Alike’s Q-Hybrid jobs require that VSS (Volume Shadow Copy Service) is configured properly on your VMs/targets. Below is a small checklist for ensuring your VSS is in working order.
Required Windows Services
Check to ensure the following services are in an “Enabled” state. Your services can be managed by navigating to Start–>Administrative Tools–>Services.
- “Volume Shadow Copy” (Manual)
- “MS Software Shadow Copy Provider” (Manual)
- “COM+ Event System”
Check Your Available VSS Storage Space
You must be sure that you have sufficient ShadowStorage available for your VSS snapshots to function. On most Windows platforms, you can use the following command to resize your ShadowStorage as needed – please substitute your drives and sizes accordingly:
- vssadmin Resize ShadowStorage /For=[drive]: /On=[drive]: /MaxSize=[XX]GB
Check Your Writers
Running the following command will display all registered VSS Writers for your system. Note: Your writers should all return a “Stable” state.
vssadmin list writers
