A backup was created using the stsadm.exe command from WSS 2.0. Recovery Manager for Sharepoint cannot process this backup.
The console_s.log shows an error like the following:
3/10/2008 3:45:30 PM 2200:1 [Warning] Verifying backup file \<server_nmae>E$<folder_name>SharePointBackup03082007.dat failed with error message: The media family on device \<server_nmae>E$<folder_name>SharePointBackup03082007.dat is incorrectly formed. SQL Server cannot process this media family.
RESTORE FILELIST is terminating abnormally.
Recovery Manager for SharePoint only supports full content data base backups and not site collection level backups. The stsadm.exe command from WSS 2. 0 cannot create full content database backups but the stsadm.exe command included with WSS 3.0 can.
A backup must be created using one of the supported methods. Recovery Manager for SharePoint supports native SQL Server (including LiteSpeed-enhanced) backups of SharePoint content databases. A native database backup is the one made using the MS SQL Virtual Device Interface API and stored in the SQL MTF format.
Examples of tools producing native SQL Server backups in the SharePoint world are SPSBackup.exe, SharePoint 2007 Backup and Restore Tool (Central Administration and stsadm.exe), SQL Server Management Studio, 3rd-party SharePoint backup solution based on SQL database backups.
Non-native backups of SharePoint content, which use their own backup format, are not supported by Recovery Manager for SharePoint. Examples are site collection level backups made with stsadm.exe, 3rd-party backup solutions using proprietary backup formats.
