Backup via customer center and instance snapshot via Horizon

Hello,

i try to find a good solution for the scenario that I need to revert changes (after application updates or so) I did to a virtual machine in the Public cloud.

In OVH customer center I can create a backup of my instance - but this takes to long for me, 2.5 hours in the moment.
I'm not sure if I could start applying my changes to the system right after I hit the instance backup button. Does anyone know if I have to wait until backup is completed?

In Horizon I can create instance snapshots which I can later find as image in Horizon > Images. Would this be a faster solution, create snapshot of my instance and start with applying critical changes to my VM right after hitting the snapshot button?

Any feedback is appreciated!
Thanks and bye, Peter

the snap is the right solution to made a fast “photo” of the vm before to apply some updates.
Bye,
