It is a mod of vbulletin.
why u need modfor that simple work if you have ssh access then its so easy to take backup if not use mysqldumper using this i can take big dump backup
mysqldump -u YOUR_Username -pYOUR_Password YOUR_Databasename | gzip -9 > /home/YOUR_Folder/storage/YOUR_Databasename.sql.gz
So it does it auto everynight.
mysqldumper is an great program if u set an CORN job for that work it will take backup based on CORN job and it also can upload into your ftp server also auto its have sql splitter also :D
