[Veritas-bu] Restore hanging
Dear All we are runnung netbackup enterprise server 5.1 with L100 tape library . restore is hanging it is almost 10 hour but no move forward . library have free drives availble for restore . can someone face this kind of issue here are messages from the logs.

[Veritas-bu] license question re NDMP backup
Hi All Im figure Im more likely to get the correct answer here then from veritas/semantic. I have a netapp filter (a cluster actually) that I currently backup using ndmp to the tape library attached to the (windows) master server. One of the drives is configured as an ndmp drive. The need to have one drive configured as ndmp is kill us and I believe from info on this group that this is still not resolved with netbackup 6 and netapp. So I need another soln. If I was to directly attach a tape library to one of the netapp filer heads, would netbackup be able to control the library? Would i need another licenses beside the license for another library based drive? thanks BB -- Bevan Broun Systems Engineer THALES Services Division W: (02) 9562 2861 M: 0407 225 492 F: (02) 9562 2857 DISCLAIMER:--- This Email may contain confidential and/or privileged information and is intended solely for the addressee(s) named.

Re: [Veritas-bu] Storage and Performance HP & Veritas Net Backup
On 7/1/06, Giblin Dean L. <[EMAIL PROTECTED]> wrote: Backup Performance – The 8GB/Min Goal < roughly 140MB/sec, continuous for 8 hrs > Our future storage space requirements were estimated to be 4 TB. Our requirement is to complete the backups within an 8 hour window. To meet this objective required a backup solution that could provide an 8 GB/Min solution. Hardware: DL580 G3 , Dual Processor, 4GB, LSI 320 to tape, HP RAID controller MSA30 DB , 14x 15K, 146 GB MSL6030, Dual LTO 3 ·HP SCSI drivers for Microsoft Windows have a 64K block size limitation. All the test tools which could bypass this driver and set communication parameters on the SCSI bus obtained increased performance. All of the applications which utilized the system driver suffered. Supposedly there are Veritas drivers for windows that are faster. See previous discussions. Our original design was to implement a RAID 10 solution using two 7 disk RAID 0 arrays. This results in 490 GB of storage and approximately 1.8 GB/min data rate. A 7x 146 GB RAID 5 array should EASILY give you 100MB/sec read performance. Probably much better. The key to speed in NetBackup is SEPARATE I/O CHANNELS! There is a great performance document (which I can't find right now) that shows how Oracle, Sun and Veritas demonstrated a 1TB/hr setup several years ago. Using 2 separate U320 SCSI channels you should be able to have both halves of the MSA30-DB spitting out 100MB/sec or more. Each LTO-3 tape drive needs its own U320 SCSI channel. (The robotics can piggyback on one of those channels.) The system disks in the server itself need a separate SCSI channel as well. That brings us to a total of 5 separate high-speed SCSI channels. If you don't currently have 5 separate channels, you need to add some of these: http://lsi.com/products/scsi_hbas/lsiu320.html The other side of the equation is the network performance. To backup a NAS box over the network you need to optimize the network path. Jumbo frames will probably help. Aggregating 2 gigabit ports might help too. You didn't say how many other clients will be backing up over the network. If there are many clients, spread them across multiple gigabit interfaces on the server. To keep the LTO-3 drives happy, you need to feed them at least 40 MB/sec. To meet your design goal of 8 GB/min you need to continuously feed 2 drives @ 70 MB/sec each. That will be fairly difficult and will probably require 4 separate gigabit interfaces. I suggest adding one of these to the two built-in NICs: http://intel.com/network/connectivity/products/pro1000mt_dual_server_adapter.htm The difficulty lies in having the clients produce data that fast. You will most likely need to have the client data streams multiplexed @ 4 or 8 streams per tape drive. Disk staging is useful for slow clients, but is probably a negative factor for the NAS box. Here's my summary: - Add I/O channels for a total of 4 gigabit Ethernet and 5 U320 SCSI channels. - Optimize the network between the NAS box and the backup server. - Send the NAS data directly to a single tape drive. - Configure 1 LTO-3 tape drive per SCSI channel - Configure 1 RAID5 array per SCSI channel - Separate the system disks from the backup SCSI channels - Use a High MPX on client backups to tape. - Use disk staging only for VERY slow clients. - Use the Vertias drivers where available, not Microsoft or HP. You need to be able to read or write at over 100 MB/sec on each SCSI channel and you will need to read from the network at over 50MB/sec on each Gigabit interface ALL AT THE SAME TIME. With a Solid PCI-X backplane (like the DL 580G3 has) this is entirely reasonable.
