VADP backup takes a long time when manually created snapshot already exist

Hi,

my customer is using Commvault for VM image backup. We've noticed that when snapshot exist on VM we have performance issue. Backup of VM which normally takes 5 minutes  could takes more than 5 hours. Sometimes it can takes 24 h and failed. 

When we have changed transport mode from SAN/Hot Add to NDB then backup takes 10 minutes. 

Is that normal when other manually created snapshot already exist? Is it limitation of VADP API?  Is there any recommendation and best practices for VADP backup?

Regards,

Lukasz

As your post needs moving to the area for vSphere backups, I have reported it to the moderators.
