Hi All,

We are using CS 4.7.1 with VMWare Hypervisor and advanced networking in a 
private cloud environment. Currently, most of our (internal) customers hosting 
internal services within this environment are using volume snapshots to 
facilitate backups of their virtual machines. Besides the obvious downsides of 
this approach (consistent snapshots of multiple volumes, …) we encounter 
serious problems using this features. In ~10% of the cases, snapshots get stuck 
in the BackingUp state, which sometimes causes the whole snapshot queue to 
stale. In some other cases, recurring snapshots are correctly configured, but 
CS does not try even try to create this snapshot, there is no entry in the 
database.

In summary, we are currently evaluating different options, hence my questions 
here:


  *   Are we the only ones encountering that massive problems with volume 
snapshots? Or is this a known problem? Anything we could look at or a hint 
where we could start troubleshooting?
  *   How are you actually providing backup services to the customer? Are there 
other solutions or products that integrate with CS?

When using another option than the volume snapshots in CS, the most important 
factor would be to keep the ability for the customer to configure everything in 
self-service.

Thanks and regards
Daniel
