Re: [Veritas-bu] bpduplicate
http://www.definethat.com/define/6002.htm
A {Unix} {system call} used by a {process} (the parent) to make a copy
(the child) of itself. The child process is identical to the parent
except it has a different {process identifier} and a zero return value
from the fork call. It is assumed to have used no resources. A fork
followed by an {exec} can be used to start a different process but this
can be inefficient and some later Unix variants provide {vfork} as an
alternative mechanism for this. See also {fork bomb}. (1996-12-08)
However, the only reference to fork in either NBU 6.5 or 7.0
Command manual are only related. See bpcd(1):
-debug
Available only on UNIX clients and implies -standalone. This option
prevents bpcd from forking and does not disconnect it from standard input,
output, and error.

Hi All,
A couple of irrelevant questions. Does anyone know what the -fork option
is? Is the -X used to set the dates to Unix time format?
I am only the one that just discovered how to see what commands jnbSA
executes? :(
Does anyone know how to do the equivalent from windows?

Re: [Veritas-bu] How to use different network interfaces
All, HP-UX calls their product Auto Port Aggregation (product number J4240AA). It is a separately licensed product and is priced on a sliding scale, depending upon the size of the computer it will operate on. HP claims to be able to configure up to 50 aggregates per system. (Product Brief: http://www.hp.com/products1/serverconnectivity/adapters/apa_prodbrief.html) This is the same as what Solaris call Trunking, though they support up to 8 links trunked into one logical IP address. Solaris 10 provides this as part of the OS. Earlier versions charge for the software. This function is referred to as teaming, trunking, link aggregation, etc... It is important to note that you must work closely with your IP Networking Team. The ethernet switch ports to which you connect the multiple physical interfaces you are trunking/aggregating must be configured to recognize this. Cisco refers to this as trunk groups. Extreme Networks refers to trunking. Make sure the network switches your servers connect to can accomodate this type of trunking, and that your IP Networking staff can provide this service. -- Michael F Lavelle 100 Abbott Park Rd Office (847) 937-1195 Infrastructure Architect AP14B-1 GB16Cell (847) 553-5158 CIT Storage Engineering Abbott Park, IL 60064-6042 [EMAIL PROTECTED] Curtis Preston [EMAIL PROTECTED] Sent by: [EMAIL PROTECTED] 11/04/2007 10:46 PM To Martin, Jonathan [EMAIL PROTECTED], Barber, Layne Mr CTR US DISA CDM2 [EMAIL PROTECTED], Veritas-bu@mailman.eng.auburn.edu cc Subject Re: [Veritas-bu] How to use different network interfaces If you can figure out how to do THAT, it would certainly be preferable to the NBU method. --- W.

I have a master/media server with an STK L180 library and an Scalar24 library. The L180 is used for “normal” backups. The Scalar24 (which has only 2 LTO-3 drives) was added as part of a special project to migrate several clients to a different location. Basically backup those clients, send the tapes to new location and restore the data. In an effort to increase the data through-put, I added 2 additional GB network connections. So now I have the following interfaces: Jac01.x.x.x Gigabit (original interface for non migrating clients) Jac01v1.x.x.x Gigabit Jac01v2.x.x.x Gigabit How can I best configure NBU to have as much data as possible stream to the 2 LTO-3 drives in order to speed up the backups? I know I could create an STU on each interface and set the policies to use them, but that would seem to just make the jobs wait as other jobs tie up the drives. What about using the “specified network interface” for the clients? If I do that, how can I verify that the data is actually moving on the new interfaces instead of the original? Help?

RE: [Veritas-bu] Ethernet port aggregation for performance
Paul, Under Solaris 9 and earlier, the Ethernet trunking software is a priced item ($995 list). Under Solaris 10, it is available as an unpriced (free) software add-on. Further, you may be using a Solaris 9 (or earlier) system as a master server with some success. However, SunOS 5.8 has serious known defects in it's TCP/IP implementation, which SunOS 5.9 corrected to some degree, but still has performance problems due to the STREAMS-based TCP/IP software stack. If you want to use a Solaris sparc/x86 NBU Media Server, upgrade it to Solaris 10 before you do anything else. Solaris 10 GA implemented the first of 3 phases of the Solaris Fire Engine rewrite of the TCP/IP software stack. The second phase, where the streams layer is completely removed, not only from between IP and TCP, but all the way up and down the stack, and IP modules call directly to TCP modules (and vice versa) in a lock-less redesign of the software stack is implemented in the current Solaris 10 01_06 release. See page 9 of the FireEngine document listed below. Here is a list of on-line publications which you will find of interest. They will pay you back the time spent reading them: http://www.sun.com/bigadmin/content/networkperf/FireEngine_WP.pdf FireEngine - A New Networking Architecture for the Solaris Operating System http://www.sun.com/blueprints/0404/817-6925.pdf Maximizing the Performance a Gigabit Ethernet NIC Interface (April 2004) http://www.sun.com/blueprints/0203/817-1657.pdf Understanding Gigabit Ethernet Performance on Sun Fire Servers (February 2003) http://www.sun.com/blueprints/0704/817-7526.pdf Ethernet Autonegotiation Best Practices (July 2004) Also, take a look at http://www.sun.com/bigadmin/content/networkperf/ for several other documents which may get the community off their collective fanny and upgrade to Solaris 10. It's been GA for a year. If you want HP-UX TCP/IP performance at half the price on a Solaris box, you don't need to buy a new server. Just upgrade your current sparc/x86 servers to Solaris 10. The 3rd and final phase of FireEngine/FireHose is implemented in Solaris 11. This is available in unsupported form on the Sun Solaris Express site. I've built one Solaris 11 beta system, but have no performance numbers on this yet. I'll forward performance numbers to the mailing list in the next few weeks as I compile them.

RE: [Veritas-bu] on the subject of disk based backups....
Another serious issue which may cause the proliferation of Volume Pools is business litigation. If your business is the victim of law school graduates, Volume Pools which segregate tainted from untainted data/applications/servers can be an effective way of containing the potential damage. It can also serve as a mechanism of measurement to charge back to the legal department for the cost of tapes required to satisfy external and internal data retention obligations. This is closely related to different retentions, but goes much further.

Reasons for mulitiple volume pools: different retentions 1 group of servers has a separate pool for Full and incremental – reason is, they require sending Full Backup tapes, occasionally, to our DR site to restore to servers there. They use those servers to test maintenance and so require them to be restored from the production server backups. We use bpduplicate to make a copy before sending them to DR site. When they were in the same pool I had trouble getting everything on the tape copied in a timely manner. Better option is to have enough tape drives to create 2 copies but we don’tL. We use bpduplicate to copy almost everything. We keep a copy on site for a short period of time while sending a copy offsite everyday. Separate pools allows more than one dup job to run, from cron, after the backup window. Multiple media servers – you might want to easily see which media belongs to which media server.

We have one pool for Exchange backups, and three others to go with our Iron Mountain weekly rotations, but I'm not sure what that's buying us. For tracking Iron Mountain boxes, we use volume groups, so the three pools for that are redundant. It's nice to be able to easily break out the Exchange tapes, but there are other ways of getting that information. So I don't think the case for separate volume pools is all that compelling for us.

Re: [Veritas-bu] RE: Searching a command to deactivate all polici es
If you don't need to script the deactivation and don't have constraints on Keywords associated in the Policies, you can use the Admin Console GUI. First, update the individual intentionally deactivated policies to include INACTIVE (or another mnenomic) in the Keywords of those policies for something obvious and sortable in the Keywords column. Then highlight all the active policies and inactivate them. Later, you just go back and reverse the process, eliminating the INACTIVE policies from the activation process. This really is a design flaw of the current implementation. From v5.X on, previously available methods of suppressing job launch were no longer available.
