You always get back whats on your side of the channel. For a 1M sat channel for example. If my side has 100k sats and the other side 900k sats. I get back 100k the other guy gets 900k. Works well
If someone got a hold of a backup of your channel and tried to restore it while you’re offline, they could try and get your sats by closing the channel. But that’s why you setup watchtowers with your peers to protect you while you’re offline. (keep in mind thats pretty unlikely)
I spent quite some time reading about lightning. It is a fabulous system. Ad-hoc establishment of cryptographically secured payment routes is non-trivial, to say the least. I can imagine that the network will grow 1000x over the following years (and so will channel opening costs). So for people who have an interest in working on censorship-free and open payment rails for everybody who wants to use it: now is a good time to start (I know we can't have 8 bn lightning channels - not worried about that).
