next in thread | raw e-mail | index | archive | help
It's not like I really know what I am doing or anything---
My first priority in setting up FreeBSD 4.5 was to get my
printer going well enough that I could get hard copy of
things like file listings and man pages. That is going
satisfactorily.
Next priority is system backup. Per the handbook I am trying to
use dump, but not to tape - I don't have a decent tape drive.
However, I *do* have my system set up with mounting frames so
that I can freely swap hard drives. Figure that ought to
do reasonably well. (Anybody got any pointers/experience on
hot swapping hard drives under FreeBSD?)
At the moment my system is on a 6 GB hard drive. I seem to have
succeeded in formatting a 40 GB hard drive as the slave on the
same controller.
So we do
mount /dev/ad1s1e /mnt
and it's there.
Then we do
dump -0u -f /mnt/usr/backup0 /usr
and get
DUMP: Date of this level 0 dump: Sun May 5 21:52:36 2002
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/ad0s1g (/usr) to mnt/usr/backup0
DUMP: mapping (Pass 1)[regular files]
DUMP: mapping (Pass II) [directories]
DUMP: estimated 746212 tape blocks on 19.16 tape(s).
DUMP: dumping (Pass III) [directories]
DUMP: Closing /mnt/usr/backup
DUMP: Change Volumes: Mount volume #2
DUMP: Is the new volume mounted and ready to go? ("yes" or "no") no
DUMP: Do you want to abort? ("yes" or "no") yes
DUMP: THe ENTIRE dump is aborted.
then
ls -l /mnt/usr
-rw-r--r-- 1 root wheel 39260160 May 5 21:53 backup 0
So: How far did I get? What is a good way to check what is or
is not in backup0?
What should I be doing to get the backup I want (preferably
without novice-confusing error messages)?
Should I be doing something else entirely?
Any advice would be appreciated.
