The U.S. Central Intelligence Agency (C.I.A.) is 100% on board with moving
towards Cloud Computing. They have built a secure internal cloud that enhances
flexibility and keeps secret data safe.
According to Jill Tummler Singer, the CIA’s deputy CIO, Cloud computing can
give IT environments the ability to be more flexible and more secure if designed
behind a firewall.
It used to be that you would backup everything on your computer by using floppy disks.Today, when one sound or graphics file can easily be larger than the capacity of a disk, it would be impractical to back up even you documents using floppies, let alone your applications. Luckily there are better options including Zip disks, CD writers, tape drives, external hard drives and even online backup services.You can also compress all of your backed up files so that they will take up less space.Follow the following pointers and you will be able to find the media that is best suited to your needs.
1) Determine the approximate quantity and file sizes you will be backing up.
2) Figure out the quantity and file sizes of any documents or other applications you want to archive permanantly to a backup device or removable media.
3) Plan for that amount of information to grow in the future.
4) You should figure out your budget for a backup storage device and removable media to use with it.
5) Consider if you plan to archive photographs or scanned files, need portability of the media or the drive itself, wish to record music for playback on some other equipment, or need ease of use.Weigh these factors along with your need to back up the files.
6) Work out the cost per MB of media for each drive you are considering.zip drives themselves are cheap however the disks are not.
Imagine you have spent ages writing a report or another important piece of work that has to be submitted tomorrow.Suddenly, your hard disk crashes and all of the hours that you have put into writing that important document have just gone up in smoke.Don’t be tempted to jump on the bandwagon of those who say “it will never happen to me!” as probability will dictate that if you don’t take action soon, one day it inevitably will.So how can you prevent such a disaster occurring? This is precisely what data backup is all about.
Data is often the most important part of computer usage as it can often take months or years to accumulate relevant information.As technology has become more reliable, the risk of losing information has been significantly reduced however it would be needless to lose documents due to lengths that you yourself could have taken to prevent such an occurence.
There lots of devices that will allow your data to be backed up. Commonly used devices are external hard drives, CDs, DVDs, USB drives and for more sensitive information there are companies and services which will provide you with secure online data backup. Whenever you backup data to an external device, said device should be stored in a different location from the original computer in case a fire or local electrical surge should damage the data backup hardware.
Data backup is at it’s most useful when done constantly and within reason.For example – if you are spending a long time working on a lengthy document, you should not leave a significant amount of time before saving your work. Consider the effort that it would take to redo the work since the last save in the case of a crash and make a judgement call as to how often you save your work.
