Data Protection Challenges for Virtualized Servers

3NetApp Confidential - Limited Use

Server consolidation expands volume of data

More applications per server increases business risk

High server utilization reduces spare cycles required for backup

Tape is slow, complex, and expensive

Architected for what we did yesterday


The Value of SnapManager for Virtual Infrastructure

4

Addresses highly dynamic, resource-intensive virtual environments without impacting performance or introducing administrative complexity

Simplifies data protection management

Optimizes resource utilization

Improves RTO and RPO

Leverages NetApp® Snapshot™ and SnapRestore® technologies

Scales with your virtual infrastructure


SMVI Overview

Per-Job Backup Options:

–Triggering of VMware® snapshots for application consistency–Triggering of pre/post backup scripts–Exclusion of selected datastores–Inclusion of independent disks–SnapMirror update–Time-based or number-of-copies–based retention period–Customized alert notification

Other Features:

–Immediate or scheduled application, or crash-consistent backups of VMs or datastores–Flexible recovery at any level of granularity–Updating of existing SnapMirror relationship at backup completion for integrated DR–Mounting of backups for prerestore content verification –Protocol support: FCP, iSCSI, and NFS

SMVI Backup Operation

Primary Site

API

Storage Pool

1. SMVI initiates a backup

2. SMVI triggers VMware®

snapshots of VMs

3. vCenter creates

consistent snapshots of

VMs and captures active

transactions in delta files

4. SMVI triggers instant

NetApp® Snapshot™

5. SMVI triggers VMware

snapshot removal

6. vCenter removes

consistent snapshots and

reapplies the delta files

SMVI 2.0 DetailSFR Workflow

13


SMVI 2.0 DetailSFR Things to Know

Assumptions– A process already exists to initiate a file restore request

Helpdesk Ticket system

– File restore authorization is done outside of SMVI

Terminology– Source VM: VM to which backup is associated and from

which files are copied

– Destination VM: VM to which files are restored (could be same as originating VM)

14


SMVI 2.0 DetailSFR Use Cases Self-service restore

Network connectivity exists between destination VM and SMVI server Requester can browse all backups, select files, and restore them to

any location within active file system

Limited self-service restore No network connectivity between destination VM and SMVI server Administrator mounts disks from selected backups Requester can browse all mounted disks, select files, and restore

them to any location within the active file system

Administrator-assisted restore Company policy prohibits self-service restore Administrator goes through the self-service restore process for the

requester and places files to be restored in an accessible location Requester copies files from accessible location to any location within

the active file system 15


SMVI 2.0 DetailOther Stats

Upgrade/revert – SFR will work with backups created by SMVI 2.x and

later

– SFR will be disabled for backups created by SMVI 1.x

Compatibility– VMware® infrastructure 3.5.x and later

– Data ONTAP® 7.2.3 and later (FAS)

– Data ONTAP 7.2.4 and later (vFiler®)
