VSX snapshot overhead on production

I am scheduled to apply a JHF to my gateways during a maintenance window tonight.  To minimize the window, I would like to run a snapshot before the window starts.  Does anyone know the resource utilization for a snapshot?  Will this have a huge impact on production traffic?

Re: VSX snapshot overhead on production

Dear David,

most used ressource if taking a snapshot will be the disksystem. If your gateway is not running near 100% on all CPUs, there will be no problem taking a snapshot. If you export your snapshot to an external system, there will be more CPU utilization because of some "tar" processes.

And have a look at the special handling for backup/restore of VSX-gateways sk100395. You have to take a snapshot and restore a snapshot on management and gateway from the same time. Except if you didn't changed the VSX-configuration.

best regards
