VRA0039 – The journal for VM in VPG has reached its configured hard limit

Viewed 1160 times


When creating a VPG, there's a value that can be set to limit the journal maximum size (the hard limit).
The default value is 150Gb. When the journal size hard limit is reached, then the old checkpoints will be promoted to the recovery disks and new checkpoints will be written.
This will cause the journal not to be populated with the number of checkpoints it should have (according to the SLA set by you).

For example: 
Journal is set for 4 hours.
Journal size limit is set to 50GB.
After 30 minutes the hard limit is reached and old checkpoints are being applied to the recovery disks meaning the journal contain 30 minutes worth of checkpoints.

An alert will be displayed in the Zerto GUI, it will be in the following template.
The {journal} journal for VM {vm_name} in VPG {vpg_name} has reached its configured limit of {x}. Older checkpoints might be removed and the journal history might be reduced to make space for new data.


To avoid this scenario you can either increase the journal size hard limit (or set the journal size to 'Unlimited') or follow our journal sizing tool to get an estimation of the journal size expected for your VMs and update the settings accordingly:

To update the journal size hard limit value, please follow our admin guide (starting at step 13):
