4 Basic understanding of the entire backup data path is important in determining maximum obtainable performance Poor performance can be the result of unrealistic expectations and / or poor planning Every backup environment has a bottleneck. It may be a very fast bottleneck, but it will determine the maximum performance obtainable with your system // Backup and Recovery Best Practices Session: 3, Track: ELA Services

5 Break down infrastructure into smallest possible segments How can I characterize what Determine exactly where the bottlenecks are in your environment performance my environment Understand is capable the limitations of? your current backup system // Backup and Recovery Best Practices Session: 3, Track: ELA Services

6 NetBackup client Storage to be tested might be anywhere Clients Server (catalogs) Understand capabilities of each component Use the 70% rule to determine throughput Session: 3, Track: ELA Services 6

7 NetBackup client HBA and Connection type (SCSI, FC, iscsi) important considerations: Determine what variety is used to determine throughput FC 2Gb/s, FC 4Gb/s, FC 8Gb/s Use the 70% rule to determine throughput Session: 3, Track: ELA Services 7

8 NetBackup Media server NetBackup client Understand the network infrastructure Many Switches components can cause network throughput issues Firewalls rules DNS 1 GbE issues / 10 GbE Incorrect/outdated network drivers Session: 3, Track: ELA Services 8

9 Many sites are looking to replace tape with disk ATA is a cheap alternative iscsi/nas are additional alternatives Be sure to understand the performance differences What is your site considering? NetBackup Media server Media Server Dedupe Pool // Backup and Recovery Best Practices Session: 3, Track: ELA Services

10 NetBackup client Deduplication Plug-in Meta data Control communication NetBackup Media server Local Disk NOT all data de-duplicates at the same rate Places to de-duplicate: Source Target Appliances Enables advanced features to create a DR copy. PureDisk Pool Media Server Dedupe Pool // Backup and Recovery Best Practices Session: 3, Track: ELA Services 10

11 Additional Considerations for Disk To de-duplicate or not to de-duplicate Disk Fragmentation Anti-Virus settings Block-Size File Compression Disk array configuration RAID type // Backup and Recovery Best Practices Session: 3, Track: ELA Services 11

12 Total Dataset Size: How much data will be backed up? Approximate amount of data change? Data Type: Types of data text, graphics, database How compressible? Number of files? // Backup and Recovery Best Practices Session: 3, Track: ELA Services

13 Step Description 1 Calculate the rate of transfer that Backups must achieve to complete a backup of all your data in the allowed time window. 2 Decide what kind of tape drive technology meets your needs by calculating how long it takes to back up to tape. 3 Calculate how many tape drives are needed. 4 Calculate how long it takes to back up to disk. 5 Calculate how long it takes to move data over the network. 6 Calculate how much disk space is needed to store the catalog. 7 Calculate how many tapes are needed to store and retrieve your backups // Backup and Recovery Best Practices Session: 3, Track: ELA Services 13

14 Baseline versus Performance Test To run a performance test: 1. Check and make sure no other jobs are running 2. Submit the job to run now or manual backup 3. Check for non-backup activity on the server during the perf test 4. Re-check activity monitor for other activity that may have occurred during the test (such as Restore) // Backup and Recovery Best Practices Session: 3, Track: ELA Services 14

15 What Master and Media Servers Should I Buy To Run NetBackup? Master Servers High CPU requirement, lower I/O As a general guideline, a Master should have multiple physical CPU s and lots of RAM Media Servers High I/O - Lower CPU requirement As a general guideline, any Media Server should have PCIExpress BUS 15 Backup and Recovery Best Practices

16 How much disk space is needed on the Master? Assume 120 bytes per backed up file and use 1.5 multiplier for growth and error Example 100 systems with 100,000 files on each backed up FULL daily 100 systems * 100,000 files * 30 backups = 300,000,000 files total 300,000,000 * 120bytes = 36,000,000,000 bytes = 36GB to store this much in the catalog Use this with Retention to determine long term catalog needs with the 1.5 multiplier Use the 2% rule Total data tracked * 2% If you are backing up 3TB of data based on fulls, incrementals, and retention then catalog space needed is 60GB Using a disk manager so Catalog can grow on the fly is very important Typically when catalog hits 1TB it is time to split (or sooner) 16 Backup and Recovery Best Practices

17 Determine if you are using appliance versus traditional If traditional - Generally more RAM is needed for the media server What else is running? NetBackup uses shared memory for local backups Buffer tuning is critical Buffers use shared memory a finite resource To determine how much memory is being used use this formula (buffer_size * number_buffers) * number of drives * MPX Defaults Size = (64 * 1024) Number = Backup and Recovery Best Practices

18 If Appliance Use information from calculations to determine required space and throughput To OST Cloud 1. Remote office backups Integrated tape out 2. Data Center backups NetBackup 5220 Integrated replication NetBackup 5220 ESX 3. VM backups Auto Image Replication for DR readiness Fiber Transport media server support New! Cloud Gateway // Backup and Recovery Best Practices Session: 3, Track: ELA Services 18

19 LAN Clients (target) 1GigE Any or all 1GigE ports can be bonded together to create a larger pipe LAN Clients (source) SAN Clients FC 10GigE 10GigE ports may be bonded together to create a larger pipe NetBackup 5220 Dedupe processing Standard Data Transfer over IP Standard Data Transfer over FC Optimized Transfer over IP 8Gb FC Use when replacing physical/virtual tape libraries with NetBackup appliances Convert application clients configured as SAN media servers to SAN clients, thereby reducing the backup application resource footprint // Backup and Recovery Best Practices Session: 3, Track: ELA Services 19

20 NetBackup Buffers for Disk and Tape SIZE_DATA_BUFFERS_DISK NUMBER_DATA_BUFFERS_DISK SIZE_DATA_BUFFERS NUMBER_DATA_BUFFERS NetBackup Network Buffers NET_BUFFER_SZ These are only a few buffer settings use with care and guidance // Backup and Recovery Best Practices Session: 3, Track: ELA Services 20

23 Determine restore requirements Determine type of applications in the VM s Determine infrastructure Number of virtual machine hosts Number of ESX/Hyper-V systems Determine data flow Network SAN ETC // Backup and Recovery Best Practices Session: 3, Track: ELA Services 23

24 Enhanced Integration with VMware Provide the ability to automatically find and select VM s. Provide the ability to throttle backups based on resources. Enhance existing manual selection to show clusters and vapps. Filters can be based on virtual machine attributes Backup all the machines in Power On state Backup all the machines where OS type is Windows 2008 Backup all the virtual machines for which display name starts with VMprod // Backup and Recovery Best Practices Session: 3, Track: ELA Services 2 4
