This article currently only covers some classic DOS (and maybe Windows) versions from the floppy disk era.<br /> <br /> A version of Norton Backup was rebranded as '''Microsoft Backup''', and included with [[MS-DOS]] 6.x. The executable file is MSBACKUP.EXE.<br /> <br /> == Format details ==<br /> When backing up to a set of floppy disks, one file is written to each disk. Files use extensions '''.001''', '''.002''', etc. The base filename is something unreadable like &quot;DD41001C&quot; or &quot;GG41217A&quot;, presumably derived from the date, and other things.<br /> <br /> == Identification ==<br /> More research may be needed. Known files start with byte {{magic|0x00}}, then an ASCII string that starts &quot;{{magic|NORTON&amp;nbsp;Ver}}&quot;.<br /> <br /> == Software ==<br /> * [https://winworldpc.com/product/norton-backup/11 Norton Backup], at WinWorld<br /> <br /> == Sample files ==<br /> * {{CdTextfiles|cream09/program/vbxgalor.zip|vbxgalor.zip}} → CC50719A.001<br /> <br /> [[Category:MS-DOS]]<br /> [[Category:Multi-file formats]]</div>
