Currently one of the SharePoint 2010 site collection Content Database size grown to 200 GB. We need help to reduce this database size where We can use MS recommended standard Import-Export, Backup-Restore methodology for subsites which can be moved under new site collection.What are the other options we will have in case Import-Export, Backup-Restore methodology is not feasible?Since currently we are facing some issues with Import-Export, Backup-Restore methodology. Is it reliable while working on Production with minimum downtime.Do you recommend any 3rd party tool to resolve this considering application customization, huge data, big file size etc. Regards, Nitin Patilnitin patil
