THIS IS A POST IN PRAISE OF SNAPSHOTS.

My PeerTube upgrade was a horror show: lost server connection during the upgrade and then PeerTube was automatically removed from my YunoHost server... the routine backup by YunoHost of PeerTube didn't restore... in short: bad, very bad outcome.

I hyperventilated for a few minutes and then... hit "Restore" on the VPS snapshot I had captured before the maintenance operation and... everything went back to normal.

Heart still beating a little fast but I am in AWE of the powers of SNAPSHOTS, ouf.

@elena Snapshots are amazing like that! Glad to hear that everything recovered nicely.

I second @teapot_ben’ tmux recommendation. I’m currently migrating a university’s learning management system to a new host & I’m doing it all via the command line in tmux.

Now, I’m not saying that I accidentally just hit Cmd-Q & closed the terminal in the middle of a database restore but if I *had*: no problem - I could just SSH back in, type “tmux attach” & be back where I left off - restore still running!

@drfyzziks @teapot_ben newbie question: I see in the YunoHost documentation that you can upgrade apps in terminal.

Can I simply run the command:

yunohost app upgrade peertube

in CLI or could I run into the same problem (server disconnect)? like is that what you mean when you say I should install tmux?

@elena @drfyzziks I'm not an expert in yunohost stuff, but if a server disconnect happened when using the web GUI to upgrade, then a similar problem could happen when you are using the CLI via SSH, with potentially bad results. The same is true when doing any remote sysadmin via SSH, not just yunohost upgrades.

I would definitely recommend installing tmux on the VPS, and starting a tmux session before doing any critical work.
