What is D2D?

D2D, or disk-to-print is an efficient and excellent backup strategy that uses hard drives as a storage medium, rather than traditional tape media systems.

As the price of hard drives is falling, while capacity and speed are still increasing, the use of other D2D backups has become a proverbial without conviction for individuals and companies interested in protecting their computer systems. The arrival of RAID (redundant series of independent disks) also contributed to the D2D backup strategies. Motherboards that support advanced RAID varieties use multiple disks in different ways to increase speed, provide redundancy and offer error correction. In the Raid and Non-Raid environment, D2D backup has several advantages above the tape or optical storage.

There are two types of D2D: True D2D and virtual cassette library or VTL D2D. It is not true D2D because it maintains a file index similar to tape. Although fasterBefore tape, still in the grounds many tape limitations.

The tape storage, while it serves for a vital purpose, had many inconveniences and shortcomings. For example, if the file must be renewed, the first task was to find the appropriate archived tape cassette. The tape then had to read the tape unit, which is a process that can take several minutes. When the file was finally placed, it could be transferred, but even this process was often slow. Other problems included bad cassettes, wear of the tape and tape units inoperative.

The assembly of these concerns, operating systems, programs, multimedia files and networks continues to grow, so the idea of ​​restoring the system even pretends. The slow process of supporting/renewal of the tape has become insufficient.

Thanks to affordable and highly capacity hard drives, D2D is the perfect backup solution. Whether you use the Raidvel Fields Fields orExtra hard disk as a shadow disk, D2D can overshadow additional backup strategies ten on one.

D2D provides "immediate" backup and recovery because the system recognizes backup files as originals. There is no tape to tear, wear or scan and no other unit for failure. The files are always useful, restable with simple double -clicking, without having to maintain external archives, as with a tape cassette. D2D used with SATA (Serial ATA) also provides hot exchange when internal preventive monitoring routines warns that the disk is "impaired". In addition, the D2D has full scalability, with a disk field capacity reaching the terabytes. In short, there is no viable disadvantage of using D2D and several advantages.

There are software programs to automate D2D backup. Arctor byteplant GmbH is one of the more popular and can adapt the raid strategy or without air raid D2D. This software can beDownload for free trial and is about $ 40 for purchase. If you are looking for network solutions, more robust software is also available. Finding your favorite software libraries or site will reveal many options.
