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?

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.

Hi, we have cluster of VSX and it has 3 VS. Do we need to take snapshot only from VS0 OR all 3 VS. Also got the following commands to take snapshot and restore, Can you please confirm the commands?

vsx from clish
add snapshot <Name of Snapshot> desc "<Description of Snapshot>"
set snapshot revert<SPACE><TAB>

Those commands are correct and you are using them on clish so it would be VS0.

You can also use this command for the status of the snapshot, "show snapshots"

If your just installing a Jumbo on the VSX appliance, then you just need to do a snapshot on each of the nodes, if you want to do the manager, feel free, but I personal don't as the version is not actually changing.

Snapshots timing varies, but I would expect it to too long ie. say 15 mins.
