is running rsync after filesystem crash enough?

view story

http://serverfault.com – On my Debian Squeeze server, a filesystem crashed badly. I ran fsck.ext4 on it and it corrected many things. Now everything seems to be fine. Additionally, ran an rsync from a recent backup to the failed filesystem. My question: Now that rsync has run, can I safely assume that the file contents on my server are identical to those in the backup? Or would it be advisable to just recreate the filesystem and re-copy all data from the backup? I'd rather not do this, due to the high traffic (it's a large filesystem ...) Any help is greatly appreciated =) (HowTos)
