VMware VDP backup to san storage cannot be read, written and backed up normally.

Protecting enterprise data is an important part of any business continuity plan. Since there are many solutions on the market at present, the key is to find a solution that suits the needs of your enterprise. As early as August 20 12, VMware and EMC reached a partnership and introduced the data protection (VDP) technology of vSphere to the market. The VDP is released together with vSphere 5. 1 and is built into vsphere 5.1essentials plus and later. That's good. If you have vSphere 5. 1, you can already use VDP for free. There is also an advanced version of VDP, which contains all the functions and features of VDP and is suitable for a larger-scale environment, as well as application agents of Microsoft SQL Server and Microsoft Exchange. These agents contribute to consistent backup of applications and more detailed backup and recovery functions.

VDP takes full advantage of EMC Avamar's code to provide enterprise-class stability and deduplication through a backup solution specifically designed for small and medium-sized environments. VDP uses patented variable-length deduplication algorithm, which can achieve more than 90% efficiency. For example, I backed up 100GB virtual machine in the lab environment, but these backup data only consumed 9.8GB of actual storage space on VDP hardware devices.

Advantages of VDP include:

Can quickly and efficiently back up and restore VMware virtual machines;

For all backup tasks, the patented variable-length deduplication technology is used uniformly, which greatly reduces the demand for disk space for backup data;

VMware vSphere API(VADP) and Changed Block Tracking (CBT) for data protection can be used to reduce the burden on the vSphere host infrastructure and minimize the backup window requirements;

The whole virtual machine recovery (or "image-level" recovery) and file-level recovery (FLR) can be realized without installing an agent in each virtual machine;

Using virtual device format parameters simplifies deployment and configuration;

You can use the vSphere Web client program for management.

Checkpoints and rollback mechanisms can be used to protect devices and data;

With the VDP recovery client based on Web, end users can easily recover Windows files and Linux files.
