Re: [Veritas-bu] 'Frequency' schedule type
I hate to send this out 3 times in a row but it does address the question. Freq ONLY depends on when the backup ends for INTERVAL based schedules. This is what used to cause sliding windows of old. Freq based Freq schedules do not care when the backup last finished. Below is a small write-up concerning the 2 processing types that NBU uses for Freq. based schedules. Freq based schedules can use either Freq or Interval mode depending on the Interval setting that is chosen. Frequency based Sched vs Interval Interval = 24 hour frequency(24 hours, 1 day, 7days ect.) Frequency = Any non-24 hour frequency (12 hours, 27, hours 80 hours ect.) If Interval mode scheduling is used the time of the backup is calculated from when the windows was initially open. So if the window opens for a class-sched at 8pm on a Monday and the frequency is 24 hours but the backup does not start until Midnight the job will be available to run at 8pm the next day. But if the sched was setup to run every 26 hours then that same job would not be available to run until 2am the next day.

Re: [Veritas-bu] 'Frequency' schedule type
Sorry, I had the INTERVAL and FREQ parts backwards and it was not very clear. The write-up below may make more sense: Freq is measured when the backup ends if you are using Freq based scheduling. If you are using Interval mode scheduling when the backup ends does not matter. Its a bit confusing but as everyone knows there are only 2 types of schedules, calendar and freq. But if you chose freq based schedules then bpsched has 2 processing modes it can use and that is freq and interval. Here are a few snips from a verbose bpsched that shows this. 06:03:03 [2116.2240] 4 in_interval_mode: IN INTERVAL MODE . 15:31:26 [1820.1800] 4 in_interval_mode: NOT INTERVAL MODE -- not an integral number of days15:31:26 [1820.1800] 4 backup_due: using frequency-only mode Hope that helps Steve On 5/18/06, Steve [EMAIL PROTECTED] wrote: I hate to send this out 3 times in a row but it does address the question.

Re: [Veritas-bu] 'Frequency' schedule type
bpimagelist returns withthe "start time" of the image. The image name contains the ctime of the start of the image. Because of these reasons, I believe that "Freq is measured when the backup STARTS if you are using Freq based scheduling." But I have no proof and I have read conflicting posts from users using different versions of Netbackup.

RE: [Veritas-bu] Question with bpduplicate.
Justin - NetBackup keeps track of the Primary Copy. All restores are performed from this Primary Copy. In order to perform restores from another copy (not always number 2...), you need to change the Primary Copy to the other copy number. One way to do this is with the following command : bpduplicate -npc new primary copy -backupid backup id Or you could use this command : bpimage -npc copy # -backupid backup_id You can check your Primary Copy number by running bpimagelist -L -backupid backup id and looking for the phrase Primary Copy:. The phrase Number of Copies: will tell you how many copies you have.

I believe I've done the calculations before for the VMS client - the relevant data is logged - and the date used is measured from when the last backup STARTS, not ENDS. If you think about it, it *has* to be this way or you will miss files. eg. differential starts at 12:00 and ends at 18:00. A file is created at 16:00 but the directory it is in was processed at 13:00. If you started your next differential and selected all files since 18:00, you'd skip the file and this would be bad. If you start your next backup and selected the files created since 12:00, you'd be okay. Now of course you could select the same file twice (e.g. if the file was created at 12:05 and the directory was processed at 13:00)) but that's a far better problem than not backing it up at all. -- Ed Wilts, Mounds View, MN, USA mailto:[EMAIL PROTECTED] ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
RE: [Veritas-bu] Upgrade to 6.0
During the test restore we found that we may face data corruption on media since our environment matches to conditions described below: http://seer.support.veritas.com/docs/280140.htm at the end we found that issues with restore were related to bad SCSI cable (backups are 100% good, restores are 100% bad - bad image header reported). But during the troubleshooting we migrated to 5.1 MP5. Next day we noticed an increased number of invalid images reported by 'bpdbm -consistancy 2'. Started to have troubles with bpexpdate and bpimagelist for certain images... Investigation showed that bpdbm dumps core during the attempt to process certain entries in catalog. Solutions: wait until Symantec will fix the daemon with positibilty to have increased number of broken images, downgrade to MP3/MP4 and face potential data corruption on tapes or move on to 6.0 (were ready, internally trained and prepared). To clarify - I'm not 100% sure if MP5 introduced the problem with catalog or we had one before with MP3.. Sorry, had no time to investigate, was too scary to lose data in catalog ...

Hi, I'd just like to verify something. As it relates to windows servers, SRT's are kept on the windows boot server but driver/servicepack packages are kept on the netbackup master. I'm thinking that in the event of a DR, netbackup master is cloned and all i have to do is install a BMR boot server on any computer and add the SRT's. Then the packages should flow from the netbackup master. I know this is changing with winpe boot sometime in the future.

We have DD200's here and they have beentrue to our expectations. We push all of our non-critical, short expiration, jobs to them. We have been happy with the compression and reliability - though we have had a few issues. Nothing we couldn't get fixed. If its not already out there - their newest model allows you to connect to your own back end storage. Would we buy again? Yes.

RE: [Veritas-bu] backup_exit_notify script question
You can't do this with stream number because there's no guarantee what inorder the streams will complete. Most of us have nasty hacks for this. My version has every stream that ends write a line to the same file. Then it checks the size of the file, if the number of lines matches the STREAM_COUNT variable, then I assume its the last stream to exit and it runs the cleanup routine. The line it writes to the file, by the way, is the return code for that stream. The cleanup routine checks for all zeros sends warnings if any of the streams were non-zero exits. -M From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Pero, GregSent: Thursday, May 18, 2006 11:19 AMTo: veritas-bu@mailman.eng.auburn.eduSubject: [Veritas-bu] backup_exit_notify script question Running Netbackup 5.1 mp4 on W3K have backup_exit_notify.cmd configured to send email alerts (based on the status code) via blat to the NB Sys Admin.

As a result of customer satisfaction surveys and feedback collected from various customer channels we are building a more robust self-service experience for you, our enterprise support customers. The first, and most visible, part of this new experience is the introduction of an entirely new search engine designed to bring you the right answer faster and more reliably than ever before. This new search engine is based on Natural Language Processing (NLP) technology. Unlike an imprecise keyword search engine, our new NLP works best when it has more details. For example, in the past, a search for drivers might have yielded a range of documents related to the download, installation, update, or driver related errors on a target system. There were too many results, and the required document may have been far down the list, requiring valuable time and effort scanning results. With the new search engine, you are free to ask for exactly what you want and limit the results to only those that matter. For example, if you are looking to download drivers ask Where can I download tape device drivers for Backup Exec version 10? and get just a few very specific documents in return. As mentioned above, our new search is a Natural Language Processing search engine and works better with questions or phrases than with a keyword style search. Providing more words is better, and questions or multiple keywords will elicit better results than one or two key words.For further tips please click on the Search Tips link on the Enterprise Support landing page.In the end, our mission is to deliver the right answer as the top result for your specific question. Your issue - your words - your answer. Quick and painless problem resolution at a pace we expect will set a new industry standard.On behalf of the Engineers and Management at Symantec Corporation, thank you again for your loyalty and patience as we undertake this ambitious project.

RE:[Veritas-bu] Netbackup PureDisk vs datadomain / Diligent..
Hi, We are also looking in D2D solution which work with netbackup. We are going to make decision between DataDomain and Dilligent. This is my thought about these two products. Dillignet: Pro: VTL - low impact on configuration. faster - it use fiber channel. more add on functions - there are some good add-on functions you can buy from diligent. Con: costly - Software: Netbackup VTL license, Diligent license, Redhat RHEL 64-bit license. Hardware: 64 bit AMD server, disk storage. If you don't have san, you might need a fiber switch. Datadomain: Pro:Simple, no software license needed. Con: Not expendable, if you run out of space, you screw up. Netbackup PureDisk: PureDisk is like a separate software from Netbackup. You can have a lot of choice if you want to look into different D2D products. PureDisk only support windows client.

We have a couple of polices that do a full backup weekly, with the frequency set to 1 week. However, the jobs didn't run on the weekend; there were no errors, they just didn't run. The only reason I can think of this happening is the job falling outside of the start window. From what I've read, the frequency is the minimum amount of tim that must pass before the next schedule runs, which means that we should probably set the weekly jobs to having a frequency of 6 days to avoid it falling outside the start window.

Not necessarilly. :-) We can calculate the time to start our job based on the end time of the last job, while still using the start time of the last job for calculating which files to backup.

The image name contains the ctime of the start of the image. Because of these reasons, I believe that Freq is measured when the backup STARTS if you are using Freq based scheduling. But I have no proof and I have read conflicting posts from users using different versions of Netbackup. I believe I've done the calculations before for the VMS client - the relevant data is logged - and the date used is measured from when the last backup STARTS, not ENDS. If you think about it, it *has* to be this way or you will miss files. eg. differential starts at 12:00 and ends at 18:00. A file is created at 16:00 but the directory it is in was processed at 13:00. If you started your next differential and selected all files since 18:00, you'd skip the file and this would be bad. If you start your next backup and selected the files created since 12:00, you'd be okay. Now of course you could select the same file twice (e.g. if the file was created at 12:05 and the directory was processed at 13:00)) but that's a far better problem than not backing it up at all. -- Ed Wilts, Mounds View, MN, USA mailto:[EMAIL PROTECTED] ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu

Re: [Veritas-bu] 'Frequency' schedule type--let's get it right
frequency is measured from when the backup ends Many posters have made this statement; please state your sources as this is demonstrably false. Policy Name: DEMO-prod-std Include: / Schedule: full Frequency: every 1 hour Daily Windows: Thursday 09:00:00 -- Thursday 19:00:00 Backup ID: someserver_1147969653 Policy:DEMO-prod-std Sched Label: full Backup Time: 05/18/2006 11:27:33 Elapsed Time: 000:04:16 Backup ID: someserver_1147973257 Policy:DEMO-prod-std Sched Label: full Backup Time: 05/18/2006 12:27:37 Elapsed Time: 000:03:04 The reason schedules slip in NetBackup (pre-NetBackup 6) is the scheduler wake-up interval of ten minutes (default) and scheduler workload. The time from the ideal frequency plus last start time (say, 24 hours and 18:01:33) until the next time the scheduler wakes up after 18:01:33 the next day is the earlies the job can be scheduled. On average, a schedule would slip five minutes per day (potentially missing a window). This (and the I ran it as a test yesterday morning so it didn't run last night oversight) are why setting the frequency to the window size became popular. support.veritas.com/docs/209227 This was addressed in two ways that I know of: 1. logic was added (4.5? 5.x?) to check the frequency for exact multiples of a day, and start those backups at the beginning of the window each time--it's interval mode which another poster spoke to this earlier. (I believe this is covered in a technote but I don't have it.) 2. NetBackup 6 sets an alarm in advance for when backups are due rather than check for this every ten minutes, IIRC from training materials. ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
