Yes, there is. Write a shell script that contains all the command lines
you want to run and use cron to call it periodically.
As for the dated filenames, it's easy:
#!/bin/sh
outfilename="backup-"$(date '+%y-%m-%d-%H%M')".tar.bz2"
echo "Saving files into: ${outfilename}"
tar cvf - path/to/dir/1 path/to/dir/2 | \
bzip2 -9c -> "${outfilename}"
This should be almost all you need.
