Here I am going to present some advantages as well as disadvantages for you all .....choose yourself it will be a online one or offline.




Advantages:-

1.Encryption – When a good service provider is used, they are able to limit the number of people who can access the data by transforming it to make it readable only to people with special knowledge. This prevents external disruptions by unnecessary parties. Such transformations make use of use high-level algorithms.

2.Accessibility – As long as one can access the internet, restoring takes a few minutes. This relieves one from carrying hard disks and other external media forms at all time in case one needs to use stored data. Some service provider update current data as soon as changes are detected.

3.Safety from natural disaster and theft – The data is saved in networks and not in tangible form. Having a company that secures its data in many locations and protects it from natural disaster ensures safety of data. Safety from natural disaster happens only if the backup company has set up the data centers in a way that any natural disaster cannot come into contact with the data even if it’s floods.

4..Advanced setup – There are many available setups on how to secure data and so there is no need to spend a lot of money on such setups. Use the locally available set ups. The set up are easy to access and make data accessible at any time on the web. Costs and time that could have been used on such set ups is saved. They are different and so they cater for the need of many people. It is easy to get a set up that meets your needs.

Disadvantages:-

1.It denies one total control of the data. This does not mean that you will not access it through the web but that there are things you might not be able to do with the data unlike while using offline media, where one has total and direct control of the information.

2.This method limits its use by everyone because you have to be connected to the internet to use it.

3.The time taken to restore or upload data is dependent on the data available and one is at the mercy of the network connection to determine the time taken processing. This is a common problem because only a few people afford fiber optics with a high speed.

4.Total dependence on the internet connection. The speed of uploading, restoring and backing up is fully dependent on the connectivity of your internet. If it is slow, a longer time is needed and if the connection is cut off or is faulty, the process is stopped. The worst thing is that you have little or no control over this and so the inconveniences are inevitable.


Advantages:-
1.It is faster to restore data using this method than the online one, as the server performs one activity at a time. The data being restored cannot be accessed before the process is over.

2.Data that is in the updating process is not backed up. This acts as a safety measure. This reduces tampering with the original data.

3.They are accessible at any time as they are close to one’s working area or at home. The restoration starts as soon as they are plugged in and it can take place when you want to, as their running is not dependent on external sources for the process to take place.

4.They are safe from cyber security breaches. However, when not properly kept, their safety can be compromised.

5.They are portable and can be carried around to store if you want to store them in different locations and in case one wants to always have it as a safety precaution at all times.

6.It is cheaper as there are no monthly charges for the service to be offered, as long as the media has a large storage space, there will be no need for extra costs on storage every now and then.


Disadvantages:-

1.They can be destroyed whenever natural disaster occurs. Calamity may completely cause wiping out of any data on the media and the media itself. Water does not destroy the media but destroys the data which is the most important. Other forms of calamities tamper with data and the media or just the data.

2.The media is prone to theft. Thieves might access private information making it disastrous for the owner. For example, bank details including pin numbers or information that one can use as blackmail against the owner can be accessed from such back-up sources.

3.Hard drives may fail. They malfunction due to a normal malfunction or influence by external sources. The computer, in this case can no longer access the data.

4.Tape disks failure – It is among the most reliable media but when it comes close to or in contact with a magnet, it affects its functionality. They are also affected by weather conditions such as humidity.

5.The database cannot be accessed by the user when the process is ongoing. This wastes a lot of time.
