The ACF2 backup database files are VB or variable blocked. FTP loses the control characters during the FTP process. FTP transfer with mainframe files must be done with FB or fixed block. To maintain the correct formatting, we recommend that you use IBM's TERSE facility. Terse the file on the one mainframe, and transfer the files in BINARY, and then unterse them on the other mainframe. Use the same procedure as when sending files to CA to review.
