I think you get that message just because you've given the -u option.
zip issues this warning if there's no .zip file to update, yet (when
you run the command for the first time).

What's a little strange is the name "/home/acct.zip"... Are you
actually passing some file name (the parameter $1) to the script?
In case not the zip command would collapse to

  zip -ruv $DATADIR >> ...

which might explain why it's trying to access /home/acct.zip :)
