I can re-install a lot faster than that. My suggestion would be to do the slicing/partitioning on the copy and then use dump/restore on each partition from the new drive to the copy drive. A dd image is not really all that good a way to do it. It just produces a sector by sector copy which is not efficient. The dump/restore produces what you want which is an efficient runable system on the copy disk. Once you get the dump/restore finished, you could use rsync periodically to keep it up to date. Actually you could use rsync to do all the copying on to the prepartitioned copy drive, but I would prefer dump/restore. > I normally store my image copies on a Samba share on another system, > they are stored as files. I am not copying to another raw drive. In that case, use dump(8) to create those files and store them where-ever you wish. > > Is there an image-copy backup program that understands the UFS > file-system? Or perhaps there is a better solution on FreeBSD? As mentioned above, dump(8)/restore(8) is made for that. ////jerry > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
