SQL server and Sybase backup server
SQL Server performs Sybase backups and restores by sending Sybase DUMP and LOAD directives to Sybase backup server. Sybase backup server is an Open Server application that prevents backup and restore tasks from interfering with user processes. SQL Server and Sybase backup server are installed and configured with Sybase's regular installation facilities.
When either a Sybase DUMP or LOAD command is processed, SQL Server sends Sybase backup server the directives to dump or load the specified database or transaction log. These directives indicate which set of archive devices to use for the dump image. Sybase backup server then handles all data transfer for the operation.
