  1. Fitting SharePoint Into Your Organization’s Disaster Recovery Plans Randy Williams, MVP MOSS Synergy Corporate Technologies rwilliams@synergyonline.com

  2. Session Overview • Recovery overview • Backup options • Web export • Site collection backup • Farm backup • SQL database backup • Third party products • Other items to backup • Recommendations

  3. But first…a little humor

  4. Operations Planning • Ensure alignment between DR and business continuity plan (BCP) • Define recovery objectives (RTO/RPO) • Diminishing returns cost curve UPTIME % COST ($)

  5. Content vs Disaster Recovery • Content Recovery • Restoring individual files or lists/libraries • Rely on versioning, recycle bin • Disaster Recovery • OMG! • A critical SharePoint service/resource is unavailable • Rely on various forms of backup

  6. A Few Points on Recycle Bin • Files aged from first do not go to second • Age setting applies to both bins • Turning off at web app will empty both bins • Only first bin is part of your quota • Web deletion does not go into bin

  7. Backup Choices for Content • Web (export/import) • Site collection • Farm • SQL Server content databases • Third Party

  8. Web Backup • Use stsadm –o export to backup • Also captures sub webs • Not full fidelity • Can use SPD to backup • 24MB limit creates issues • Avoid on large sites/webs

  9. Export Demo

  10. Web Restore • Use stsadm –o import to restore • Will create web(s) or merge into existing • For merge, webs must have same base site definition • Content is recreated • Original created values are lost

  11. Site Collection Backup • Use stsadm –o backup • Serialized into a single file • Full-fidelity backup of whole site collection • Scheduled with task scheduler • Easily list sites with stsadm –o enumsites • Microsoft IT Site Delete Capture

  12. Site Collection Restore • Use stsadm –o restore • Can create or overwrite existing site • If restoring a duplicate site • Must restore into a different content db • Must restore into farm with same SharePoint build

  13. Major SharePoint Build Numbers

  14. Site Collection Restore • If restoring to different path in same web application • File not found error with publishing sites • See http://tinyurl.com/bwazun

  15. Site Collection Restore Demo

  16. Farm Backup • Use stsadm –o backup –directory • Supports full or differential • Does SQL-based database backups • Truncates the transaction log • Only supported way to backup SP indexes • Backup is done to UNC path • SQL Service account and account running backup must have write permissions

  17. Farm Backup • Can back up whole farm or certain items • Web application, content db, SSP, et al • Can be issued (but not scheduled) using central admin • Maintain your backup sets • Make sure you keep spbrtoc.xml in sync • Use PowerShellscript

  18. Farm Backup Demo

  19. Additional Items to Backup • IIS • IIS6 use iisback.vbs; IIS7 use appcmd.exe • SSL certificates • 12 Hive • Easy to zip up • Web App files in wss\VirtualDirectories • Other third party tools (e.g. IFilters)

  20. Farm Restore • Only needed if farm is lost • Must create a new farm with same build • Use stsadm –o restore –directory or central admin • Spbackup.xml lists backup items • Keep content and indexes in sync • Must recreate AAM, certain IIS settings, 12 hive changes, web.config changes

  21. SQL Server Backup • Common to also backup config and content databases through SQL Server • Supports full, differential and incremental • At the VERY least, backup your content databases • Easily scheduled using agents • Also backup system databases (master, msdb)

  22. SQL Backup & Restore Demo

  23. Third Party Backup Solutions • AvePoint’sDocAve • CommVault • Neverfail • Quest’s Recovery Manager • Microsoft’s Data Protection Manager

  24. Data Protection Manager • Part of System Center • Provides comprehensive protection of your farm • Farm, WFE system state • Farm, Site and Item Recovery • SP1 improvements • Catalog performance gains • Index support

  25. Recommendations • Keep a SharePoint change log • Use SharePoint WSP solutions • Actually do trial restores • Use a staging/test farm to perform restores • Keep content db’s small (< 100-200 GB) • Appropriately name content db’s • Do a backup before and after an upgrade • No one solution is best for all

  26. In Conclusion • SQL backups yield the best performance • site/web export is the worst • Third party solutions address • Integration with existing backups • Item, list or library level recovery • Large content stores (>200GB) • High availability Options
