Backing up under Domain/OS

[Aaron Fein]

I am looking for documentation covering how to backup under Domain 10.3. I
am told that we should have all of the documentation, but I have not been
able to find much more than a brief example of the wbak command. I need
documentation on both backing up and on preparing a boot tape for disaster
recovery. If someone could provide me with a list of the HP documents
covering this material that would be great (part#(s) would be appreciated).

Thanks,

Aaron

Wbak works fine for Domain file systems, but won't do NFS.
You want to use options like -hi/-nhi, -full/-incr to tell it
what to do, and be able to do incremental backups easily.
Don't forget -no_eot if you are using c-tape, so you can add
another image with '-f cur'. For the restore, using rbak,
look at -sacl and -pdt. I seldom do backups with absolute path
name so files can easily restored elsewhere.

I haven't ever made a boot tape for disaster recovery, since it is
probably easier to just reinstall from the Authorized Area.
I do have a backup of the "modified" files so I can easily put a
node back the way it was - I can send you (or post) my script that
does this backup, which must be kept on media that can be accessed
easily from a freshly installed system (I use c-tape).

HP sells Omniback for Domain and NFS backups, and Workstation Solutions
also has a universal backup product - both cost big bucks for a small
network, and won't work well in a really heterogeneous network (you end up
backing up over NFS which is bad news performance-wise). Both have
backup agents that run locally on Sun and HP-UX as far as I remember.
