Will this update get me over 30 fps, or break my ability to boot into a GUI?

There's only one way to find out ;)

For me, it is wanting to implement something myself takes time not because the said thing is complicated but because of the inertia. I have been sitting on a 3-2-1 sync + backup solution for months now.

I do have hope that this delay goes down as I keep implementing things.

libimobiledevice[1]'s idevicebackup2 can backup iDevices the same way iTunes does.

Yes there are options but no way I can trust this with my phone data. :) I guess oone option would be cut the network, then backup.After that I nuke the linux? and restore from backup each time.

It's encrypted/decrypted on the phone if you enable encryption (like iTunes).

If this is a concern, you could use a VM without network access to make the backup
