I'm working to maximize throughput from a Win2K system, which backs up
our two NetApp systems through mapped drives. When I do this using one
data stream per filer, it takes 66 hours, and the tape shoe-shines quite
a bit. I have built a file list that breaks some top level directories
into mostly equal "NEW_STREAM" data streams, so they all seem to finish
within an hour of each other. This keeps the tape drives moving data
nicely. I have written a Perl for Win32 script that scans the top level
of each of my NetApp servers (through the mapped drive), and outputs a
file format that matches the format used in the configuration on the NB
master server. This would work well in a static environment, but one of
the NetApps contains user home directories. This changes sometimes
without my knowing it.
I don't see anything on the Veritas support page regarding the creation
of a dynamic file include list that can contain the declaration of
"NEW_STREAM". I would like the ability to launch the backup, and have
bpstart_notify dynamically create an agressive file list, and begin the
backup.
Does anyone do this already?
NB 4.5, Solaris 9. All media servers are sun. LTO-1 drives.
I immagine it's possible to push the dynamic file list from the client
to the master server, but that would expose the master server, and some
very sensitive config files.
