One might think that every company, every government agency and every administration nowadays has a modern backup strategy. Unfortunately, this is not the case – many businesses still rely solely on their local backups. Cyberattacks – for example, through ransomware – impressively show, however, that this type of data backup alone is not sufficient to be adequately protected.
However, it's not just hacker attacks that pose threats that cannot be resolved with local backups. For example, files might not be backed up or restorable in full. Fires or water damage are also underestimated but realistic dangers, as they can destroy not only the primary data but also the local backups.
A rule to follow when backing up data is 3-2-1 Backup Rule, which is briefly explained below.
3 – Three data copies
Users should create at least three copies of the data so that nothing can be lost in a worst-case scenario. An original should be primarily stored, and backup copies should also be made.
2 – Two different media
Different technologies and media types have different weaknesses and vulnerabilities. By storing files and their copies in different ways, the likelihood of data loss can be significantly reduced. Care must be taken to ensure that the storage alternatives have good protection features.
1 – A backup in an external location – the offsite backup
It is self-evident that data located in the same place is highly likely to be lost together in an emergency. Therefore, one of the backups should be stored externally.
A good backup strategy must therefore include at least one offsite backup.
An offsite backup is the storing and securing of a backup copy in a safe location, external to the company's infrastructure. There are two approaches to this: the classic method involves storing data carriers such as hard drives or memory cards externally. However, this requires too long a recovery time in emergencies and demands considerable effort. Alternatively, there are innovative, cloud-based solutions that are ideal for small and medium-sized businesses, as they eliminate the need for deployment and costs for hardware and software licences, and require no support or administration from the business itself.
No backup strategy without good planning
3-2-1 and the backup is mine? – It's not quite that simple, of course. A good backup strategy requires a considerable amount of thought and planning before implementation. Areas of responsibility and competence must be defined, and the procedure determined. What is backed up and how often? With what tools and on which systems should the backups be secured? And many other aspects must be considered beforehand.
Furthermore, the number of backup copies, the storage media used, and offsite locations can all be individually adjusted to suit your own needs. For example, a 3-2-1 backup can be turned into a 6-4-2 backup.
Therefore, developing an appropriate and professional strategy requires considerable effort and expertise. We are certified to ISO 9001:2015 (Quality Management) and ISO/IEC 27001:2015 (Information Security Management) and will find the right solution for you to best secure your company data.
