The process of backing up your data has also progressed from manual backups to automated backups using mechanisms such as tape libraries, offline backups to online high speed mirroring, and in-house storage to off-site storage at third-party data custodians.

Hence, data backups are a must even today. Although over the last few years, the reliability of the hardware and software systems has increased, there are still the risks of crash of the hardware, operating system, applications, and databases resulting in data loss or corruption. Data backups provide for continued operation by effective restoration of data and assure continued availability of the systems albeit the time taken for bringing up of the system by restoring the data for the corrupted or crashed part of the system. Data backups stem from the fact that the disks on which the data is stored are prone to failures and can lead to a single point of failure. Data backups are the first line of defense against crashing of systems, corruption of data, exploits leading to data integrity issues, and accidental loss of data. Data backups help in ensuring restoration of data in case of data loss, data corruption, and data integrity issues.Īs we have seen in previous chapters, “Availability” is one of the important aspects of information security. The cloud infrastructure helps with effective data backups and is a low-cost disaster recovery option. Cloud computing, on the other hand, is a relatively recent phenomenon. Data backups have been common since the inception of computers. Data backups and cloud computing can be treated as two separate subjects in one context and can be considered as complementary in another context.
