specification should be ${foo}, or the following form can be used, the specification is certainly not wrong.If there is no corresponding reference, the VTL is treated as a normal string.In Velocity Template Language (VTL), there are three types of references: variables, properties, methods.All references are treated as strings, and if a reference is an integer value, velocity calls the ToString () method t

-level deployment. Hardware-based deduplication may also be integrated into other storage (target) platforms. For example, deduplication is often a feature of the VTL system. The VTL system uses disks instead of tapes for storage to speed up backup tasks. In addition, you can add duplicate data deletion to maximize VTL disk usage. In many cases,

Today, users are increasingly familiar with technology and security, and they want suppliers to provide strict data protection while ensuring solid and reliable services. In addition, the customer's mentality is often volatile, and usually will not hesitate to embrace competitors when discovering the security risks of existing

that the disk storage system used for data archiving should not be shut down, and the process of power-back is complex. And in advocating "green computing" today, the long-term boot is not conducive to the reduction of energy consumption. Moreover, for decades, hundreds of years of information, the use of frequency is not necessarily very high, disk and tape, compared to cost-effective more disparity. So, for data archiving, tape libraries are still the best choice to be irreplaceable. For fas

The simplest and easiest way is to use Weave to configure Nginx in a Docker container running on Ubuntu as a load balancer server.1.

and software bring more problems and maintenance costs. So we use Packer and Vagrant to unify the production environment and development environment, Packer build operating system images for Vagrant to run the virtual development environment, so that all developers have a unified and continuously updated development environment, more conducive to reduce problems and collaboration. Packer-built mirrors are also available for large virtualization platforms such as KVM, Xen and ESXi, as well as

As one of the core services of cloud computing, storage services are used by every user. However, the current situation is: most customers in addition to virtual machine data disk (persistent disk), and does not fully utilize the storage services. Let's look at a typical scenario: for example, a Web application needs a user to upload an invoice scan (image file). At the code implementation level, the image files uploaded by the user are usually saved directly to the disk file system. In a tradit
