Transcript

  • 1. Progressive Deduplication & Off site Protection of VMWare Data “Hybrid Cloud Backup” Philippe Guyard Arkeia Software
  • 2. Agenda • Causes of Data Loss • vmOneStep = vmWare dedicated Backup solution • Strategies for Data Protection • Hybrid Cloud Backup/Restore • Progressive Deduplication • Conclusion© 2012 Arkeia Software. All rights reserved. Page 2
  • 3. Causes of Data Loss Source: Kroll Ontrack Inc., 2011© 2012 Arkeia Software. All rights reserved. Page 3
  • 4. vmOneStep Vmware Best fit Backup Solution Console ESX Servers Media Server With Tape Library vmOneStep Virtual Appliance Dedicated Storage ► vmOneStep main points – vmOneStep is a virtual Appliance – Agentless solution: vStorage agent installed in the Appliance F/W – Backup all your VMs without installing a single agent into your VMs – Backup full and incremental done at block level (CBT) – Restore of the complete VM or at file level (Windows & Linux) – Support Lan free backup and restore (if using a SAN) – Support for tape Backup and physical server Backup© 2012 Arkeia Software, All rights reserved.

  • 6. Data Protection Strategy #1: Replication of storage ► Replication – Additional copy of current data (files, images, objects) ► Replication Options – Disk (or RAID) – Synchronous • Expensive: data replicated before transaction completes – Asynchronous • Less expensive: data replication lags behind ► Replication Benefits – Offsite data storage – Immediate failover© 2012 Arkeia Software. All rights reserved. Page 6
  • 7. Data Protection Strategy #2: Backup ► Backup – Multiple Point-in-time “Restore Points” ► Backup Options – Tape, Disk or Cloud – Hourly, Daily, Weekly, Monthly, Quarterly, Yearly – Dedupe data source side ► Backup Benefits – Recovery to time in the past – Offsite data storage© 2012 Arkeia Software. All rights reserved. Page 7
  • 8. Externalization Strategy ? ► Tapes on trucks Backup – Cheapest for large volumes Agent Backup Backup – Scalable Agent Server Backup – Awkward with Dedupe Agent ► Direct to cloud Backup Agent – Simple Backup Backup Agent Server – Slow backup Backup Agent – Slow recovery ► Hybrid cloud Backup Agent – Faster than direct Backup Agent Backup Server Backup Server – Scales better than direct Backup Agent – Flexible© 2012 Arkeia Software. All rights reserved. Page 8
  • 9. “Hybrid” Cloud Backup► Perform backup on LAN – Fast backups, fast restores► Replicate backups to cloud for safe-keeping – First full backup copy made with portable media (Seeding) – Second full backup or incremental with WAN connection Step 1 Step 2 Backup Agent Backup Backup Agent Server Step 2 Backup Agent© 2012 Arkeia Software. All rights reserved. Page 9
  • 10. “Hybrid” Cloud Backup limits ► Full Backup – If time < one week: Over the WAN – If time > one week: Via portable media ► Daily Incremental Backup – If time < 24 hours: Over the WAN – If time > 24 hours: Impossible Backup Agent Backup Backup Agent Server Backup Agent© 2012 Arkeia Software.

  • 12. 1. Arkeia Cloud Seeding and Feeding ► Physical media complements internet transport – 10TB via overnight = 1Gb/s – “Seed” & “Feed” ► Freely mix internet and physical media transport – Transfers may arrive in any order – AES-256 encryption ► Deduped transport – Backup Replication – Recovery© 2012 Arkeia Software.

  • 14. Cloud Recovery Strategies Backup Agent Backup Backup Agent Server Backup Agent ► Data are Secure – Deduplicated – Compressed – Encrypted ► How to Recover/Extract?© 2012 Arkeia Software. All rights reserved. Page 14
  • 15. Cloud Recovery Strategies ► How to Recover/Extract? – Restore (via local LAN) to servers in cloud – Restore (via portable media) to new location Backup Agent Backup Backup Backup Agent Server Server Backup Agent© 2012 Arkeia Software. All rights reserved. Page 15
  • 16. Hybrid Cloud Backup Summary ► Alternative to Tape ► Imposed by incremental backup size ► Primary Cost of Hybrid Cloud – Bandwidth – Target Disk & Replication server ► Pay Attention to Recovery Strategy – Recovery on Portable Media for big amount of data – Recovery via WAN for file level restore© 2012 Arkeia Software.

  • 19. Progressive Deduplication New ► Deduplication Process Sliding window – File content analyses – Bloc size definition Sliding window – Use of “progressive matching” to eliminate duplicate blocs New Sliding window – Use of hash-code to compare with the File known blocs hash-codes ► Source side Backup Process New Sliding window – Deduplication process run on client – New blocs are compressed New – New blocs are sent to Backup server New – For Known Blocs only a pointer is sent to Backup server New Sliding window© 2012 Arkeia Software, All rights reserved.
