Re: [Veritas-bu] Unsupported file system type in BackupExec
Update: After the upgrade to 6.5.4 I can import all the BackupExec images. I can restore files from the BackupExec backups It seems that you can't restore Exchange 2007 VSS BackupExec backups to the Recovery Storage Group Michael 2009/7/9 Michael Graff Andersen mia...@gmail.com Thanks, actually I only found an old technote regarding Unsupported file system type :47 Seems that I should upgrade to 6.5.4 to get BackupExec images imported Then if I still have problems it is certainly worth a support case Regards Michael 2009/7/8 bob944 bob...@attglobal.net I am getting the following: 18:03:22 INF - Skipping Backup Exec backup having backup set number 180.

Unsupported file system type :47 when I import some BackupExec tapes to Netbackup 6.5.3 and wonder what I'm not getting in. Can anybody shed some light on this as the Symantec webiste wasn't very informative Technote http://support.veritas.com/docs/295433 is the one that rules--I assume you found that? A BE admin was able to tell me what was on tapes I was trying to import, by which found that type 47 is a Volume Shadow Copy type.and I had other type numbers that corresponded to other Microsoftisms, like System State. None of the unknowns were filesystems or SQL Server, which is what I was after. The technote has been updated with 6.5.4 info; you should now be able to import BE VSS and System State, and w2k8 and compressed in case your type 59 and 70 are one of them. Worth a tech support call? ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
[Veritas-bu] Question when importing tapes [expiration dates]
Hello, Had a quick question, when importing tape media that may have already expired, during the phase1/phase2 import, does it reset it in advance or does it re-expire after you import it? Should one suspend the media first? What is the recommended procedure?

[Veritas-bu] Netbackup 6.5 upgrade qs
One thing to keep in mind that it is critical to go through the steps of running catalog consistency tests. I had tons of problems with this (100+ GB catalog space). And never got the catalog into a state that we could actually upgrade our 5.1 MP7 in place. It would have taken us an estimate 4 - 5 days of downtime to actually complete the upgrade. The catch was having to go through Symantec support to check and fix any catalog inconsistencies. That was a tedious process (run the test, send the output, receive a fix file, run the fix file, repeat, repeat, repeat). Every time I would get to a consistent state, I ran out of my upgrade window. I ended up creating a new environment running NBU 6.5.3 and migrating media servers and clients over. I'm just now finishing that up after 8 weeks of effort. Should be done by the end of this month. Oh, and I've been consolidating the long retention period data on the 5.1 environment to tapes that I can then import into the 6.5 environment.

Re: [Veritas-bu] Question when importing tapes [expiration dates]
Someone can correct me if I'm wrong, but the way I understand it is when you import an expired image, the imported image is set to expire based on the original retention setting plus today's date. So, for example, if you had a series of images that had a 90 retention and you imported them today, the new images would be set to expire on October 10, 2009. As far as suspending the media first, I can't remember if Netbackup is picky about media state. I'm pretty sure it can't be frozen, but beyond that I don't know. Hope I kind of answered your question. - Heathe Kyle Yeakley On 07/10/2009 08:44 AM, Justin Piszcz wrote: Hello, Had a quick question, when importing tape media that may have already expired, during the phase1/phase2 import, does it reset it in advance or does it re-expire after you import it?

[Veritas-bu] Question when importing tapes [expiration dates]
It will reset the expiration to the future. Think of if like the images on that tape were all backed up at the time of the import. The expiration date is then recalculated based upon that import date. It's a pain but if you are aware of if you can work around it. I've frozen the media (suspend will work also) after performing the phase1 import. Good idea to prevent NBU from adding data to the tape. If you know which images have expired, you can do a more selective phase 2 import just importing the images you know that have not expired. jpiszcz wrote: Hello, Had a quick question, when importing tape media that may have already expired, during the phase1/phase2 import, does it reset it in advance or does it re-expire after you import it?

[Veritas-bu] Using multiple drives with NDMP.
Jeff,
I've had some experience with the Celera NAS devices. There is a parameter you
need to set that must match the SIZE_DATA_BUFFERS_NDMP. I changed the
SIZE_DATA_BUFFERS_NDMP without configuring the Celera and all my NDMP backups
started failing. I'm sorry, but I don't remember the parameter on the Celera.
I had found it, was planning to make the change and got side tracked with
something else. That was a couple of months ago
javascript#058;emoticon(':?'). It was pretty easy to find in the Celera admin
guide. I'll see if I can dig up that config information for you.
jeffc wrote:
Boris,
When I was doing some testing earlier I could see in the logs that the buffer
sizes were only changing when I modified the size_data_buffers_ndmp value. If
there is a way to set the size on the Celera I would guess that would work as
well. I haven't figured out how to set the MOVER_RECORD_SIZE on the NetApp.
I'm kind of hoping that the value being passed by Veritas using the
size_data_buffers_ndmp value is setting it.
Thanks,
Jeff

Hi Im new to netbackup and want to understand about archiving. we have 2 policies in my netbackup 6.5 enviornment. Policy : Archive1 Type : Full backup Backup selection : F:\archive Policy : Archive2 Type : Full backup Backup selection : F:\archive As per info provide to me , first archive1 runs and data is backed up on achive tape1 and then archive 2 polict runs and it same data is backed up on archive tape 2. Archive is kept onsite and Archive 2 tapes are sent offsite. If both archive backups gets successful, data from the folders gets deleted if one of them fails, data doesnot get deleted from archive folder. When I see these archive policies, these are normal policies. My question is how does this process works? I belive its the OS who delete the data from Archive folder, but where is this information passed from Netbackup to OS? As said prev, im new to Netbackup, might be its a silly question, i thought its better to ask.

[Veritas-bu] Tape Drive Statistics
Hello group, I am trying to performance tune a new library I installed. I have the performance tuning guide and I'm looking at my data path. I currently have statistics on my tape drive (from the libraries point of view), stats from my SAN switch, and stats from my LAN. I'm watching iostat for the disk that I'm writing to, but I'd like to see the performance of my tape drive from my Master server's point of view. I don't believe iostat accepts tape drives. How do you measure tape drives statistics in Unix/Linux (specifically RHEL). On a side note, I'm reading up on how to tune SIZE_DATA_BUFFERS and NUMBER_DATA_BUFFERS. If I'm watching statistics in real time for my performance tuning backups and restores, can I change these values in real time without having to restart Netbackup (or any of my master/media/clients) and see the results take affect, or do I have to restart services for the new values to take effect?

Where do I go to find the tape I/O size? And where do I find the tape I/O size supported by the tape drive and OS? My configuration is: Windows (earlier versions had an issue where the driver could only do 64k) that is probably what it is referring to. Tape Drives: LTO-4 IBM # or drives: 6 Master Server OS: RHEL SAN Media Server: Tru64 Library Vendor and Model: Spectra Logic T380 Would Red Hat, IBM, Spectra Logic or the LTO site have the supported tape I/O size numbers? Thanks. - Heathe Kyle Yeakley After you read many of the white papers and perform testing, you will find what best works for your environment: Here you go though, as you asked for it, page 39: http://www.sundds-lto.com/uploadLinks/Gen3_Performance_Wpaper_OEM_AQ_Feb05_final.pdf Some other/more info: http://h71028.www7.hp.com/ERC/downloads/5982-9971EN.pdf In addition, most backup application software allows the block size on tape to be changed. For all HP StorageWorks Ultrium 960 backups, HP recommends the tape block size/transfer size be configured to 256 KB. In general, (IMO) in my environments I find 256kb with 32 buffers optimal for LTO-4 drives, as you have in your environment. Once you pick your size_data_buffers, you want to keep them the same. Most people tune to 256k and are good. I have seen 90-93MiB/s with that setup on LTO-3 (uncompressed) and sending compressible data I have pushed 127-130MiB/s.

[Veritas-bu] Reusing an old LTO3 FUP (Firmware Update Tape) for data...
I have a LTO3 FUP tape and would like to use it for data again. How can I convert it? I'm using two StorageTek SL500 libraries along with a standalone drive. +-- |This was sent by lee.rai...@motorola.com via Backup Central. |Forward SPAM to ab...@backupcentral.com. +-- ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
Re: [Veritas-bu] Tape Drive Statistics
I use iostat -xzn #, where -x shows disk, -z omits devices doing nothing (having all 0's) and -n shows names of the devices. Tapes are included in this output, but this is for Solaris.

I have the performance tuning guide and I'm looking at my data path. I currently have statistics on my tape drive (from the libraries point of view), stats from my SAN switch, and stats from my LAN. I'm watching iostat for the disk that I'm writing to, but I'd like to see the performance of my tape drive from my Master server's point of view. I don't believe iostat accepts tape drives. How do you measure tape drives statistics in Unix/Linux (specifically RHEL). On a side note, I'm reading up on how to tune SIZE_DATA_BUFFERS and NUMBER_DATA_BUFFERS. If I'm watching statistics in real time for my performance tuning backups and restores, can I change these values in real time without having to restart Netbackup (or any of my master/media/clients) and see the results take affect, or do I have to restart services for the new values to take effect? Anyone have tips on how to tune these values? Thank you. - Heathe Kyle Yeakley ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
