Re: [Veritas-bu] Running bpbkar32 from the command line
Bit of a problem if you've got icmp (and ftp, and...) disabled between most servers clients like we have. Is there anything similar that can work over the NetBackup ports which obviously will be open?

We're trying to do some bottleneck testing and are running into a problem with the FTP ports being closed down on our Windows systems, thus we cannot really test the network between the clients and media servers. We're trying to see if we can kick off bpbkar32 manually to just move a single file to disk on the media server to test the network like and FTP would. I know we test the client side locally by running: bpbkar32 -nocont [file_path_to_test] 1 nul 2 nul I also know that bpbrm is the process responsible for starting bpbkar32 and passes all the information bpbkar32 needs to start the backup. One thought is to enable the bpbrm log file and see what options are being passed, however if anybody out there has already done this and can give me a breakdown of running bpbkar32 manually that would be great!

[Veritas-bu] 6.0 MP3 Bug
We ran into a bug with 6.0MP3 while testing our BMR. The Contents of c:\windows\sysvol gets restored to c:\windows\sysvol\domain instead of c:\windows\sysvol\widgets.ca Symptoms are that you are able to login to the AD server only with cached credentials. All other user accounts don't work. The DNS server also crashes after a bit. In my eyes, this is a pretty nasty bug because you probably can't do an authoritative restore. This could be a BMR restore issue or a NB Restore issue. We currently have an open case with veritas as does one other person.

Re: [Veritas-bu] Data de-duplication solutions
We are currently in the process of testing out Direct Tape Copy on the NetApp NearStore VTL's. The results we are seeing is that we are getting better than 50MB/sec with LTO-3 drives writing to LTO-2 tapes. We can attach up to 3 drives per 2GB fiber-channel port. We figure we can do about 4TB/day per drive or up to 12TB/day for one NearStore VTL. Compare that to the very poor performance of the vault/duplication process which we have found to be on the order of roughly 11MB/sec or about 1TB per day per LTO-3 drive. We are still testing and have not yet made the switch over to this, but right now it looks very promising. If we do make the switch we will not use vault for anything except for maybe container management. --stuart -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of T H Sent: Wednesday, October 18, 2006 6:10 PM To: veritas-bu@mailman.eng.auburn.edu Subject: [Veritas-bu] Data de-duplication solutions Hi everyone, I have seen subjects on data de-duplication here.

Re: [Veritas-bu] Data de-duplication solutions
Yeahthere's a way to scan the physical library and the VTL will create a set of virtual tapes with the same barcodes as the physical tapesNetBackup will basically not know the difference and will treat them the same. I believe that you can always get the data off of the physical tapes if the Nearstore dies. The problem would be if you had not gotten all of the data transferred from the VTL to the physical tapes before the VTL gets hit with some kind of failure. The physical tapes would be used for off-siting. There is a shadow copy feature that will keep stuff on the VTL until the disk space is needed for new backups. So, if you have enough disk you can keep stuff online for restores if needed. If you are getting 30MB/sec to tape with vault/duplication, you're lucky. I've found that it is highly dependent upon the image size and the makeup of the image itself. If you have a number of small images, you will lower the throughput of vault. Also, if you have a large image that is made up of a number of small files, you will also impact the throughput. The best case is a large image made up of large files. Think of it this wayit's like having a couple of fire-hoses for the data flow. One is coming into the media server from the VTL and the other is out-bound to the physical tape drives. Vault/duplication does not allow you to simply connect the fire-hoses. It has to empty the in-coming one and put that data into buckets then empty those buckets into the out-going fire-hose. Ohand while it is filling the buckets, it's doing an audit to ensure that you have the right number (counting the image fragments, etc). The nearstore VTL will actually connect the fire-hoses and you get line-speeds because it's doing the copy at a block-level to the physical tapes. As for the performance into the VTL, we don't really care, because there's no shoe-shining with virtual drives. But we have seen very fast transfer rates in and out depending upon the data source and the connection to the media server. Like 30MB/sec or faster for single streams. And if you add up the throughput of multiple streams for a given source, it's even faster than that. -stuart -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Paul Keating Sent: Thursday, October 19, 2006 10:09 AM To: veritas-bu@mailman.eng.auburn.edu Subject: Re: [Veritas-bu] Data de-duplication solutions So the Nearstore sees the physical tape library and directly copies fromthe virtual tape cartridges, on a 1:1 basis to the physical carts?

Revoking this thread since its absolutely essential to me. I read the mails, went to office and did a grep Kbytes/sec log.100906 in the bptm folder. I found that no single value was above 22 Mbytes/sec, shd that mean
that my vaults are not above 22 Mbytes/sec. Is there anything specific in the log which I can search for clarifying my vault speed.**
