[SOLVED] Pacman backup local database with hook
At what stage is /var/lib/pacman/local updated when you install or remove a package using pacman?
Is it possible to, say, rsync or tar pacman's local database before installation/removal using
When = PreTransactionin a pacman hook?

Re: [SOLVED] Pacman backup local database with hook
Why would you want to back up the local database? There's nothing there that's not trivial to recover from your package cache or just a simple pacman command.

Honestly I don't know about pacman extensively, I was reading through the Arch wiki (1) (2) and thought it wouldn't be much effort to set up just in case.

I don't remove recent versions of package caches so I guess I don't need this. By simple pacman command are you referring to "pacman -Dk" or "pacman -Dkk"?

Re: [SOLVED] Pacman backup local database with hook
Ah, I suppose the installation reason can't be (trivially) recovered. I suppose there are use-cases for having a backup of the local database, but frankly they're far far more rare than might be inferred from reading those wiki pages.
I've been using arch linux for about a decade on several machines and I do all sorts of whacky experimenting and I've never had any reason to even consider backing up the local database. Perhaps that's just me though.
In any case, if you do want to do it as a pacman hook, you'd probably want it as a *post* transaction hook.

Re: [SOLVED] Pacman backup local database with hook
Thanks for the input, a post transaction hook works too. Marked as solved. :-)
