A guide to backing up your data

Friday, August 31st, 2012

Or maybe the title of this article should rather read “How to beat procrastination in 5 easy steps”. Because, and let’s be honest here, there are a multitude of more interesting things I’d rather be doing than backing up my data. So rather than just schedule backups each week, I procrastinate and do something else.

Unless you enjoy to redoing all your hard work from scratch and losing  precious data in the process, it might be a good idea to get into the habit of data backup. Choose one day a week when things are a little less chaotic than usual, maybe a Friday and make an appointment in your diary to do a weekly backup. Soon enough you’ll be backing up like a pro without any effort.

Try not to overwrite your previous backup. Rather make consecutive copies in various folders on your external hard drive or on your network space and name each with the particular day’s date. If any of the documents become corrupt for some reason, you can always fall back on a previous version.

Regularly check that the medium on which you made your backup is still in working order and you’re able to access your documents. For the same reason use more than one backup medium, for example your network space AND an external harddrive.

In a previous newsletter we told you about the new Sharepoint version implemented on campus. Sharepoint is an effective and powerful information management and collaboration tool, where team members can share data and work together. However, SharePoint is not intended to be used as a platform where users can backup their data.

SharePoint 2010 is currently mostly utilised for Teamsites, which are mainly used by groups (faculties or departments) and one member of this group is then assigned the responsibility to manage documents and permissions on the group’s site.

Each staff member has access to his/her own network space where you can save an allocated amount of data for free. If you choose to have your data closer at hand, get yourself an external harddrive or even dvd’s (although the amount of data you can save on dvd is a bit limited) Never save important data on a flashdrive – it’s sole function is for transporting data from one device to another and is not a dependable medium for backup.

Your last option for data storage, is the “cloud”. By now you know everything there is to know about clouds, the various services and their advantages and disadvantages. Just remember two important facts about clouds. Use cloud storage only for your personal information, not for any academic information or sensitive data.

Also, if you use various devices, remember your cloud service will sync between each of them every time. If you have 500MB data and three devices, you will pay for 1500MB data. This might not sound like much, but if you use a 3G modem, the cost will be very high.

What is the “cloud”?

Friday, August 31st, 2012

This isn’t a philosophical musing or the start of a poem. We’re referring to the type of cloud containing data, not water. The latest buzzword the past few months is “cloud computing”, but what is “the cloud”?

Cloud computing is the use of computing resources (hardware and software) delivered as a service over a network (typically the Internet). In other words, it’s a grid of computers set up in such a way that it can host a service to deliver software and data. Websites and server-based applications run on specific computers or servers.

The difference with a cloud, however is that the cloud uses a collective virtual computer, which runs independently from another computer or specific server configurations. To quote T. Grance and W. Jansen (Guidelines on Security and Privacy in Public Cloud Computing) – “The common characteristics most (clouds) share are on-demand scalability of highly available and reliable pooled computing resources, secure access to metered services from nearly anywhere, and dislocation of data and services from inside to outside the organization.”

With broadband internet, the need to have the software run on your computer or on a company’s site is becoming less and less essential. A lot of the software that people use nowadays is completely web-based. The cloud takes advantage of that to bring it to the next level. Proponents claim that cloud computing allows enterprises to get their applications up and running faster, with improved manageability and less maintenance, and enables IT to more rapidly adjust resources to meet fluctuating and unpredictable business demand.

End users access cloud-based applications through a web browser or a light-weight desktop or mobile app while the business software and user’s data are stored on servers at a remote location.Cloud computing relies on sharing of resources to achieve coherence and economies of scale similar to a utility (like the electricity grid) over a network. At the foundation of cloud computing is the broader concept of converged infrastructure and shared services.

Please keep in mind that cloud storage is NOT recommended for institutional and academic information (see definitions below). If you do decide to make use of cloud storage, rather use it for your personal information or non-critical information.

In terms of the draft Information Management Policy, the following information categories and sensitivity categories are defined:

1.1.1.      Two overarching information categories are defined:

a)      Academic information is information that comprises academic content (including library, learning materials, research output, etc.).

b)     Institutional information is information that the University as organisation, including its staff, students and other stakeholders, owns, or is the custodian of, as well as any information that is not classified as academic information.

1.1.2.      Four categories of information sensitivity, in descending order of sensitivity, are defined:

a)      Confidential information is information that was provided or is used in confidence and that may only be accessed by or shared with authorised persons on a need-to-know basis.

b)     Personal information is a specific type of Confidential Information and is defined as information that can be used to identify an individual or information about an identifiable individual and information that is defined by relevant legislation as personal information.

c)      Operationally sensitive information (default sensitivity) is information that is used in the day-to-day operations of the University and is classified as sensitive to very sensitive depending on the extent to which its divulgence will adversely affect the University’s image or operations.

d)     Public information is published for public or general.

Which one to choose?

Friday, August 31st, 2012

Now that you know what a cloud is, is your next challenge to make a choice from the multitude of available options. We tried to figure out which is which.

ICLOUD Apple’s  iCloud-diens looks highly effective and works like a dream (or so they say) It synchronises your Apple devices –  iPhone, iPad and Mac and has a lot of added functionality. Especially handy if you’re a big iPod-fan, regularly download music an need somewhere central to store it. iCloud gives you 5GB free storage space, but for more you have to pay.

AMAZON CLOUD DRIVE
Cloud Drive functions exactly the same as a harddrive – the only difference is it’s not in your pc on your desk, but online. Amazon gives you 5GB free, but for more you have to pay 1$ for 1GB per year. It also has a Cloud Player Music stream application for all your audio needs. The disadvantage to Cloud Drive is it’s dependency on Flash and if you have iOS devices without Flash, this might not be for you.

GOOGLE DRIVE
Google has a wide range of services – Picasa for photos, Gmail for email, Music Beta for music and Google Docs for documents. While SkyDrive and Dropbox allows you to store files of up to 2 GB, Google allows 5 GB. Google also has more paid options than DropBox or SkyDrive. SkyDrive has three, Dropbox two, but GOogle has no less than nine! You het 1GB free for Google Docs, 1GB for Picasa, 7GB for Gmail and you can upgrade to 16TB at a cost of 4000$ per year. Google Drive is probably the most accessible of the cloud storage options as you only need a web browser to access it.

WINDOWS SKYDRIVE
This service is very similar to Amazon’s and of course, a Windows orientated product. If Office takes up a lot of your time, this might be the logical choice for you. SkyDrive allows 7GB free storage and a whole 25GB if you’ve been a user before. Cost of paid service are also more affordable than the others. If you use the SkyDrive application, you’re unfortunately forced to sync everything to your pc. You can’t select single or certain folders only. Another alternative for Windows users is Windows Live Mesh. Read more about it on Wikipedia. 

DROPBOX Probably the best known cloud storage service around. All your devices can be connected to DropBox and seamlessly integrated. Anyone with a web browser or the DropBox application installed on their pc, can use their service. Although Dropbox is an effective and easy service, it’s unfortunately also the most expensive. In spite of the huge choice of cloud storage providers (and we haven’t even mentioned all of them), in the end the choice is yours.

Wikipedia at your fingertips

Friday, August 17th, 2012

Did you know you can have Wikipedia – the all inclusive, all knowing, unofficial central source of all information on the internet  – on your own pc? *

Neither did we. Just imagine how handy this could be next time your internet connection drops for the umpteenth time and you’ll still have your own local version of Wikipedia available.

Hadlee Simons from iafrica’s cooltech has all the information you need.

* Never heard of Wikipedia?

Wikipedia (Listeni/ˌwɪkɨˈpiːdiə/ or Listeni/ˌwɪkiˈpiːdiə/ wik-i-pee-dee-ə) is a free, collaboratively edited, and multilingual Internet encyclopedia supported by the non-profit Wikimedia Foundation. Its 22 million articles (over 4 million in English alone) have been written collaboratively by volunteers around the world. Almost all of its articles can be edited by anyone with access to the site, and it has about 100,000 regularly active contributors. As of August 2012, there are editions of Wikipedia in 285 languages. It has become the largest and most popular general reference work on the Internet, ranking sixth globally among all websites on Alexa and having an estimated 365 million readers worldwide.

Wikipedia was launched in January 2001 by Jimmy Wales and Larry Sanger.Sanger coined the name Wikipedia, which is a portmanteau of wiki (a type of collaborative website, from the Hawaiian word wiki, meaning “quick”) and encyclopedia.
