Hi Michael, > An rsync server? I need help ... there is not enough time If you ask me, rsync works well and is safer when you can do it over ssh, but that sort of leads to the question whether you have a SSH server for DOS. Nice clients include ssh2dos. > strict programming API I can use temp files as backing storage Note that DOS is not multi-tasked so that will also have some issues.

I guess some compilers or macros could add null pointer checks for you or could even check at compile time whether there is a risk to use un-set pointers at all.

I started looking at the rsync client - getting past the compiler and build system dependencies is a major chore. There are funny things like "typedef int int" in there that Watcom doesn't like; unraveling the macro pre-processor expansions to find the culprits takes time. I suspect that the change to use mTCP instead of Watcom will be far easier, but it takes a while to get to that point. Depending on the rest of the client, the speed difference may not be that great - that remains to be seen. (If it is mostly tied up in disk I/O or something cpu intensive then the TCP part might not make that much of a difference.) An rsync server? I need help ... there is not enough time in the world. (To that end I've been updating the Wiki documentation at the Google project hosting site - I've added a lot of design documentation lately.) On a slightly related topic, I've been thinking about what to do on the smaller machines to increase the amount of working storage. With a strict programming API I can use temp files as backing storage, kind of like implementing bank switched memory but backed by hard disk storage instead. Pretty slow, but better than not having any extra memory storage. One thing that frustrates me is that there is no way to make a 'bad' pointer on an 8088.

It's indeed dated from 2003, though, so I guess it could've been in FD

Re: [Freedos-user] dos backups in the 21st century?
Hi Karen, Try to find a copy of Powerquest Drive Image or Powerquest Partition Magic (which also has the function to backup drives). I have used Powerquest Drive Image for years. Paragon Software have DOS versions of their software: Hard Disk Manager, Partition Manager, Disk Backup - all have the ability to clone drives or backup a whole drive to a backup file that you can use to restore the drive. Media Tools Unlimited is also a DOS tool with the option to clone failing drives. http://www.atl-datarecovery.com/data-recovery-products/media-tools-professional/ cheers Bob Dyster -Original Message- From: Karen Lewellen [mailto:klewel...@shellworld.net] Sent: 17 August 2011 14:13 To: freedos-user@lists.sourceforge.net Subject: Re: [Freedos-user] dos backups in the 21st century?

Disk images are just that - you would have to restore them 1:1 to a partition or in the worst case disk of the same size, leaving the rest unused and not having easy access to the files inside the image. Also, the images tend to be larger than 2 or 4 gb, which limits the possibilities for storing them on old filesystems such as pre-NTFS USB sticks and so on. While 3 GB are not much data, 20 GB already are annoying for USB 2.0 Also, restoring disk or partition images in a way that they still boot might also take extra work, see above.

If you use dos alone and purely on your machine, but nevertheless have some *nix server access you can use rsync client for dos: http://www.2net.co.uk/rsync.html If it is the case, than probably this will be the best solution, as rsync is one of the most widely used tools for backups.

They (e.g. Dell) already advertize 3 TB disks for like $119US or whatever. 3 GB should be easy (in theory). I don't really understand the question (and of course am the worst person to ask). Are you trying to backup the entire DOS partition (3 GB) to network or just to external drive or all of the above or ... ? Symantec (Norton) Ghost allegedly used to have a DOS version. Not sure if the latest still has it, even in an "/old/" subdir. That always sounded like the best way to do it, and CWS always seems to swear by it. Otherwise you're probably going to be told, "Boot a Linux live CD, use their tools". Even dd could probably be used, but I wouldn't recommend that except in a pinch. Personally, I'd probably just burn the files to DVD-RW from within a "modern" OS, esp. if you "only" need to backup 3 GB.

Data: * 7zip (if it allows backup output to consist of split files) * MKISOFS (store data as ISO in split files) * XCOPY /S Partition/Harddisk: * some complete partitioning program, SAVEPART I guess?
