Node stopping after image based backup has run

atinivelli

Good day
we have a 3 node vertica 8 cluster, running on sles11 VMs, on vSphere 5.5
It happens that during backup process one node stops. Restarting it always succeed.
We use Veeam, the leader in backup software for virtual environments. I guess that when the snapshot created for backup is removed, the brief stun the VM experiences, make sometime Vertica to stop.
We have plans to upgrade our hypervisor to version 6.x which has a new snapshot removal process that make the stun shorter, but i'd like to know if someone has a similare deployment of Vertica, and data protecion stragegy, and share our experiences.

Another topic related is: given that we don't have VSS on linux, and Vertica has not (if i'm wrong, correct me) a "backup mode" like Oracle, what is the best way to have application consisten backups of Vertica Database?

Thanks in advance
Alessandro

Wonder whether you evaluated the Vertica's backup tool for your needs?

yes, it would be nice to have an "application managed" backup, thank you for the tip (that should have been put in place from the guys they instelled Vertica )
As you can understand, the main advantage of using image-based backups, from the point of view of infrastructure administrators, is that we don't need to deal in deep with the procedures, tools, and syntax of every application/database/etc we have in our datacenter
