We want to take this opportunity and alert our customers that we have identified an issue when using the built-in Symantec Endpoint Protection Manager utility "Database Back Up and Restore" with a large database size that results in a zip file greater than 4 GBs.
Development has determined that this is not a product issue and is currently working as designed. The backup and restore utility does not have a size limitation. The built-in utility is able to read and restore its own backups. The issue is that third party zip utilities are not able to read and understand our backups when the zip file size is greater than 4 GBs. The backup files are actually no longer a standard zip file and can only be read by our built-in utility during a restore. Development is researching a possible product design change in a future release to avoid this confusion.
For information about how to backup the database using Microsoft SQL 2005, read the following document: Backing up a Microsoft SQL 2005 database with the Database Maintenance Plan wizard.
