There's nothing "religious" about it, at least not since Elizabeth
Zwicky published her study of the reliability and capabilities of
various backup programs.....
Elizabeth Zwicky, "Torture-testing Backup and Archive Programs:
Things You Ought to Know But Probably Would Rather Not," LISA V
proceedings, San Diego, 1991, pp. 181-185.
Unfortunately it is not available from Usenix/SAGE online....
but unofficial archive copies are here:

As for Linux brain damage, well, that's not very "religious" either.
Dump is broken for mounted filesystems and Linux 2.4 kernels -- end of
story. Unmount your filesystems before backing them up, and go single
user and cross your fingers to backup your root filesystems!
