vmOneStep Vmware Best fit Backup Solution
► 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. Page 4

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

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

Externalization Strategy ?
► Tapes on trucks
– Cheapest for large volumes
– Scalable
– Awkward with Dedupe
► Direct to cloud
– Simple
– Slow backup
– Slow recovery
► Hybrid cloud
– Faster than direct
– Scales better than direct
– Flexible

“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

“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

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

Cloud Recovery Strategies
► How to Recover/Extract?– Restore (via local LAN) to servers in cloud
– Restore (via portable media) to new location

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
– File content analyses
– Bloc size definition
– Use of “progressive matching” to eliminate duplicate blocs
– Use of hash-code to compare with the known blocs hash-codes
► Source side Backup Process
– Deduplication process run on client
– New blocs are compressed
– New blocs are sent to Backup server
– For Known Blocs only a pointer is sent to Backup server
