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

BACKUP

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

► Data are Secure– Deduplicated

– Compressed

– Encrypted

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 Index



► 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
