Data Protection Challenges for Virtualized
Servers
 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

Simplifies data protection
management
Optimizes resource utilization
Improves RTO and RPO
Leverages NetApp®
Snapshot™ and SnapRestore®
technologies
Scales with your virtual
infrastructure

SMVI Backup Operation

1. SMVI initiates a backup
2. SMVI triggers VMware®
snapshots of VMs
3. vCenter creates

What’s in it for me?
 Solution for day to day backup and recovery
 Back up and restore your VMs
instantaneously.
 Ensure business continuity and protection of
all your virtualized data with DR.

SMVI Single File Recover (SFR)
Can restore one or more
files from a VMDK without
having to restore the
entire VM
Single File
Restore
Three types of restores:
SMVI
Self-service
Limited self-service
Administrator
Requirements:
Data ONTAP® 7.2.3
SMVI 2.0
VMware® ESX 3.5 or later
Restore Agent (RA) is
installed on a guest VM
to browse disks
containing files to be
restored
RA enables Guest OS to
scan for new storage and
mount disks to active file
system

The RA enables the requester to:

Mount a disk from a backup

SFR Workflow
End User
Helpdesk
SMVI
Admin
End User
• I lost some files from my VM
• I believe I had those files last Thursday. Is there any way I can get
back those files?
• OK, I have created a ticket, please wait for an e-mail giving you
instructions on how to restore files
• Receives SFR ticket, enters user & VM information
• SMVI server now allows VM to access its own backup & sends
an e-mail
• End user installs Restore Agent, opens e-mail attachment
• Using Restore Agent, looks for backup, mounts disk and uses
Explorer to copy the files

SMVI 2.0 Detail
SFR 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)

SMVI 2.0 Detail
SFR 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

Other 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®)
