Tape drives – a solution for creating redundant copies of data that are suitable for the separate computers, and large computing centers. The advantage of tape drives is the optimal price / performance ratio (the cost of storing information units minimum). Storage Technology on the tape is very fast read and write information that allows for the rapid exercise of the backup process, not stopping the computer center. Louis Monier is actively involved in the matter. Most convenient to use tape libraries and tape drives. For example, a very popular tape libraries, HP. Using RAID, available in servers and enabling rapidly recover data in case of trouble, is not a reliable way to backup. System redundancy RAID helps mostly snivelirovat hardware failures. Wrong rely solely on the use of RAID, as in the case of 'human' errors (eg incorrect operator actions or accountant), the system will not allow to roll back to the time of the error and restore the correct data.
Tape libraries also allow you to store much more information. And she kept on tape cassettes for much longer than hard drives. Such data carriers are not afraid to shock, is resistant to electromagnetic interference and temperature changes, and do not be afraid of many other natural factors. Leaders in the market – Tape Drives HP. Largely due to the interesting price and sales leadership in backup systems.
And users prefer to buy the cartridges from the same manufacturer that bought a tape drive. Function One Button Disaster Recovery (OBDR), created based on the software allows you to restore data in case of accidents with one click. The technology used in OBDR saving data to tape, with the tape drive is bootable, registered in the server's BIOS as CD-ROM. Since the cartridge is loaded the operating system with latest patches, which was correct at the time conservation. An automatic full restoration of the operating system, and then the data. Thus, the technology OBDR gives an opportunity to restore the server for several minutes even for an expert with minimal knowledge of technology. To date, there is a huge choice of backup systems. Basically this tape, using a consistent data organization, and disk drives, providing random access to stored information. Choosing a system for their organization, should take into account such factors as the type of backup and recovery, speed, maximum capacity carrier and the volume of the device as a whole, the cost of equipment and cost of its operation, reliability, etc.
