Keeping in mind these aspects, many open source backup software have been developed over a period of years.ĭata backup comes in different flavours like individual files and folders, whole drives or partitions, or full system backups. After taking a backup, we have to also make sure that this data is secure, is manageable and that the data’s integrity is not compromised. Many corporates and enterprise level customers are generating huge volumes of data, and to have backups is critical for them.īacking up data is very important. When we exceed the allowed storage capacity in these devices, we tend to push this data to the cloud or take a backup to avoid any future disastrous events. Today, we are generating a lot of data by using various gadgets like mobiles, tablets, laptops, handheld computers, servers, etc.

What are the advantages of having backup of data? Now, since storing data is not at all costly compared to what it was in the 1970s and ‘80s, why should one take backup of data when it so cheap to buy new storage. The general assumption is that this cost will be reduced further. The graph in Figure 1 gives a glimpse of this. The cost per GB of data has come down significantly over the years because of a number of innovations and advanced techniques developed in manufacturing HDDs. Nowadays, new computers are increasingly adopting SSDs (solid-state drives) for main storage, but HDDs still remain the champions of low cost and very high capacity data storage. The year 2016 marks the 60th anniversary of the venerable hard disk drive (HDD).

The commercial use of hard disk drives began in 1957, with the shipment of an IBM 305 RAMAC system including IBM Model 350 disk storage, for which a US Patent No.
