VCB Snapshot kill's VM Network

[stony007_de]

Hey,

i have a problem with my 3.5 infrastructur! If the vcb backups snapshot starts and if the snapshot is deleting, the machines are loosing the network connection.

Does anybody got the same problem's or have some inforamtions, to fix this?

A couple things could be happening here. First a few questions.

What kind of storage is under the VM?

How large is the backup file?

My thought, if you have slower storage under the VM, and the backup is large, the snapshot could get quite large by the time the file copy portion of the backup finishes. This will result in a lengthy snapshot deletion process. Performance will be impacted during the snapshot deletion, especially if the storage is slow.

Hi!

i'm using an EVA6000 Storage with RDM's. The RDM Size is diffrend from VM to VM, From 50GB to 500GB!

Is there a possibility to tune up this snapshot process? it's very awfull, to lose some connections while the snapshot is merging!

VCB snapshot is similar just like you do a normal snapshot throgh VirtualCenter. Check manually when you create a snapshot on any VM and then remove that snapshot, would you see any network disconnection?

I suspect that vcb won't create any problem with network disconnection.

Otherwise put the vcbmounter output with -L 6 switch here...

if the backup is done and the snapshot is deleting, the status in the VC runs for 1% to complete, without errors.

But if the status is 90%, the vm timed-out for some seconds (5-30)!

My VCServer is an VM, could that be the reason for that mistake?
