Plus "par", that I still > haven't evaluated. kdar is the frontend to dar... after looking at it in more depth it became apparent that one would still have move the dar slices to an iso image and the iso image would then need to be burned. A further complication is although kdar apparently offers a 4Gb slice size for DVD the dvdtools burning tools will only accept a max of 2Gb per file (slice). (And not even that... setting slice size to 2Gb still caused problems). To get a listing from a dar rquires access to first and last slices, this would suggest the for an N slice backup one would need (N mod 2) + (N div 2) DVDSs for a two slice solution with first DVD containing slice 1 and slice N, kdar provides no mechanisms for such slice management across media. While a bulk restore would be ok do not think this would work to well for retrieving a single file (one would not only have to know which slice a file was in but which DVD, and heaven forbid if the file is split between two slices on two DVDs). dar has some other limitations as well which took it out of picture....
A brief look at par (which dar seems to link into) suggests this not suitable for my requirements... What I intend to look at is the possibility of using to rdiff-backup to build its structures and create a tar image of this structure (which probably be ok for disaster recovery but not brilliant for archive retrieval). Dirvish is impressive but I think it would best with a SAN or dedicated backend backup server solution. > > And there are some other solutions in the distro, I think. > I have been looking... I dunno after years of being a sys-admin one of things that still seems to give the most grief is backup >:o -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
