Re: [Veritas-bu] NBU Flashbackup vs Normal Backup
Flashbackup backups data by reading block after block (physical order). If a file is not stored in consecutive blocks on disk it will not be stored in consecutive blocks on tape. If you restore such a file the data has to be collected from different positions of a tape or, even worst, from different positions on multiple tapes. That of course leads to slower file restores, although NetBackup does a great optimization job on that. This disadvantage is as bigger as more fragmented your data on disk is. On the other hand, if you need to restore the whole disk it will be much faster, because you read consecutive disk blocks from tape and there is nearly no disk positioning necessary.

You mention for single file restore require various tape positioning, meaning to restore 1 file, it need to position the tape afew time before restoring the entire file? whereas a normal filesystem backup when retore a single file only require 1 time postioning? So the multiple times taken for the positioning wil affect the overall restore timing? Ueli Schweizer wrote: Data fragmented on disk will also be backed up fragmented using Flashbackup.

Re: [Veritas-bu] Question regarding Media Status.
Dan, As you mentioned FROZEN state is usually set if there where i/o errors. FROZEN tapes never expire and are used only for reading, not for writing. SUSPENDED is set when NetBackup finds other data than the expected on a specific location on tape, e.g. NetBackup expects an empty header but reads a non-empty header. This can happen if you e.g. add a tape from another NetBackup environment. SUSPENDED tapes are used for reading, not for writing. As soon as all images on tape has expired the tape is returned to Media Manager. MPX stands for Multiplexed. Data on this tape is multiplexed There are additional status like FULL for full tapes, IMPORTED for imported tapes. Tapes that contains non-expired images but are not full yet have status ACTIVE. This is not shown in NetBackup, but all tapes shown not as FULL within bpmedialist are ACTIVE. Tapes that does not contain any active data have status AVAILABLE. These tapes are not shown by bpmedialist. Combinations are possible, however the combinations FROZEN and SUSPENDED is not possible. Cheers, Ueli Schweizer CTO AGITE Software AG Boesch 43 .

Re: [Veritas-bu] scratch pool compliance
Hi Jerry There is no way to have NetBackup erase the tapes when they are recycled. But of course it's possible to write a script. A possible way could be: Use bperror -media to find the tapes moved to the scratch pool last 24 hour. Use bplabel to label these tapes. This will not overwrite the data on tape but will write an EOT marker after the NetBackup label. It's quite difficult (but not impossible) to retrieve data from this tape. If you want to overwrite the data: Mount the tapes using tpreq and write any useless data to the tape, e.g. using dd command. If the tape is completely overwritten you will get a write error. After overwriting the data the tape should be labelled. If you need assistance writing such a script you may contact me. BTW: Some people think it's necessary to write multiple different patterns to a tape (or disk) to completely destroy the data. Cheers Ueli Schweizer AGITE Software Zurich . West Palm Beach .

Re: [Veritas-bu] Netbackup benchmark performance tuning
Hi Vijay Waited for full buffers messages during a backup means that the tape is able to write more data than bpbkar is able to send. In this example the 11254 delays indicates, that the backup would finish 11254 * 30 msec = 338 seconds faster under optimum conditions. Of course it is very important to know how much data you've backed up during this attempt to find out if this number is extremely high or not. But anyway: it indicates that the filesystem can not be read as fast as the data can be written to tape. A question to your performance test using bpbkar: What path are you using as filesystem? If you are using the device path (e.g. /dev/dsk/c1t0d0s5) you are reading the raw disk. Only if your using the mountpoint (e.g. /usr) you are reading the filesystem. Depending on the fragmentation of a disk the differences in performance are just huge. For me the number you measured (170 MB/s) seems to be very (actually VERY) high for filesystem backup, so probably you're backing up raw disk data or the measured performance was affected by read cache or somewhat else. For me the 22 MB/s looks much more realistic than the 170 MB/s. For FS backup in general and non-RAID OS disk in special I think 22 MB/s is just average and I'm not sure it there is much tuning on this. I would focus on a tuning configuration parameters including MPX. Cheers Ueli Schweizer AGITE Software AG . Boesch 43 . CH-6331 Huenenberg . Switzerland Direct: +41 79 204 9190 .

See point #2 below. You want three things: 1. NetBackup 6.0 Performance Tuning Guide 2. Follow the guide to determine where the bottlenecks are--there's no point in tuning NetBackup buffers if, say, the client can't supply data fast enough. 3. When you can demonstrate to yourself that NetBackup is the slow link in the chain, then it is worth a controlled, rigorous buffer tuning exercise. 128 256KB buffers is way more than enough to drive an LTO2. Don't pick lemons. See all the new 2007 cars at Yahoo! Autos. http://autos.yahoo.com/new_cars.html ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http
Re: [Veritas-bu] Netbackup benchmark performance tuning
Hi Vijay If your FS can be read with maximum 30 MB/s then, because of possible shoe-shining, a backup throughput of 22 MB/s is more or less what I would expect. There are not many options to improve the performance of this single backup. I would try to multiplex the backup with other backups so the tape drive will not come into shoe shining. This will probably improve the performance a little bit, but it is in any case healthier for your hardware (tape drives and tapes hate show shining). Buffer tuning may help a bit, but as mentioned by Bob: 128 x 256 KB is usually ways enough for LTO2 so I don't expect this will change a lot. Cheers Ueli Schweizer AGITE Software AG . Boesch 43 .

So I rebooted and chekced again but same througput. Again I executed same command that time I got more than 150Mbps through put but I think it took the data from memory. So from this I can say I am getting Disk I/o around 30Mbps And about logs Yes it is showing BPTM is waiting for data from the source. For this what changes are required. Thanks regards, Vijay --- Ueli Schweizer [EMAIL PROTECTED] wrote: Hi Vijay Waited for full buffers messages during a backup means that the tape is able to write more data than bpbkar is able to send. In this example the 11254 delays indicates, that the backup would finish 11254 * 30 msec = 338 seconds faster under optimum conditions. Of course it is very important to know how much data you've backed up during this attempt to find out if this number is extremely high or not. But anyway: it indicates that the filesystem can not be read as fast as the data can be written to tape. A question to your performance test using bpbkar: What path are you using as filesystem? If you are using the device path (e.g. /dev/dsk/c1t0d0s5) you are reading the raw disk. Only if your using the mountpoint (e.g. /usr) you are reading the filesystem. Depending on the fragmentation of a disk the differences in performance are just huge. For me the number you measured (170 MB/s) seems to be very (actually VERY) high for filesystem backup, so probably you're backing up raw disk data or the measured performance was affected by read cache or somewhat else. For me the 22 MB/s looks much more realistic than the 170 MB/s. For FS backup in general and non-RAID OS disk in special I think 22 MB/s is just average and I'm not sure it there is much tuning on this. I would focus on a tuning configuration parameters including MPX. Cheers Ueli Schweizer AGITE Software AG . Boesch 43 . CH-6331 Huenenberg . Switzerland Direct: +41 79 204 9190 .

Re: [Veritas-bu] Non-zero exit status on bpstart_notify help
Hi Jason In Windows environments NetBackup does not use the exit code but interprets the content of an ASCII file as the exit code of the bpstart_notify. The name of the file is passed to the script as parameter 6. You should do an echo 14 %6 instead of an exit 14 in your script. Cheers Ueli Schweizer AGITE Software AG . Boesch 43 .
