Sono stato scritto script di backup per uso personale, installa come indicato in post da splattne :
----- Version: 2.0 - 2009-12-12 - SQL 2000 Compatible
----- Pham Kim Ngan (jbngan@gmail.com)
----- Usage:
-- Copy 7za.exe (http://www.7-zip.org/download.html - Command Line Version) to @CFG_BACKUP_PATH
-- Modify @CFG_BACKUP_PATH = <Backup Store Path> - no long filename/directory please
-- Modify @CFG_DAYS_DELETE = Days to keep backups
-- Enable 'xp_cmdshell' (SQL 2005/EXPRESS or higher)
