Sap On Esx Backup Methodology Presentation Transcript

  • 1. SAP on ESX – Backup Methodology M. Daniels December 8th 2009
  • 2. SAP on ESX: Backup Challenges What is the impact for backup is SAP runs virtualized? » Considerations: » Off Site Backup » Predictable backup and restore times » Offloading CPU and network » Enable homogeneous system copies » Cost-effectiveness » SAP DB Classifications: » Small <250GB » Medium >250GB < 1,5TB » Huge >1,5TB » Context » A service provider with shared storage, backup, compute and SAP services. 2 MaartenDaniels@Gmail.com
  • 3. Option 1 – Network Backup High Lights Limitations Considerations  BR Backup integrated with Networker or  Network Bandwidth  Off Site Backup Commvault  Predictable backup and restore times  CPU  Offloading CPU and network  Data transfer via network to back-up server offsite  Enable homogeneous system copies  Cost-effectiveness  Small SAP Instances Data files and Redo SAP DB Backup SAP AS Client OS OS SAP DB SAP AS Off site ESX Virtual Machine VMWARE File Systems Cost Drivers  GB on Tape  #Sap Instances 3 MaartenDaniels@Gmail.com
  • 4. Option 2 – VCB Scripted Backup High Lights Limitations Considerations  BR Backup integrated with Networker or  Off Site Backup Commvault via VCB.  Maintainability and ownership  Predictable backup and restore times  Offloading CPU and network  Customized and complex backup scripting. (Ownership SAP admin) Redo Log (network)  Enable homogeneous system copies  Cost-effectiveness  Shift in responsibilities (RACI) SAP DB Backup SAP AS  Data transfer via SAN for datafiles Client OS OS  1 VCB Server per ESX farm. SAP DB SAP AS ESX Mount SAN Snapshot SAP Backup script VCB server VMWARE SAN Backup Datafiles VMFS Filesystem Cost Drivers  GB on Tape  VCB Server  Software  Off site  Time for Script #SAP Instances 4 MaartenDaniels@Gmail.com
  • 5. Option 3 – Self Service Backup via SAN RDM High Lights Limitations Considerations  Simular to Oracle RAC with ASM  CPU Bottleneck on ESX  Off Site Backup appraoch. Assigned datastore for  Predictable backup and restore times datafiles and redo. DBA can organize  RDM limitations on ESX  Offloading CPU and network and is responsible.  Enable homogeneous system copies  Remote SAN storage (SOD – Storage BR Backup Tooling  Cost-effectiveness on Demand) via Raw Device Mapping Self Service Backup Restore (RDM) SAP DB Backup Backup SAP AS Client Store  Full control with BR-Backup OS OS  Paradigm Shift ESX Storage via raw device mapping  Data transfer via SAN for datafiles Virtual Machine VMWARE File Systems Off site Cost Drivers  SOD – AC GB’s SOD – Low Cost SATA SOD Business Class 5 MaartenDaniels@Gmail.com
  • 6. Option 4 – Self Service Backup via NAS High Lights Limitations Considerations  Simular to Oracle RAC with ASM  CPU Bottleneck on ESX  Off Site Backup appraoch. Assigned datastore for  Predictable backup and restore times datafiles and redo. DBA can organize  RDM limitations on ESX  Offloading CPU and network and is responsible.  Enable homogeneous system copies  NAS storage NFS ( FileStorage On BR Backup Tooling  Cost-effectiveness Demand - FSOD) Self Service Backup Restore SAP DB  Off-Site Copy using NDMP Volume Backup Backup Any other SAP AS Dumps Client Store VM OS OS OS  Full control for SAP with BR-Backup NDMP SAN ESX FSOD via NFS  Data transfer stays inside one bubble at one location. Off site Virtual Machine VMWARE  Paradigm Shift File Systems FSOD  Self Service enhancements with snapshots, deduplication Share SnapShots.1.2.3.4.5.6.7 Cost Drivers Self Service ASIS Dedupe Low Cost SATA  GB on Tape  NAS share can be exported to various  GB on SAN or NAS VM’s for homogenious system copies SOD Business Class (dedup) 6 MaartenDaniels@Gmail.com
  • 7. Option 5 – Powersnap High Lights Limitations Considerations  Over 1.x TB use this; don’t bother with  Complexity of Setup  Off Site Backup VMWARE.  Predictable backup and restore times  Offloading CPU and network  Cerfitied on EMC and Networker  Enable homogeneous system copies  Always full Clone  Cost-effectiveness  High End Solution. Cost Drivers  Servers to connect  GB R1 / R2 BCV  Servers to Backup  GB on Tape  CBS Powersnap  CBS SAN Connection 7 MaartenDaniels@Gmail.com
  • 8. SAP on ESX: Backup Challenges » Fit to functional requirements » Organisation » Least time to implement 8 MaartenDaniels@Gmail.com
  • 9. SAP on ESX: Backup Challenges » Netwerk backup has limitation with regards to volume, duration and network bottleneck. » VCB backup is possible, requires custom scripting. Unclear on how to script it application aware. » Raw Device Mapping. (Identical to Oracle RAC setup with ASM). Pardigm Shift. Homogeneous system copy to be validated. » NAS self service infrastructure. » Powersnap / SRDF; not for Virtualized environments. » Other options: Use RAC database on dedicated hardware met SAN backup. Challenge here is to share among customers and the required base load for to leverage cost. 9 MaartenDaniels@Gmail.com
