Email archive: demand of future

Email Archive : Why is it required ?

In Now a day, If your organization / company uses an in-house mail server, an email archiving solution is the only way to take full advantage of the information contained within company emails while simultaneously reducing the amount of storage space required to maintain the messages. Archiving the ingoing and outgoing emails and attachments being sent to and from your employees, also allows you to retain copies in a central location as needed for continuity and compliance, in a manner that provides for future access as needed. It is therefore very important to choose an email archiving solution to improve your company’s knowledge base and address compliance issues by providing swift access to company information, while reducing storage requirements for the files.

The reasons a company may opt to implement an email archiving solution include protection of mission critical data, to meet retention and supervision requirements of applicable regulations, and for e-discovery purposes. It is predicted that the email archiving market will grow from nearly $2.1 billion in 2009 to over $5.1 billion in 2013.

Email Archiving Solutions :

Compliance :
Compliance is rapidly becoming a must-have requirement for many companies. The US is leading this trend, but the rest of the world is following and it will eventually become the norm. 
 
A well-indexed email archiving solution allows your business to not only demonstrate compliance with all email-related business regulations, but also to produce company correspondence if necessary. Current business regulations, such as the FRCP and HIPPA, create specific requirements for companies that correspond with customers via email. In order to prove compliance with these regulations, in the event of a complaint or audit, your organization must be able to produce copies of individual emails sent to customers. In addition, both sent and received email can be subpoenaed during a lawsuit. When a set of documents is requested through the court system, your organization must be able to quickly and accurately produce a large volume of historical communications data by searching and accessing the email archives, instead of combing through the email accounts of individual users.

Storage Requirements :
Without an email archiving system in place, your organization must store emails both on the server and on the computers of individual employees when the messages are downloaded. Although system backups can protect the emails from accidental deletion, this method of email management is both inefficient and redundant.

Your organization can reduce redundancy and speed up your email server with an automatic archival process. Each un-archived email takes up space and slows retrieval and processing on the mail server, as well as the local computer. Automatically archiving email files on a regular schedule ensures that electronic correspondence is removed from the main server to make space for new files. Email archiving improves the response time of the server, while still allowing access to the individual messages when necessary.
Although frequent backups can prevent data loss, and retaining email messages on individual workstations allows your organization to retrieve emails, archival is a better solution. The combination of swift access to files, with a more efficient storage system and the availability of a pool of information for a knowledge base, makes an email archiving solution the only method of storage that provides a comprehensive answer to the challenges posed by an in-house mail server.
Discovery :
Having recognized the business value of email, and implemented policies to retain and archive it as required, organizations will need to search this email for a number of different business purposes such as internal audits, HR requests and compliance supervision.

At the simplest level, most archiving solutions provide a basic search and retrieval capability for data that has been captured and retained within their archive.
However, data captured within the archive may represent only a subset of all available data, so more advanced Information Management solutions provide wider search capabilities that can locate and search all email within an organization, wherever it is located – in an archive, in Exchange, or stored in PST files.
PST Management :
Users may have moved email from their live mailbox out into ‘personal folders’ (otherwise known as PST files) stored locally. They might have used the ‘Auto Archive’ feature in Outlook to reduce the size of their mailbox, or they could be using local folders as a convenient way to store and organize their older email.
Although they are in wide use across many organizations, PST files create a number of problems for IT administrators. From a technical perspective they are not a good way to store valuable data for the longer term as the PST is not a robust file format and is easily corrupted.


These files can be stored almost anywhere – typically on end user devices or network. Although IT administrators know these files exist, they are unlikely to know exactly how many they have within their organization or where they are. As a result they will be taking up a considerable amount of storage and incurring costs, but are probably not being backed up on a managed basis and therefore are liable to be lost or misplaced.

We have seen that archiving provides a reliable and robust alternative approach to long-term email storage, and many archiving solutions provide the ability to ingest existing data from PST files. This will allow organizations to eliminate the use of PST files completely.

Unix Operating system


Dear friends,

This is very common in technical world that first operating system is Unix, But all derivative are questionable to everyone.
So in this blog I'm just giving my knowledge about unix and it's derivative in brief which is collected by me from several places.

Unix and its derivatives :->

A long time ago, the Massachusetts Institute of Technology, AT&T Bell Labs, and General Electric were developing an experimental time-sharing operating system called Multics for the GE-645 mainframe. This operating systems were complex and unwieldy.

 
One day in the late 1960s, Ken Thompson, Dennis Ritchie and a few of their colleagues at AT&T Bell Labs decided to write a simpler version of Multics to run games on their PDP-7, and thus Unix was born.

AT&T held the rights to the code, and licenses were expensive. Many other companies sublicensed Unix and sold their own version. Major players included DEC, HP, IBM, Sun. Unix variants added their own extensions, often nicking ideas from each other and from academia.

Meanwhile, in Berkeley, a number of academics were unhappy with the licensing situation and decided to create a version of Unix that didn't include any AT&T-licensed code. Thus in the early 1980s the Berkeley Software Distribution, or BSD, became a free variant of Unix. BSD first ran on Minicomputers such as PDP-11 and VAXen.

Meanwhile, on the East coast, Richard Stallman threw a fit when he couldn't get the source code to his printer driver. He founded the GNU (GNU's not Unix) project in 1983 intending to make a free Unix-like operating system, only better. After a little hesitation, the kernel of this operating system was chosen to be Hurd, which is going to be usable any decade now. Many components of the GNU project are included in all current free unices, in particular the compiler GCC.

Meanwhile, in Finland, Linus Torvalds went on a hacking binge in summer 1991. When he woke up, he realized that he'd written an operating system for his PC, and he decided to share it by putting it on an FTP server in a directory called linux. The success exceeded his expectations.



Many people created software distributions including the Linux kernel, many GNU programs, the X Window System, and other free software. These distributions (Slackware, Debian, Red Hat, SUSE, Gentoo, Ubuntu, etc.) are what people generally refer to when they say “Linux”. Most Linux distributions consist mostly of free-as-in-speech software, though software that is merely free-as-in-beer is often included when no free equivalent exists.


Other currently existing unices include the various forks of BSD (you get a choice of FreeBSD, NetBSD and OpenBSD, all being free, open and developed through the 'net), as well as a disminishing number of commercial variants targeted towards servers: and AIX, HP-UX, Solaris, and a few very minor contenders. Another proprietary unix-based operating system is Mac OS X running on Apple desktops, laptops and PDAs.

In Future, we may see many more derivatives of this, that means this list will always get increase.
