PSA: The Importance of Backup, Golden Parachutes, and Don't Panic

So the big news on my F-List today regards the announcement that SUP (LJ's owner) has laid off a significant portion of its US support workforce. I gather that the general concern is for a decrease in support for the platform, which I think is valid.

I thought I'd make a post to gather up some links for my own future reference and that might be of use to some of you.

( Anyway...what to do? )

ETA: A post on no_lj_ads regarding the layoffs

ETA 2: Backing up your LJ (Windows)
