Well, restore(8) is the utility intended for looking at and extracting files from dump files. I don't know if you can do all those things directly from a dump file using restore. You may have to restore a file to disk first and then act on that file for some of them. But some might work. I usually make a directory I call 'unroll' somewhere with lots of extra space, put stuff there and work on things from there and clean up afterwards.

For some reason I thought restore had to actually restore all the files, as in expand the dump into a collection of files and directories.

For example, if I took a dump 0 of /usr (which I did), I would like to see the "file" /usr/home/nlandys/.zshrc inside the dump, and then actually see (read) this file and/or copy it over scp or to another filesystem. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Your dump is just a regular file sitting on a hard drive with a file system that's already mounted. If you created an on-disk ISO image of that file, you'd have to mount the file system of that ISO image to read the file. If you burned the ISO image to a CD, you'd mount the CD's file system to read it. Either way, the file remains just a file, and is read using restore(8). I'll offer a guess that you're confusing things with tar(1) (which is often used for backups) and the recent changes. From the manpage: This implementation can extract from tar, pax, cpio, zip, jar, ar, and ISO 9660 cdrom images and can create tar, pax, cpio, ar, and shar archives. The above means you can now do nifty things like 'tar xvf mybackup.iso', and if you've configured a pre-processor for less(1), even niftier things like: less backup.tar.gz less backup.zip less backup.iso It's also possible you might be thinking of file system snapshots (which can be mounted).

I have never heard of this. You can put a dump in an ISO, but I don't think a dump is directly mountable. I think you have to create the ISO with the normal makeiso. Then, it might be mountable. But, I could be wrong. jerry > I took my dump > in the following fashion: > > dump -0Lan -C 16 -f - /usr | gzip -2 | > > So, I have a file named dump0-var.gz. > ___ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org" ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
Mount dump0 as ISO9660 filesystem?
I heard somewhere that you can mount a dump as an ISO9660 filesystem, but I cannot find any Google answers on this subject. I took my dump in the following fashion: dump -0Lan -C 16 -f - /usr | gzip -2 | So, I have a file named dump0-var.gz. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
