Oh well then in your case it might make sense. However, don't underestimate how much time can be lost during 'saving' a borked installation or something like that. As mentioned before, from my experience I'm quicker to reinstall OS and software than fixing stuff.
For example, on this node I purposely put the blockchain directory on a secondary drive, so I can kind of play around with the OS, possibly try LND, go back to C-Lightning and all that, simply by wiping and reinstalling what I like to try next, without ever risking to lose the blockchain really, quite convenient. And to be fair, if you do need to copy a few hundred gigs, it can take a few hours, but you don't have to sit and look at it. Start that rsync and let it run..
