Server :: Backup One Liner Find Xargs CP

I will eventually script this but wanted to know where I screwed up when trying to get this oneliner to work. In a nutshell, I want to created a backup directory, find any files that have changed in the last 48hrs and them copy them to the newly made backup directory.

PHP Code:
date=$(date +%m%d%Y)mkdir -p /home/test_dir/backup$date;find . -mtime 1|xargs -0 cp -r -t /home/test_dir/backup$date

When I do this I get:
PHP Code:
a bunch of junk !#$#$$#! File name too long

I also tried:
PHP Code:
date=$(date +%m%d%Y)mkdir -p /home/test_dir/backup$date;find 
. -mtime 1|xargs -0 cp -r {} /home/test_dir/backup$date
