You imply that, on a running system, /dev/.static/dev should be backed up as /dev.I don't have a problem with how to do this; I'll archive the dev stuff along with other meta-data and stick it at the head of my archive, like:cd /dev/.static && \ find ./dev -xdev -depth -print \ | $CPIO > $TMPDIR/dev.cpio cd / && \ find ./$TMPDIR/README ./$TMPDIR/ARCHIVE_DATE ./$TMPDIR / \ -xdev -depth -print \ | $CPIO | $MEDIA_WRITERDump/restore is slick but I see it as only good for supporting a system. I like my backups to also be suitable for use as a information archive. I've settled on cpio archives for portability. It is bad enough trying to find a working 5-1/4 drive or a 60meg 1/4 inch tape drive, without trying to find an operating system that has a filesystem and version of restore that match some 15 year-old archive.Thanks for the reply; I didn't realize that about dump. Be well, rir
I can't add anything to the discussion re. /dev, but am curious about your reference to "a working 5-1/4 drive or a 60meg 1/4 inch tape drive,".
Since most hard disks are now less than 5-1/4 inches, are you referring to floppy disks? And that tape size is ancient, I think.
If you have access to either a CD or DVD burner, you might want to look into cdbackup/cdrestore (package name is cdbackup, IIRC). From the man page:
DESCRIPTION
cdbackup is a utility to make streaming backups to
CD-R(W)/DVD-R(W) disks. It’s designed to work with any backup
tool which writes the backup to stdout (like tar/cpio/afio).
