, the definition is updated.
While the VPG definition is being updated, you cannot perform any operations on the VPG, such as adding a checkpoint, editing the VPG properties, or failing the VPG.
After the definition is updated, the VPG is synchronized with the recovery site.
To modify a VPG:
1. In the VPGs tab in the Zerto User Interface, select the VPG to be edited and click MORE > Edit VPG. You can also select the VPG, display the VPG details, and click EDIT VPG.
The Edit VPG wizard is displayed, enabling editing the VPG, including adding and removing virtual machines from the VPG.
Note: If the VPG was previously viewed, and the tab for this VPG is still displayed, you can access the details by selecting the tab.
2. Make any required changes to the VPG definition, as described in “Protecting Virtual Machines from a vCenter Server”, on page 45 and in “Protecting Virtual Machines to and From vCloud Director”, on page 120.
You can jump directly to a step to make a change in that step, for example, the REPLICATION step or the RECOVERY step, by clicking the step.
Steps that have been completed are marked with a check.
Note: If the Journal Size Hard Limit or Journal Size Warning Threshold in the advanced journal settings for the VPG SLA settings, or the default values are changed, the changed values are applied only to new virtual machines added to the VPG, and not to existing virtual machines.
3. Click DONE.
The VPG is updated and then synchronized with the recovery site, if required, for example when the host was changed.
 
NOTE:
Changing a recovery Org vDC when recovering to vCD, results in an initial synchronization, resulting in all the checkpoints being deleted.

Modifying the Journal Size Hard Limit
If the journal size hard limit is reduced, and if the current size is greater than the newly defined size, the journal remains at the current size. When the amount of the journal used falls below the hard limit value it will not grow greater than the new hard limit. Unused journal volumes from the added volumes are marked for removal and removed after the time equivalent to three times the amount specified for the journal history, or twenty-four hours, whichever is more.
Note: If the Journal Size Hard Limit or Journal Size Warning Threshold in the VPG SLA settings are changed, the changed values are not applied to existing virtual machines but only to new virtual machines added to the VPG.
 
Modifying the Retention Period for Offsite Backups
If the retention period is shortened, the number of backup jobs older than the new retention period are deleted from the repository.
 
Modifying VPG Recovery Volume
If you change the recovery volumes in the Storage step from thin-provisioned to thick-provisioned or vice versa the volume goes through initial synchronization.
