This document discusses a proposed hybrid disaster recovery solution for OpenStack using VMware and object storage. The solution would backup VM disks to object storage like Swift, Amazon S3 or Google Storage for reliable, distributed storage. It would then use the VMware vCloud driver and OpenStack Cinder to restore disks back to VMware datastores. This provides backups across on-premise VMware and public clouds with reliability improvements over traditional backup methods. The proposed vCloudSync product would provide agentless, deduplicated backups to object storage along with migration between VMware and Google Compute Engine.

1. VCLOUDSYNC – HYBRID DISASTER
RECOVERY FOR OPENSTACK
5 Mar 2014
Vinothini Raju,
CloudCamp, Bangalore

2. SCOPE
Backups & Restores across public clouds (AWS & GCE) and private clouds (Openstack
+ VMWare)

3. VMWARE & OPENSTACK CO-OPETITION
Co-operation
1. Openstack using VMWare
2. Complement features - VMWare (live migration, DRS etc) & OpenStack (Object Storage for
backups)
Competition
1. Customers see Openstack as an alternative to VMWare
2. Migrate VMWare environment to a neutral environment

4. CURRENT VMWARE + OPENSTACK INTEGRATION
Grizzly
1. ESX Driver (no vMotion, DRS, HA) , Driver runs in 1 nova instance per ESXi host
2. VC Driver (vMotion, DRS, HA), Driver runs in 1 nova instance per ESXi cluster, abstracts cluster
Havana
1. “Multi-cluster” management, 1 nova instance for multiple ESXi clusters
2. Block storage volumes (Cinder) can be stored as VMDKs as VMFS datastores (Snapshots go to vCenter
datastore).
3. VOVA (VMWare Openstack Virtual Appliance) – packaged OpenStack vApp
Icehouse roadmap
1. Cinder replication across different OpenStack installations
2. VMware Datastore Storage Backend (use image location reference instead of migrating the images)
3. VM diagnostics

6. VMWARE BACKUP & DISASTER RECOVERY - TODAY
1. Consolidate backup
VMDK disks are snapshotted and mounted to backup proxy server and copies made to
backup storage.
2. VMs as physical systems
Backup agent runs inside the VM and backs up data to backup servers or attach iSCSI tape
as media & copy
3. VMs as a file on ESXi
Backup agent runs on the ESXi console & backups the VMDKs as a file to backup server.

7. RELIABILITY & HA ?
Twitter blames two-hour failure on dual data-center crashes.
Rawashdeh, VP, Infrastructure Operations Engineering at Twitter.
called an "infrastructural double whammy.“
Earlier:
• managed hosting services from NTT America
• Amazon’s cloud computing services to store and deploy
images, including profile pictures

Now:
Twitter has setup datacenters to cater to its IT needs

8. WHAT DOES THIS IMPLY ?
1. Distributed environment (not all eggs in one basket)
2. Reliable Backup technology
3. Diverse clouds & infrastructure for backups

9. NEED FOR OBJECT STORE BACKUP
Object Store [1] - Distributed data (3 sites) compared to RAID backups (3 copies +
Tape backup)
1. Capacity: 60% more efficient
2. Cost : 80 – 90 % cost saved
3. Reliability : 100 Million times more reliable
Swift:
 Scalable
 Durable
 In house deployments [no-vendor lockin, cost effective, less latency]

10. PROPOSED SOLUTION
VMWare VCDriver + Object Store for backup
1. Backup vmdks (root, data & snapshots) on to Object Store (Swift/Amazon S3)
2. Restore vmdks to VMWare shared datastore

13. VCLOUDSYNC
vCloudSync
 Backup VMDK to AWS S3 & Google storage (Offline backups)
 Restore VMDK back to VMWare
 Google agent to migrate VMs between VMWare & GCE (Centos & Ubuntu)
Roadmap
 Snapshot backup
 Integration with VCDriver/OpenStack
 AWS agent to migrate VMs between VMWare & AWS (Ubuntu)

14. WHY VCLOUDSYNC ?
+ Agentless backups
+ Optmized for cloud backups and no local backups
+ Optmized Chunk size
+ Multi-part backups
+ Simultaneous backups
+ Deduplication
+ Compression (Ratio - 10:8.9)
+ ~ 20% better upload performance compared to manual uploads
+ Agnostic to virtualization or cloud technologies - Backup As A Service Engine
+ Reliability – meta data based backups
