All,
I have been watching this list for the last few months and have found
some good advice. Thanks.
Now I have a situation that I need help to resolve.
I have four RedHat systems that I take care of, two are RH9 and two
are RH8. They are all servers with most everything available
installed. My backup strategy in the past has been to backup all
data files both system and private. Then if there is a failure I
can reload the system and download all the current patches and
updates to the system and finally restore the data files.
Now that Red Hat is dropping support for release 8 and soon dropping
support for release 9 I am faced with the problem of keeping a
complete system backup as well as the data.
I am not sure if I have the knowledge to do this. Can anyone explain
what system files I need to backup so that I can rebuild the system
starting with the RedHat distribution DVDs?
It may be a simple thing but I seem to lack a few of the details to
pull it off.
The problem is in differentiating between what constitutes the OS and
what constitutes user data. Since things can be intertwined (tweaked
.conf files and such), this isn't such an easy thing to do.
I'd back up the whole system, OS and all. During a recovery, you'd
install the OS from CD and RPM updates, then you can restore the files
from the backup set but specify that the system may NOT overwrite
existing files. This will prevent your customized stuff (or older
updates that are on the backup media) from stomping on your freshly
installed system. You can remake your tweaks and make note of those
files. Most backup/recovery systems allow you to say "don't overwrite
any existing files EXCEPT for these", then specify a list.
It all rather depends on which backup system you use. If you can tell
us what you use, we may be able to help.
