NBU 5220 Performance
We recently deployed a 5220 appliance into our environment as it was to be the savior in our battle against a backup window we were no longer able to meet. When we finally got it online and into our NBU environment the initial performance was great. The area we were to most benefit was with VMware backups. The data stores mounted directly to the appliance would allow direct access to the snapshots for a fast and efficient backup. Before this, we were performing client side backups so the impact on the hosts every night was significant as we tried backing up 600+ vms. The plan was to be able to move all Dev and test off-host backups to the middle of the day as the performance impact was minimal and the end result was an increased window to complete things. As we started with noon-time backups deduplication rates were high and so were the speeds. However, this performance gain was short lived, as we began increasing the load we suddenly saw performance drop to a point of concern. Backups were no longer speedy, 3500KB per second to 10,000KB. There are some that might pop to 24,000KB, but in a sample size of 15 as I write this, only one is showing 24,000. Now, I do have a few ideas. 1. We have a 72TB appliance, therefore, 2 disk trays, during the backups, the one disk tray is going crazy, all the lights are flashing and you can really see that it is working. However, the second tray is doing nothing. While you might see a blink here or there, it is almost nothing compared to the other disk tray. Is this to be expected? When we looked at the disk configuration, it shows concat, is this normal? 2. Too much data at once and we are simply burying the appliance. In reality, what sort of performance should I be able to expect from the appliance? 3. Relating to number 2, since we only have the one appliance right now while we wait to get the remote appliance in place, we are duping off to tape. This is running at the same time as a backup, so this means at the same time the appliance is writing a lot of data, it is also reading it back to tape. 4. We are overloading the data store so that read speed is bad from source to destination. We have fewer hosts,therefore, if we limit the jobs per host we limit the number of machines backing up at once (obviously). This means that backups take way long, so we removed the limit per host and just set a limit per data store. As we are new to it all, I am not sure what impact where, but again, I am trying to list any and all ideas from the start. 5. The appliance does not support multi-pathing, therefore, we only have a single path to the disk. Beyond that I am not sure, but this is something that doesnt help with the showcasing of the appliances to management at the moment. However, given the initial performance I am confident we can get back there.Solved3.2KViews4likes50Comments
duplications from wrong media server
I have two 5200 appliances (2.0.1) one is in our primary data center and one is at our DR site connected by a 43mb pipe. My primary appliance has two LTO tape libraries directly attachedvia fiber that are used for doing monthly backups. I am using SLP's for the back up and duplications. Every weekend we do a full backup (1.3tb)that is backed up to my primary appliance and then duplicated to my DR appliance.During this backup i notice that my media server that is being used is primary > primary (for backup) and DR > DR (for duplications). This is perfectly fine. Now heres the trouble. When i mix a duplication to tape in this process the system trys to load balance the duplication between my media servers. Meaning: One duplication job will show the primary as the media server for the tape backup and one job will show the DR appliance. This would all be ok if the DR appliance was on my local LAN but it is not and therefore any duplication using it as the media server to tape can take over 24 hours to complete. In the SLP for my monthlys I have removed the DR appliance as a duplication so i dont know why it keeps responding. Example: i had a 245gb exchange DB duplication thatwas usingmy DR appliance as the media server and it had been running for 48hours and was only 60% complete. I noticed the job and cancled it. When it retried it picked up my primary appliance as themedia server and in25min it was complete(over fiber channel). I opened a ticket with support 2 months ago but we have yet to figure out the deal. This hasnt been that big of an issue until another group wanted to replicate some VTL's to the DR and realized that the bandwith is 100% consumed all the time by netbackup. i have been tinkering with this for months and cannot figure out what i have configured wrong so i want to consult the almight Community for answers. LOL! To me it sounds like the media servers are setup so that they can load balance but i cant find were to disable that.Solved1.9KViews4likes6Comments
NetBackup Appliance 5230 as Master Server
Hello there!! Does anybody know if I can upgrade a NetBackup Appliance 5230 configured as master server from 2.6.1 to 2.7.1? Or if I can have a NetBackup Appliance 5230 configured as master server with version 2.7.1? I try to find the information in SORT, but I don't realle understand if a 5230 master server can have 2.7.1 or not: "NetBackup 5200 Series Appliances running 2.x or later can be used as back-level media servers in a NetBackup 7.7.x configuration. NetBackup Appliance and NetBackup versions will resynchronize in future releases." And one more question, does anybody know how can I determine if I need to use a 4 Tb or a 14 Tb master server? Thanks!!Solved2.4KViews1like3CommentsNFS mount point on NetBackup 5230 Appliance
Hi Team, Please I need your expert advise on this solution: Customer has proposed implementing backup solution via NFS; this solution is based on having the centralized server IPs & file path where to send the backups to. We currently have Symantec NetBackup 5230 Appliance installed in this customer datacenter. Question: Will NetBackup 5230 Appliance support mount points from network file systems (NFS). This will enable customer backup their network file system data to the central storage location, which is on the NBU appliance.

Hi Support, Kindly advice me because I'm a bit confused. I am about to configure AIR between two NetBackup domains, domainA has 1xNBU5230 plus 1x5030 disk shelf, anddomainBhas 1xNBU5230 plus 1x5030 disk shelf. Also both NetBackup domain will be backing up clients seperately, however customer still wants image-data replicated to the target or secondary domain. My question is how can I then configure AIR btw these domains, since each NBU domain isbacking upclients data tothe MSDP pool which is suppose to be used for AIR configuration. Thanks in advance, FelixSolved2.5KViews1like7Comments
5230 Appliance - Best Practice for iSCSI SAN backup
As the 52xx Appliances do not support iSCSI attach I am just wondering what is seen as best practice for securing VMware data when the datastores reside on an iSCSI attached SAN. I guess there are two options: 1. Create 1 or more VMware Proxy Backup Servers (Hot-Add) within the ESX environment 2. Install 1 or more physical Proxy Backup Servers (Hot-Add) which have an iSCSI connection to the SAN Are there any more preferable ways to do this, or if not which of the above is best in terms of functionality and performance ? Thanks, AJ.Solved1.8KViews1like5CommentsNetBackup 7.5.0.4 support for vCenter Server 5.1 update 1
I searched for an updated matrix regarding this, but to no avail. My question is this...VMware just released vCenter Server 5.1 Update 1...will our current 7.5.0.4 NetBackup environment support this? We are running on 5220 appliances.Solved781Views1like4CommentsMigrating Images between Netbackup Domains
I have a requirement whereby we are replacing 4 x 50x0 Puredisk Appliances with 4 x 5220 Appliances. The current config has all devices in the same Netbackup domain, even though 2 of the 50x0 appliances are in a remote location. Each pair of 50x0 appliances is presented as a single pool within Netbackup. We are implementing the new 5220 appliances in an AIR configuration - therefore there will be two distinct NBU domains (one production and one DR). The current master server will remain in the production site, with one of the 5220 appliances in DR acting as the Master server in the other NBU domain. My issue is in migrating the data from the current 50x0 appliances to the new 5220 appliances. In the production site the images can simply be duplicated from the 50x0's to the 5220's, as they are all in the same NBU domain. But when considering migrating the images from the remote 50x0's (which are part of the original production NBU domain) to the new 5220's in the new NBU domain - what are the best options here ? The environment does not include any tape devices. AJSolved3.9KViews1like11Comments
Appliances, vmware and multipathing
Hi all I'm seeing a lot of folk buying appliances and finding out that they can't use both of the HBAs with VMware vStorage API because multipathing is not supported on the appliance. Whilst "this may be supported in a future release", I'm wondering what you guys are doing in the meantime to be able to use san transfer method with vmware backups? Does single processessor/port/HBA zoning present a single, usable path for example? Or are you still bound by multiple ports used on the storage processor side? Thanks ChrisSolved828Views1like4Comments5220 Appliances - Buffer Tuning & Throughput
Does anyone have any experience of tuning throughput on a 5220 Appliance ? I note that the data buffers are set to 262144 (standard setting) and there are 30 of them. Are you finding that these require tuning to achieve maximum throughput or are you simply leaving them set to default ? I have a Virtual Master server at 7504 and a single 5220 acting as a media server attached to both SAN (for VMware integration) and a tape library containing 2 x LTO5 drives. I am backing up VMware machinesusing the VMWARE policy type (SAN transport), physical machines using agents over the network and CIFS data using the NDMP policy type. In addition, I am using AIR to replicate to a similar configuration for DR. Before I start tuning I thought I would put this out there to discover what everyone else may have alreadyfound as best practice...... AJSolved1.6KViews1like8Comments
