Reliable file system?

[Marcelo Magno T Sales <marcelo sales sefaz pe gov br>]

Hi, folks

I have an FC4 box in a location where there are electrical 
instabilities (i.e., frequent power failures). Often I get corrupted 
files after these failures.
Due to burocratic problems, I'm unable to get a reliable nobreak for 
this machine. Is there a more reliable file system (even if it's 
slower) to use in this situation?

Thanks,

Marcelo
