SAFETY IN THE CLOUD

Look up in the sky, it’s a bird, it’s a plane, NO!  It’s Sky drive -the future- that backs up data in a cloud. You have heard the popular saying “one day, we will build houses in the sky”. Well the ICT world is ahead, putting in place means for ‘storing data in clouds’. Rain clouds you say?  Of course not! A cloud in IT will only have meaning when concatenated with “computing”.

Cloud computing comes into focus when you think about what IT always needs – a way to increase capacity or add capabilities on the go without investing in new infrastructure, training new personnel, or licensing new software.

 

Before focusing totally on skydrives and cloud computing, I would like to remind you about other types of storage devices still being utilized. We shall also tell you which one is best and why, the best time to back up and how to remind you to back up.

1)      Floppy disks: this is slowly being phased out – if it hasn’t been completely – we have two types.    3½ and 5 1/4. They are used to store data of less than 10MB in size. It is not suitable for places that require large storage of data.

 

ADVANTAGES

i.)                  It is affordable

ii.)                 It is portable

DISADVANTGES

I)        It does not allow for large storage

II)      It is slowly being phased out.

2)      CDs/DVDs:  they are capable of holding up to 8GB worth of data. Contrary to popular belief, they can transfer viruses -not all of them though- the ones which can transfer viruses are the writeable and rewritable discs while the readable ones cannot.

 

ADVANTAGES

i)                    It is affordable and easy to use.

ii)                   It is portable

iii)                 It allows more space for storage than the floppy disk

DISADVANTAGES

i)                    It can easily be damaged

ii)                   If the lens of the disc drive becomes weak, data cannot be read

3)      Flash Drives and Hard Disk Drives: Data can be backed up to another storage device which uses USB ports. These devices are portable and can be used to transfer and back-up large data. Though special care must be taken to avoid it going bad.

 

ADVANTAGES

i)                    It allows the most storage for data

DISADVANTAGES

I)                    If the hard drive becomes unreadable, data can be lost completely.

4)      SkyDrive: Skydrive is based on the principles of cloud computing.

Cloud computing is at an early stage, with a crew of providers large and small delivering a slew of cloud-based services, from full-blown applications to storage services to spam filtering. Yes, utility-style infrastructure providers are part of the mix, but so are SaaS (software as a service) providers such as Salesforce.com. Today, for the most part, IT must plug into cloud-based services individually, but cloud computing aggregators and integrators are already emerging.

We have two types.

The first allows a single application to be used by a thousand customers. No investment in servers is required. It is called SaaS.

Secondly, the utility computing offers storage and virtual servers that IT can access on demand.

ADVANTAGES

i)                    It provides the most secure form of backing up.

DISADVANTAGES

I)                    Because of the nature of our internet service, it is not advisable.

Sky Drive utilizes the cloud computing principle but it really means backing up your files online. Microsoft and Google offer this.

IMPORTANCE OF BACKING UP

John has been working with a reputable company for over 3 years. He sees how his superiors in the IT room handle networking issues on a daily basis and has always been impressed. One day, he decided to go for the well known professional course Cisco Certified Networking Associate (CCNA). It took him 4 months to read and pass. He came back all smiles and resumed work.

A couple of weeks later, he was put on night duty and was told to monitor the network. He was grinning from ear to ear; because this was the first time he was going to be alone. One of his superiors, Dipo, was at the hospital expecting his first child while the other, Charles, left the office early as he wasn’t feeling too well.

John who passed the professional exam without actually using a live router decided to use this time to experiment and forgot to save the configuration of the router. After a couple of minutes, he crashed the network. Devastated, he knew with this, he was certainly getting the boot in the morning. He called Dipo telling him what he had done. Dipo in a calm voice told him that he will be with him shortly.

Dipo arrived an hour later, and within 20 minutes, he had restored the network. Curious, John inquired of Dipo asking what he did. Unknowingly to John, Dipo had told Charles to copy out the configuration before leaving the office every night.

WINDOWS BACKUP

Windows gives you the opportunity to back up your files with the automatic backup and restore feature. It can be found in the control panel and it is very easy to use.

select backup and restore

select set backup

Select where you will like to back up to

That is all there is to It.

That brings us to the end of this week. Have a lovely weekend.
