Re: [Veritas-bu] Deduping with Tape as a final destination
As I understand the PureDisk product, yes. The copy that goes to tape will be the full data set. I believe the product is positioned save space and time from the client and on the equivalent of a DSU. You can run PureDisk along with NBU, so the stream of data that comes from the client is inspected for duplicate data (on the media server), and then space is saved. As a PD client, it inspects data at even smaller chunks, but does the work at the client and sends the changes to the PD repository. I looked at the Commvault 7 documentation, and it was not obvious to me what the contents of the final tape copy would be. If I were going to use tape as a final resting place, and use slow cheap disk as a de-dup location, I would like the tape copy to be the simplest format possible for reading in the future. And it would be nice if those archive tapes did not need a complex road map of re-dup chunks to assemble the data. On a PureDisk server, you can eliminate duplicate data from all your client images, because at any time you can get that data back from the single instance which lives on your random access media. I'm having a hard time conceptualizing the process by which a 100G client de-duped down to a 20G backup tape would be processed for a restore. The bits have to come from somewhere, which is why I'm a bit confused on how Commvault is doing it. I need to read their docs again. -Jon > So, ultimately, the data copied to the tape will be the full amount of the > data and not the deduped data?

Re: [Veritas-bu] Netbackup Health Check Script
Hello Larry, An interesting list. if you have clients/servers behind firewalls you may not be able to use the ping command as the firewall may block. This is for questions 1 and 13. If you are at level 6 you can use the /usr/openv/netbackup/bin/admincmd/bptestbpcd command to check that the clients can talk to netbackup. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Larry Mascarenhas Sent: Saturday, April 26, 2008 6:02 PM To: veritas-bu@mailman.eng.auburn.edu Subject: [Veritas-bu] Netbackup Health Check Script Hello, I'm writing a Netbackup Health Check Script to "proactively" check the status of my infrastructure.

[Veritas-bu] Top 20 (or so) misunderstood things about NBU
People need to stop looking at backups as "backups". People and management need to view data backup as "data protection" and recovery. If you really think about itit's reall DATA PROTECTION and the true test of your Data Protection process is called "Data Recovery". If you can't recover? Then your Data Protection Process is badly broken. nuff said. :D +-- |This was sent by [EMAIL PROTECTED] via Backup Central. |Forward SPAM to [EMAIL PROTECTED] +-- ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu

[Veritas-bu] Terminate backup job after a specified amount of time
Hello, I have a scenario whereby after a specified amount of time (say 8 hours), I would like to terminate the backup job. At this point, we're entering the market hours and backups need to be stopped. Is there any available methodology in Netbackup to interrupt the backups after specified amount of time / at a specified time? If there isn't, I'm looking for pointers as to how to identify the parent job (Gui is too easy. I'm looking for command line to script it) and from there get the time. Any other way to do this? I know that the status of the backups that have already taken place (especially DBs) is no use. And yes, I'll have to visit it and make it faster/change start times etc etc. -- Larry Mascarenhas [EMAIL PROTECTED] ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
[Veritas-bu] Deduping with Tape as a final destination
So, ultimately, the data copied to the tape will be the full amount of the data and not the deduped data? For example, the original 100GB deduped down to 20GB will be the full 100GB and not the 20GB? Or will it be the 20GB, with Netbackup referring back to the index and/or base data?

[Veritas-bu] Storage unit groups are not understood - yes I'm puzzeld
In the relms of the Top 20 (or so) misunderstood specifically #2. Storage unit groups are not understood. (version = 6.5.1) I'm still puzzled. If you have policies pointing to the same storage group with two policies running with the a couple of streams each. Then a third starts it ends up by queueing. The only difference being its not NT Windows but a Standard Unix policy. Rentetion time and media pool the same. Can only a limited number of Policies actually use the storage group at any one time, even if the retention time and tape pool the same? Does the same apply for storage units? If you have a stroage unit like below I would expect you could have two policies writng to it at the same time (with no queueing ) as long as there less than a total of 10 streams. Policies with media multiplexing of 10 and same retention and pool. Storage Unit: Multiplexing enabled Maximum concurrent write drives: 1 Maximum streams per drive: 10 I have set it to one as I don't what to multistream to more that two tapes drives in the storage unit group. Storage Unit Group (set to "balance load" ) has two storage units of the above i.e a max of 20 streams i.e it will do twice the work load of my example I'm assuming each stream is a "job". In the manuals what is a "job" seems to change with context. Max client streams = 24 (for slow backups of small servers) Am I missing anything?
