Files in a jail are in fact just files on the host, so you could 
certainly do that. But as in many things (and especially when 
talking about backups), "best" is framed by local conditions, 
practices and requirements. There's nothing much special about 
backing up jail files though, so do what you normally do.

There are by default some constraints on jailed processes using 
devices. This may or may not affect trying to run backup processes 
from inside the jail. Backups running in the host environment have 
no such constraints.

Personally, I like to configure all jails on a standalone /jails 
partition so that I can easily take a snapshot from the host and run 
a backup against that.
