deduplication software

Storage has been a major drag to reduce operating costs, although the cost of storage has been decreasing in recent years, but the growth rate of enterprise data is far more than the reduction of storage costs, so how to reduce the pressure on the storage to the enterprise is a big test for IT staffMicrosoft has brought a surprising feature in Windows Server 2012, called Deduplication, which allows Windows Server 2012 to store more data in less physic

For SQL deduplication, I would like to briefly introduce myself. If you have any suggestions or do not understand it, please give it a little more. There are two common ways to remove SQL deduplication: DISTINCT and ROW_NUMBER (). Of course, ROW_NUMBER () has many important functions besides deduplication, I will give you a brief description of what I actually us

Javascript implements multiple methods for Array deduplication, and javascript implements arrays. Don't talk nonsense, just pick up the dry goods! Let's talk about the requirements of this instance: Write a method to implement de-duplication of arrays. (Requirement: Execute the method, pass an array, and return the new array after deduplication. The original array remains unchanged. During implementation, o

concluded on his blog that extreme tolerance for errors is an essential quality for managers. I also summarized it myself: medicine is the precise control of fuzzy, and management is the precise fuzzy management. Let me talk about the relationship between error and efficiency. Errors and efficiency are a pair of conflicting communities. There is a relationship between errors and efficiency in life: "radish is fast, don't wash mud"; "slow work is fine", etc, they all provide a thorough explanati

What should you do if the recovery data grows too large and traditional disaster recovery methods cannot achieve the goal? Some new technologies, such as deduplication, storage Tiering, and data management policies, can help you reduce the high cost of disaster recovery, at the same time, it can also achieve the expected recovery time objective (rediscovery time objective or RTO ). In the previous article, we gave an example of a company ignoring the

Capacity optimization. Data deduplication in Windows Server 2012 can store more data in a smaller physical space. It achieves higher storage efficiency than previous versions that use single Instance storage (SIS) or new technology file system (NTFS) compression. Data Deduplication uses sub-file variable-size chunking and compression, and the optimization rate for regular file servers is 2:1, while virtual

Deduplication has been widely used in data backup. We found that for backup applications, we can delete and compress data by repeat data about 20 times, thus saving a lot of storage space. How can I retrieve duplicate data blocks? If byte-level comparison is adopted, the performance of the entire system is certainly unacceptable. To solve this problem, you can use the data fingerprint technology to retrieve duplicate data blocks. The principle of this

PHP two-dimensional array deduplication method (retain each key value while removing repeated items)-uniqueness of the two-dimensional array. PHP two-dimensional array deduplication method (retain each key value while removing repeated items) -- The uniqueness of the two-dimensional array requires deduplication for the following two-dimensional array: $ arrarray

This article mainly introduces python's implementation of text deduplication without disrupting the original sequence. For more information about python's implementation of text deduplication without disrupting the original sequence, see the next article, for more information, see The code is also found on the Internet, which is very efficient and especially suitable for

VNX data block deduplication can be enabled on each Pool.1. To enable deduplication for a traditional RAID group LUN, you must first migrate it to the storage pool ).2. Once deduplication is enabled, the LUN will be migrated to the deduplication container. After the migration is complete, the LUN will become Thin LUN.T

I found that the prefixes of several blogs are "not simple", which roughly describes the status of a seemingly simple task. It is not easy to find out after practice. A lot of things are like this. If you do not do it yourself, if you do not study it carefully, you can only be in a confused state.This reminds me of another story. When I graduated, I was interviewed by a CTO from a company. He told me a word that makes me still remember it, he told me that technology is actually very simple (a Da
