You never test your backups to see if they can be read? You
assume that because there were no write errors that it can
necessarily be read back again????

I bet you *don't* do it like that!

Data integrity checks might (depending on the data and the
circumstance) require not just reading the data back again, but
actually comparing it to the file that it was copied from just
to be postive that every single bit is correct.

That's probably not necessary for most of us, but for bankers...
