Everybody, whether as an individual or company, needs to take care of their data. Your personal certificates, photos, notes, work history, music, client lists, supplier database among others are just some of the data that you do not want to lose. When it comes to security, it all begins with a solid backup plan.
Data protection involves three main stages namely; backup, retrieval plan and time taken to complete these processes. Backup alone does not provide the full protection but the first step towards data protection. It only offers a solution to make it available in case the original files have problems. Data can be corrupted or lost, and this is where backup comes in handy. It is easier to restore lost or corrupted data if there is another copy of it somewhere.
Popular types of data backup
There are several types of data backup plans. The primary ones are:
1. Full backup. It keeps a copy of all your data in another media such as an external disk or cloud. It ensures that the data is retrieved faster when need arises. Requires a lot of space that can accommodate all your data as well as time to copy all your data.
2. Incremental backup which creates a backup of all modifications that occur since your last backup. This kind of data backup only recent modifications and therefore saves you both time and space. You will be able to see the date and time of the last backup.
3. Differential backup copies all changes that occur between the first and last backup. This plan therefore takes a little more space than incremental backup.
You can run backups daily, weekly or monthly. To save on time and space, run a full backup during the first time and then choose either incremental or differential backup on subsequent operations. Nevertheless, the plan you choose highly depends on your needs, space available as well as your financial status.
