SwapDrive operates two online backup services: @Backup (which we covered last year) and the newer SwapDrive Backup. The priciest online backup service in this roundup, SwapDrive Backup performs basic backup functions via browser- and client-based applications. Like the client-based version, the drag-and-drop browser interface permits file and folder operations, but you must relax your browser's ActiveX security settings. Only the client version permits scheduled and incremental backups. But the PC client invokes the Web interface to perform a restore operation. Users can share data by sending file links using WhaleMail, an online file-transfer service. Additionally, you can share folders with other SwapDrive Backup users and configure them with read/write privileges. The client lacks an elapsed backup time indicator. SwapDrive Backup uses WinZip to compress files.
