comment Back up script causing issues
Can you add some details to your post, like the size of the sql file, the size of the gzipped file, a df and free output at the various stages. You don't need to copy the gz around in the fs, just add it to the tar from where it is. You also can use gzip -9 or even better use bzip2 or xz.

Use double quotes for the ssh command and then single quotes for the column and for the DBHost. You could also replace the backticks by a $() construct.
