x86/DOS system backup via rs232?

We used to back up to serial attached devices, such as tape drives or a serially attached hard drive, but I never did it to a different operating system, sorry. -----Original Message----- From: cctalk [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Jules Richardson Sent: Thursday, November 12, 2015 3:54 PM To: cctalk at classiccmp.org Subject: x86/DOS system backup via rs232? As per subject line, does anyone know of any util that will back up an x86 PC running some variant of DOS (MS, Compaq etc.) via rs232 to a remote system? (Linux preferable on the remote, but other options exist) I'm not finding anything via Google, but it seems like the sort of thing that some of the folks here may have done for their systems in the past. I'm thinking something that will do a sector-by-sector transfer from a given partition (maybe only in-use sectors, implying some minor intelligence on the remote end to covert into a raw image, but "send everything" mentality is better than nothing) - extra points for retrying bad sectors. cheers Jules --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
