The paper “ The Backup Process - the Data Backed Up and Restored Automatically When Required and Is Secure from Any Interference or Data Loss” is a thoughtful example of an essay on information technology. Every organization, no matter the size, uses data for their day to day operations. It is important for organizations to ensure that their data is safe from any harm. This can be achieved by having a data back up either locally or on “ cloud” . Data backup is the process of ensuring that an organization has a copy of their data in case the original data is harmed.
For example, by fire, floods among others. Data backup can be done locally by keeping a copy of files on a different drive, for example, CD, tapes, Flash disk among others. The other way to keep a backup is by the use of software as a service (SAAS). SAAS can be defined as a software model where applications are hosted by a service provider and a user can access them through the internet. This is a new technology and it is gaining popularity among businesses.
This approach has some benefits associated with it. For example, unlike in the past where companies had to maintain their IT infrastructure, SAAS gives them an alternative whereby they can just plug in and subscribe to the same services over the internet. Another benefit is that it is available from anywhere, anytime from any machine. There is a low cost associated with SAAS this is because the company does not need initial cost to build the IT infrastructure and there is no maintenance cost.
Some examples of SAAS are google docs, salesforce among others. Google docs as a SAAS is my choice for this project. Google docs are the largest online document archive cloud platform in the world. There are some benefits associated with google docs. The main benefit is online availability that is, one can work with it from anywhere and easily provided there is an internet connection. Secondly, it supports different file formats. For example, documents, spreadsheets, drawings, presentations, and web forms. Thirdly, it makes it easier for corporate communication this is because communication is real-time and there is efficient file sharing among the workers.
Fourthly, you can edit all your documents online and save them all from a browser. These benefits are making google docs more popular and become the preferred mode of online data storage for many people. Google has over one million servers and several hundreds of millions of customers, Google handles a large amount of data which can make the backup process complicated. Google doesn’ t have a defined backup system. It uses the failover strategy whereby once one saves a document on Google docs, it makes copies of the same on two different servers, which are located on two different Datacenters.
This covers the whole backup and recovery needs of Google. The RTO for Google is basically zero. It uses instant failover for recovery (Preston & Skelly, 2002). There is no documentation on how google performs its backup process but this is how it can be performed. The backup process has many different ways of execution. You can do an on-site backup or do an off-site backup. In this case, I will use the off-site backup plan.
First, I will have to ensure I have a first-level backup which will be located on-site. For an off-site backup, we will need to create a VPN for security purposes. A Virtual Private Network uses the virtual tunneling protocols that ensure the security of data being transmitted via the VPN. The Network-attached storage will be located off-site where it will be accessed via the VPN. After that, we will have to decide on the software to use for the actual backup. We can use third-party software like i-drive, carbonite, or Backblaze.
Alternatively, we can use the windows backup feature. In my case, I will prefer the windows server backup feature. The central server which will serve as a first-level backup option on-site is where all the clients’ machines will be backing up their data from. This will ensure that there will be two copies of the data on-site. One on the client machine, and one on the server. Then I will need to install power backups in the location where the Network Attached Storage (NAS) will be, this will ensure that the offline device will always be online (Woods, 2005).
