I have a 20GB partition that I need to image and create a recovery disc. No matter what compression I use, the resulting image file is more than 4.5GB (smallest I could get it was about 7.5). When I try to create an ISO for this image, it fails. The partition is as small as I can get it for the purpose I have in mind.
Are there are any work-arounds for the 4.5GB limit on creating ISO files, or is there another way to accomplish the goal of creating a mostly automated recovery DVD for non-technical users? I was really hoping that Clonezilla would be capable of this, but I've tried different things and I've learned virtually nothing.
Thanks,
Nathan

Sorry, no. It's a tough issue for this kind of piping programs to deal with multiple CDs/DVDs when restoring.
Maybe you can use double layer DVD? Or a USB flash drive?

Steven - I may be grossly misinterpreting the documentation, but I'm actually trying to use a dual-layer burner & media. My understanding of the documentation is that mkisofs only allows up to 4.5GB ISO files (which would make sense for fitting it to a standard, single-layer DVD).
I haven't tried the USB drive yet because I have been doing ISO files plus USB or just ISO alone, and every time I do, I get errors. I'll check out the USB-only option and see what I can come up with. Do you know that the USB method works for image files greater than 8GB in size?
Thanks,

Steven - I tried doing just the ZIP for flash drives today, and the file creation errored out at just over 4GB, out of an estimated 10+GB that was projected. Not sure what the issue was, though - it just reported the failure was unrecoverable. The resulting file was corrupted. There was plenty of space available on the target drive (upwards of 90GB).

BTW, "My understanding of the documentation is that mkisofs only allows up to 4.5GB ISO files " -> In Clonezilla, genisoimage is used to create the iso file.

What's the file system on your flash drive? If it's FAT, there is a limit for single file size ~ 2 GB.
Try to use NTFS.
