OPNsense Snapshots: The Feature You've Been Waiting For

Snapshots (aka boot environments) are now an official feature of OPNsense (as of v24.7.3). Thew new snapshot feature now allows you to take snapshots of your existing system, perform system upgrades, make configuration changes and rollback or switch between snapshots.
OPNsense snapshots are FreeBSD Boot Environments which depend on the ZFS file system for functionality. This video gives a quick tutorial and overview of what snapshots are (in relation to OPNsense) and how you can harness the power of them.

[@kukubau5690]

This functionality saved me around 10-15 hours. Great !

[@sheridans]

Thank you for taking the time to leave feedback, glad you found it useful 👍

[@bartje885]

Any way to use the CRON build-in scheduler to make a snapshot before auto update the firmware?

[@sheridans]

Sorry, no. They decided against auto feature as coupd cause people to run out of disk space if they didn't clean them up.

[@bartje885]

@@sheridans Well that makes perfectly sense, thanks. I will create a cron job for myself and a script that keeps the latest x snapshots. Thanks

[@sheridans]

@bartje885 don't give up hope, you never know what's around the corner 😀

[@Fede0068]

Well done. Great Job. Thank you.

[@sheridans]

Your kind feedback is much appreciated, thanks 😊 🙏

Welcome 🙏

[@nns353]

The best invention since sliced bread, Many thanks!!

[@robise.5886]

Amazing work! Thank you so much!

[@djdawso]

Very nicely done!!!

[@sheridans]

Thank you

[@Sherbibv]

Just wanted to ask how can we backup the snapshot externally? Like gdrive or nextcloud? Thanks for the functionality!

[@sheridans]

This is an awesomen idea, never came into my head. Since they're just zfs snapshots, they can be sync'd using zfs send/receive. Syncing the config is all that's needed really.

[@sixdonuts]

Very cool new feature.

[@sheridans]

It is!

[@over-there]

Thanks

[@sheridans]

Welcome, ty 😊

[@jamesyoung151]

Love the new feature! I already had to use it because I goofed earlier.

[@peetersbjorn]

but, if you do a system update, and it breaks the system (no access to ui or cli) then you can't use this to revert? (and you can't set the working config to R, because a firmware update might also reboot the system) ofcourse, as long as you have some parts working you can restore, and i do admit that this way is easier than the old way of getting the old xml back in there :)

[@sheridans]

I'm assuming only reason you wouldn't have cli access is remote?

[@doublecie]

Great tool.

[@sheridans]

I thought so :), thanks for your feedback!

[@jcnf76]

Great feature,if only native intel quickassist technology cards were supported out of the box
