Data backup should be a routine in both small and large organizations. Individuals with personal computers also need to back their data to ensure all their databases and files are safe after equipment failure or other disasters. There are various solutions available to help you back up data. Your choice should be influenced by the type and amount of data you want to preserve.
This comprehensive solution copies all the data you want to back up. It offers adequate protection but it tends to be time consuming. You will also need several disks or tapes to store the data. The advantage is that it offers simple and fast restoration. This solution also allows you to maintain different versions of the backed up data.
This is considered an alternative to the time consuming full backup solution. Incremental backup usually takes a shorter period and it only backs up changes in the stored data. The drawback is that restoration takes longer and you may lose some data if a number of files are damaged or misplaced.
This solution backs up any changes made to the data since the previous backup. An initial backup is carried out and subsequent backups are done whenever changes are made. This simplifies the backup process. The data backup also requires less space compared to full backups because only changes are copied. Differential backup takes longer and storage space use is not as efficient when compared to the incremental solution.
Explore these three main backup solutions and identify a suitable one depending on your individual or organizational needs. Think about what your service-level contract dictates in terms of recovery time when making a choice. You can also consult a data backup expert to help you select an ideal solution. This can save you a lot of frustration and expenses in case of data loss.
