My question is what should I be backing up regarding udev?
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_WRITER
Dump/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
