► 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

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

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

8. Externalization Strategy ?
► Tapes on trucks

– Cheapest for large volumes

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

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

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

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

► 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

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
