Sorry, I guess they must be having some problem with the server. Try: http://freshmeat.net/projects/dar/?topic_id=19%2C137%2C42%2C41%2C147
Ah, that one works - although with a comercial from M$ on the side ;-) Ok, I'm downloading it, I'll try it.
About the problem with loosing all data on multi-volume compressed archives with tar: The dar docs state that it will only loose the "corrupted file" unless the corruption occurs in the first few header bytes of each slice, or the last slice which is the "catalog". So all you really need to do is make a double backup of the last disk. It is quite reliable.
Sounds nice. One thing I'm trying is making compressed cdroms with zisofs. This cdroms are readable transparently by the kernel, so that you can read any file instantly with any software. Problems? Several. For once, what mkzftree does is copy a directory with all subdirectories to another one, with files compressed. Then, with "mkisofs -z ...." I create the iso image of that (I can mix several dirs, compressed and normal). Clumsy... This means that everything has to exist at a certain moment on three copies: original, compressed tree, iso image/s. Then, it is difficult, and I have to do it manually, to adjust what goes on each iso so as to be 700 Mb or as close as possible. Then, a big file would have to be split. Perhaps I could just use a tar/dar file, not compressed, of a size that would fit on a compressed cdrom. But again, I would have to guess the size. Maybe with dar that is not the best thing.
It is really easy for total system backup. I got a cheap dvd-ram (acts exactly like a hard-drive) with 4.5 gigs on each side.
What is a dvd-ram? :-? A dvd writer, perhaps? -- Cheers, Carlos Robinson
