• Configure/Schedule a Backup Job within SQL Manager on a nightly basis.  
• Then it would be up to System Administrator to maintain and cycle through the backups created.  
• For example:  you might go through and just keep a Rolling weeks worth of backups available, each day you could go and purge off the oldest backup (which would be approx 1 week old). 
• In addition to the rolling weeks worth of backup we would also suggest picking maybe the 1st of every month and keep those backups on a permanent basis or a Rolling Year or Rolling 6 months.  This could come in handy down the road if some major situation occurs or some clients even refer back to those monthly backups and use them for accounting evaluations.
