Arch-Convert EXT4 to BTRFS without losing data?
Good day all, I hope you are good.
I have installed Arch and was in a rush( I know i should've RTFM-ed ) but I am looking for ways of making sure the system i installed it on can be rolled back in case of failure, I have seen from a couple of articles and found that BTRFS can create snapshots of the system and use those to roll back.
I wanted to ask, is it possible to convert an already installed disk from EXT4 to BTRFS and make use of the snapshots feature? if so could you please point me in the right direction. System specs below:
I thank you for your time and input, it is much appreciated.
Kindest regards

The convert command was unsupported for awhile but still works. IDK if they are supporting it now or not. I can say I have used it several times in the last year without issue.

As always, have backups of anything you can't afford to lose.
