Take care with what you backup; there is _no_ point in backing up any of the kernel's pseudo-filesystems including proc. Also, take care using mondo; the last two times I looked at it, the code was horribly trusting of information the user provided; the first time it could easily be provoked to SEGV errors. The second time, I contented myself with picking out some of the source code that I thought looked a but sus (I'm not much of a C programmer, and at my age I don't care to add it to my resume). People much more export than I (including Debian/Ubuntu developers) agreed with my appraisal. Worse, when I took it up with the author the first time, he denied flatly there was a problem, and claimed "It's not a backup tool, it's a disaster-recovery tool." It's a shame, because there's much to commend the basic idea. Take a look at DAR, it provides similar capability. It can be found at sf.net, and probably one or more of the extras repos. If there is a fan of mondo here who's a capable C programmer and who understands secure programming, I suggest you audit the code. Mondo needs it. -- Cheers John -- spambait 1aaaaaaa at coco.merseine.nu Z1aaaaaaa at coco.merseine.nu Tourist pics http://portgeographe.environmentaldisasters.cds.merseine.nu/ Please do not reply off-list
