For starters, .tar.gz is the preferred way to name gzip-compressed TAR 
archives.

What do you mean by "[this gets the dir name]"?

As ever with scripts of this sort, it's advisable to quote variables and 
placeholders (like the {}) so that special characters don't mess up the 
interpretation of the command.

Be specific about what "isn't working." Are ensuring that you're 
executing the command in the proper directory? Are you running this as 
root or another user? Are you getting mail from cron describing a 
failure?

One generic hint is to put only a simple command name in your crontab 
and do all the real work in that script. Set the PATH and MAILTO 
variables, too.
