The backup technique due to repetition removal is utilized in the maximum

Recently, large-scale forest fire occurs in California, but excessiveness hundreds in the area such as that exist you call as for data center and IT section trying whether probably to be all right, there is no. According to reporting the building which exceeds 2,100 receives damage, you say that in that also many enterprises are included. In contingency planning plan of most IT section, the data every night is retained in the tape inside the fire-resistant safe, the backup technique that is included, it transfers the data to the storage facility outside the sight periodically, but also redundancy of the extent backup data where the quantity of the data which is collected from the document, the E-mail program and the media file is many becomes high. While backing up when it retains to the unnecessary data, the storage space and budget instantaneously are depleted. Probably there is no method feeling at rest, of decreasing the consumption of the wasteful storage territory, reducing cost? Just that is repetition removal (deduplication).

Repetition removal with, it is the technique which removes redundant information from the data of the system before the transferring to the secondary storage. As for the reason where IT section does repetition removal during backup processing it is several. The disk space can be used efficiently, it is something where it can accelerate the data transfer to outside the sight, the IT staff from it can back up the system in addition as the opposite and it can start the time of obstacle restoration at brief.

Those where repetition removal is used frequently are the branch office office which transmits the system data to the nightly head office office for update execution of retention and system scale of the data and the enterprise which has the remoteness facility. However, it is possible to retain the data on the computer the place, in fact to receive the benefit of repetition removal at any enterprise.

As for the analysts of data storage industry, as for repetition removal it is the serious element of backup processing, that, you express several years later it probably becomes industry of 10 hundred million dollars.According to the reportSimon Robinson the storage-related investigation director is served with The 451 Group, as for market scale of repetition removal you say that it is the possibility that it reaches to 2 hundred million 6,000 ten thousand dollars to end of this year.

There is plural primary factors in the background where the interest for repetition removal has increased suddenly, that Robinson talks. "To be largest, it is dense Toda who reaches the point where it can utilize the disk drive for backup low at cost. User when if anything the tape compared to wishes to back up the data in the disk, (speed of restoring and other than height of reliability, the time the disk surpasses even in the cost performance). After becoming something where the backup by the disk is realistic, industry searched the method of streamlining this method more.by the fact that the redundancy which is the thing concerning former backup is lost, actualizes this is one of splendid methods ",

According to Robinson, if repetition removal is used, as for enterprise compressing the possible limit data, because it becomes possible, to insert in the storage disk, as for this technology you say that it can produce profound effect on IT budget of enterprise. "In the disk system which only backup of 1 months is produced so far, it reaches the point where it can back up of 1 year semi- year's amount, depending upon when". In addition as for Robinson, because data transfer with wire becomes easy depending upon repetition removal, rather than conveying the tape to the facility outside the sight one by one, for enterprise the method which saves the secret data has become favorable.

The enterprise which examines repetition removal before lowering last decision, probably will have the necessity to consult the bender of several corporations. At that time, the question which it should ask is several.

* The product which it corresponds to the scale of the respective company system?
* As for recovery at time of obstacle which extent simplicity?
* At the respective company you can use with the hypothetical conversion product of the introduction being completed?
* It supports, also other function such as data movement to the tape?
* The product which produces the effect of some extent on performance of the respective company system?
* How you guarantee that just the redundant data is deleted?
* As for the data how being processed? As for in-line processing, when hindrance does not occur in work flow, or when competition of the system resource does not happen, makes, follow-up maintenance such as indexing and the preparation work of considering the backup of the next time which scheduling is done possible. In addition, after-treatment refrains after the backup ending. After-treatment on the necessary sufficient maintenance picture or in the form where time is not required more is utilized at many enterprises
