note that SQL database files generally can't be backed up safely while 
the SQL database server is active.   either take a 'dump' or whatever 
backup of the database, and backup that dump rather than the raw SQL 
files, or stop the SQL service before making the backup, then restart it 
afterwards.     Details vary per SQL server, of course.

what would work really well for your general backup requirements, 
ignoring the above issue, is BackupPC.  build an onsite backupPC server 
with a file system sufficiently large to hold all backups you want kept 
online (I generally do 2 weeks of incrementals), and setup BackupPC 
archiving to move copies of completed backups to an offsite repository 
for disaster recovery.
