However, they each have their own characteristics and have their own strengths and weaknesses.

1 Overview

These five main backup products can be divided into two categories, one is third-party backup software, such as Quest,Veritas,Legato, and the other is backup solutions provided by host manufacturers, such as IBM,HP.

The characteristics of the backup software provided by host manufacturers are: to serve the overall solution of host manufacturers, the products are produced in order to provide integrated solutions, which are often bundled with other products produced by themselves and sold in bundles with their own manufacturers' hosts and tape libraries. Weak compatibility testing for other manufacturers is not the foundation for survival, only need to support their own integrated solution. Other third parties only pay attention to the backup software, which is often used as a subsidiary of other products. The characteristics of the third-party backup software are: it does not have its own host and database, nor does it have its own tape library, and it pays more attention to the compatibility of products. It has extensive support for various platform databases. It attaches great importance to and pays attention to hosts, databases and backup devices of various platforms. Compatibility is the basis of its survival. Compatibility of various operating systems, databases and backup devices is very comprehensive. There is no serious tendency for quality and performance to be better than the backup software provided by the host manufacturer. 2 macroscopic characteristics of mainstream professional backup software

Characteristics of Legato

The data backup software that first entered China (1997) was the earliest enterprise data backup software company that operated on the market. The style of the enterprise data backup software company is relatively stable, and the market image of the company is weak. After it was acquired by EMC in 2003, the operation did not play the role of a big company. On the contrary, because the hardware and software were jointly responsible for sales, sales tended to attach importance to hardware sales and ignore software sales, resulting in insufficient support. Products are relatively large and complex, including highly available software, data backup, data migration software, installation CD 16 localization is poor, there is almost no Chinese version, only the Solaris platform with localized products to use is more complex, need to be very skilled to use before you can adapt, man-machine design operation is more complex, database backup and recovery requires manual scripting, especially recovery, need to modify the script.

Characteristics of Veritas

The companies with the most successful market activities in China are large in scale, mainly relying on network security, file system, volume management, utility computing, data protection, backup products also include low-end Backup Exec and enterprise NetBackup, so, because of the diversity of products, the company is large, the market image for enterprise backup products is not large, only NetBackup backup software, but because of the reputation of the whole company Lead people to think that Veritas backup software is the only first-class wrong impression that the company's backup products are more complex, and need a lot of learning to master backup products, including AIX and HP-UX system disaster recovery, but lack of stability, especially the system disaster recovery under Windows. Patches are often issued due to product problems, which brings a lot of work to technical support.

Characteristics of Quest
