Hi Venkatesh,

I assume your hypervisor is XenServer.

There is a global parameter called “snapshot.delta.max”, which allows us to 
take N incremental snapshots between two full snapshots.

It seems, the number of snapshots has crossed that value, so it has taken a 
full back-up again.
If you increase that value to a higher number, you can prevent it for long run 
but I don’t think you can prevent it completely.

Anshul/Sateesh, Correct me if I am wrong.


Thanks,
Nitin

Hi All,

Our CloudStack current environment is daily running recurring snapshots
enabled. Suddenly last night all VM's fully backed up ( not incremental
backups happen).



May I know the reason why all VM's are full backups. And also how to
prevent the issue.


Thanks,

Venkatesh
