I'm not aware of any filesystem auditing system for Linux below the
network level.

Having deleted files recoverable would be a massive security problem.

Yep,  I bought an external USB drive (~80Gb) for something like $75.00.
Backing up my laptop takes about 15 minutes,  then periodically I attach
the USB drive to a real machine and back that up to a tape.

And the journal isn't very big,  data gets rolled over pretty quick.
