I'm aiming to use Amanda for bare metal restores as described in "Backup &
Recovery" by Curtis Preston - p. 145. However, I'm not sure which
directories to exclude. In fact, I'm not sure that I should exclude anything
at all. Should I exclude these?
/proc
/mnt
/dev
/tmp
/sys
With the possible exception of local usage of /mnt,
all of these are temporary or dynamic or pseudo
file systems or directory trees. Don't back them up.
It depends. /dev may be real.
do a `df -k` and see.
I've done basically cold metal from tape a number of times on my Suns.
So, I'm using ufsdump which may differ somewhat from what you are doing.
However, in my case, I'm catching the partitions that are actually
/dev/dsk/cxtxdxsx. So, for my backup server:
mormyrid:/usr/local/etc/amanda:amanda$ df -k

I basically only need "/" and "/usr/local".
The recovery of "/" captures all the mount points. Booting the system
reconstructs the contents of all the other stuff. In my case, the
/var/spool/amanda stuff is dynamic and doesn't need to be backed up or
recovered. It's possible that I could lose stuff off my holding disk in
a disaster, but that is stuff in the process of being backed up. So it
makes no sense to think about backing up and recovering that. And my
/archive is stuff that is getting pushed over to another server (all my
amanda configurations, indexes, etc.)
Hope that helps. Now I have to go tend to my turkey. For those of you
not in the U.S., please excuse us for dropping off the activity charts
for a day or so. It's Thanksgiving. ;-)
