Subject RE: Customer Backup with CS 4.7 and VMWare
Date Wed, 14 Feb 2018 19:39:21 GMT
Hi Sebastien,

Your points are noted; The plan is to make backups a first class citizen, so their lifecycle
is somewhat independent of the VM of that they are based on.
Users will be able to choose between policies (as defined by the vendor/Cloud Operator), ad-hoc
backups and scheduled backups (the same as snapshots).
Users will have to opt-in to any backup regime, so they are free to use client backup agents
if they chose, ultimate it would be good to include support for those, but it is considerably
more complicated, so out of scope for the moment.

I hope this answers your thoughts.

Thank you Paul, its a good proposal.

This is a really piece to get a global solution. I think that it should be treated like load
balancer, where Cloudstack offers a simple, but useful solution, and Cloudstack allows to
integrate dedicated solutions like F5.
In fact, Cloudstack just offers a global solution, snapshots. This is a very basic solution,
but is a solution.

Would be great that Cloustack allow integration with solutions like Veeam (p.ex). The connector
(configured by cloud administrators) would allow users to include each vm, and manage the
recover from the cloudstack console (something similar to the current VM snapshot management).
And still more difficult: what happen with deleted VMs? How to interact with ... whatever
... to recover a virtual machine that just does not exists on CS.

But meanwhile, general solutions (like veeam) does not allow to delegate on users their own
We have some clients that uses backup agents on their virtual machines using their own backup
services (like EMC Networker).

@Simon Weller: Ceph, also sounds great...

What else?
