LTO Ultrium Generations (Key Features and Benefits)

LTO Ultrium Generations

With a well-defined eight-generation roadmap for scalability and growth, LTO Technology is a powerful and adaptable open tape format created to address the growing demands of data protection in the midrange to enterprise-class server environments.

Released Generations Include:

Generation 5

With capacity of 3 TB (assuming a 2:1 compression), the latest generation in the LTO family provides data transfer speed of up to 280 MB/s (assuming a 2:1 compression) and adds a new partitioning feature and Linerar Tape File System specification to provide enhanced file control and data management. The LTO Ultrium format generation 5 specifications were made available to licensees in January 2010.

Generation 4

Delivering 1.6TB (2:1 compression) and up to 800 GB native per cartridge, Ultrium format Generation 4 provides data transfer rates of up to 240 MB/second (2:1 compression), the LTO Ultrium format generation specification was made available to licensees in late December 2006.

Generation 3

Featuring capacities of 800 GB (2:1 compression) and up to 400 GB native per cartridge, Ultrium format Generation 3 provides data transfer rates of up to 160 MB/second (2:1 compression) for the third generation of the 8-channel version. Generation 3 licenses became available on July 26, 2004 with products appearing in late 2004.

Generation 2

With a cartridge capacity of up to 400 GB (2:1 compression) and up to 200 GB native, Ultrium format Generation 2 provides data transfer rates of up to 80 MB/second (2:1 compression). Licenses for Generation 2 became available in April 2002 with products appearing in late 2002.

Access Facebook on any Mobile Without the Internet

Do you have an old mobile phone, like the Nokia 1100, that has no browser and can do little more than make phone calls? Or are you stuck in some remote place where there’s no Internet or no other form of data (EGDE/GPRS/3G) connectivity is available?

Not a problem. You can still use your Facebook account in India by dialing *325# (or *fbk#) from your mobile phone – this service requires no data plan or Internet and it will even work on phones of the Stone Age. Here’s a quick tour:

        

Use Facebook without the Data Plan

Facebook India has partnered with Fonetwish to bring Facebook on every mobile phone without requiring any apps or even the Internet.

You dial the *325# number, then enter your Facebook username and password and you are in. You can then send number based commands to access various features of Facebook, chat with friends who are online, add new people to your friends list, and more.

I played with the service for some time and it was a nice experience overall. If there were a Unix-like shell interface for Facebook, it would be much similar. Fonetwish says that this service is currently available for Airtel, Aircel, Idea and Tata Docomo users in India.

It may be too much work to read your Facebook news feed stories one by one but this is a good option to quickly update your Facebook status or for chatting with friends who are online. The price is reasonable too – you just have pay a subscription fee of 1.00 per day for unlimited usage.

Related: If you have an old mobile phone, you can search Google by SMS without requiring a data plan.

Search Google on your Mobile Phone via SMS Text Messages

This is something for mobile phone users in India who don't have a web-enabled phone – you can now search for information on Google using SMS. The service has been around for a while but Google is no longer charging a premium fee for sending you the SMS message.

The Google SMS search service may be used for finding movie timings, weather, nearest pizza restaurant, currency conversion, train schedules, cricket scores and a host of other things.

One of the very useful features in SMS search is language translation. For instance, I could SMS "say hello in French" to 9-77-33-00000 to get the right French word.

Google SMS Search could be real bad news for the business of services like Indiatimes that charge a premium fee for delivering news or astrology updates on the mobile phone using short codes.

For details go to the Google Mobile website or check their help center for more details.

The Google blog says that you only need to pay the standard SMS text charges for sending the SMS query to Google – there's no fee for the incoming messages from Google. The service is available for all popular cellular networks including Airtel, BSNL, Idea, Reliance, Spice, Tata Indicom and Vodafone.

Difference between: Full, Differential, and Incremental Backup

Submitted by Laxman (chinnilax@gmail.com)

Type	Definition	Benefits	Drawbacks
Full Backup:	A complete backup of everything you want to backup.	Restoration is fast, since you only need one set of backup data.	The backing up process is slow. High storage requirements.
Differential Backup:	The backup software looks at which files have changed since you last did a full backup. Then creates copies of all the files that are different from the ones in the full backup. If you do a differential backup more than once, it will copy all the files, or parts of files that have changed since the last full backup, even if you already have identical copies of those files in a previous differential backup. For restoring all the data, you will only need the the last full backup, and the last differential backup.	Faster to create than a full backup. Restoration is faster than using incremental backup. Not as much storage needed as in a full backup.	Restoration is slower than using a full backup. Creating a differential backup is slower than creating an incremental backup.
Incremental Backup:	The backup software creates copies of all the files, or parts of files that have changed since previous backups of any type (full, differential or incremental). For example if you did a full backup on Sunday. An incremental backup made on Monday, would only contain files changed since Sunday, and an incremental backup on Tuesday, would only contain files changed since Monday, and so on.	This method is the fastest when creating a backup. The least storage space is needed.	Restoring from incremental backups is the slowest because it may require several sets of data to fully restore all the data. For example if you had a full backup and six incremental backups. To restore the data would require you to process the full backup and all six incremental backups.
