The SAN (Storage Area
Network) transfer mode
allows you to transfer
backup and recovery data
through the SAN when the
DS-Client or Remote
DS-VDR are running on a
physical machine and they
have direct access to the
VMware VMFS datastore
through FC/FCoE/iSCSI.

The DS-Client accesses only the changed blocks of the virtual machines.
2
The DS-Client deduplicates, compresses & encrypts the changed block & sends them to the DS-System for storage.
1
The DS-Client runs on a physical machine.
3
The DS-System receives the data from the DS-Client.
2
Using the SAN transport mode, the DS-Client reads data directly from the SAN storage where the .vmdk virtual disks are stored.
4
The DS-System stores the data in the backup repository in compressed, encrypted & deduplicated form.
3
The DS-Client accesses the VMFS data store and obtains the changed blocks of the virtual machines using the VADP and VDDK API.
5
The remote DS-VDR obtains the changed blocks from the DS-System, decrypts, uncompresses & updates the changed blocks of the backed up VMs into their original format.
4
No data is transferred through the ESXi host to DS-Client.
6
The remote DS-VDR performs an incremental restore of the VMs to a standby ESXi server by opening a disk writer & writing the changed blocks to the proper section of the disk to enable
resumption of business operations from this failover infrastructure.
5
The DS-Client deduplicates, compresses and encrypts the virtual machines and sends them to DS-System.
7
When faced with a disaster, users can turn on the backed up virtual machines and access their data running on those virtual machines at the Remote Offsite Data Center via external IP/access.
6
The DS-System stores the backed up virtual machines in the DS-System online storage at the Remote Offsite Data Center.
8
The remote DS-Client backs up the changed blocks of the failed over virtual machine in compressed, encrypted, deduplicated form.
7
The Remote DS-VDR runs on a physical machine and reads the backed up data from the DS-System Online Storage. The Remote DS-VDR decompresses, decrypts and builds the virtual
machine’s disks from the backup data into its native ‘.vmdk’ format.
9
The DS-System stores the data in the backup repository in compressed, encrypted, deduplicated form.

10
At the time of the failback, the remote DS-VDR at the primary site obtains the change blocks from the DS-System in compressed, encrypted, deduplicated form.
The Remote DS-VDR transfers the virtual machine’s disks to the VMware ESXi storage through the SAN using the SAN transport mode. No data is transferred from the Remote DS-VDR to the
ESXi host through the LAN.
11
The remote DS-VDR decrypts, uncompresses & updates the changed blocks of the failover VM into its original format.
9
The virtual machines are now available to be turned on at any time.
12
The remote DS-VDR performs an incremental restore of the VM to the ESXi server to enable the failback of business operations to the original infrastructure.
10
When faced with a disaster, users can turn on the backed up virtual machines and access their data running on those virtual machines at the Remote Offsite Data Center via external IP/access.

The HotAdd Transport
Mode allows you to
transfer backup and
recovery data through
the SAN when the
DS-Client or Remote
DS-VDR are running on
a virtual machine and
they have direct access
to the VMware VMFS
datastore through the
FC/FCoE/iSCSI. This is
only supported when the
virtual machines that are
being backed up are
using SCSI virtual disks.
