This will make the dates associated with snapshots offset by how often cron is
run.
In other words, if you run above script daily you will have data from
2011.01.01 in the hex-2011.01.02 directory.
I do save the current date, do a LVM snapshot on the source, rsync --inplace
data over and do a local snapshot naming the folder using the saved date. This
way the date in the name of backup directory is exact to about a second.
