3 golden tips for reliable backup

Everyone has lost important documents before. Dropped your smartphone, your laptop got stolen on the train, a ransomware virus... There are dozens of possible scenarios where you'd better have a backup.

Especially if you have a business, a backup is vital. It doesn't always have to be hackers or viruses, a stupid accident such as a failed synchronization can have a terrible impact on business operations.

As an IT company we work with the data of others every day, so the first lesson we teach our employees is the importance of reliable backups. And because in these tele-working times everyone has to be a bit IT savvy, we would like to share the three golden tips with you!

Golden tip 1, take a NAS

A NAS (network attached storage) is a kind of computer, especially for storing (a lot of) data. It is best to place a NAS near your home or office, close to your most important devices. Because we have a lot of devices nowadays (smartphone, laptop, camera, ...) it is more efficient to centralize the data on your NAS, before storing a backup in the cloud.

You can get a NAS on the market, but often software is a dead end. At continu.online we assemble our systems ourselves and use Debian GNU/Linux as our operating system. That OS has a very high reliability and gives us the flexibility to handle any type of backup situation.

If you want to get started by yourself, you can get a good result with FreeNAS (https://www.freenas.org/). That's a linux operating system based on Debian and at least as good for home use.

Golden tip 2, think of your Office365 or Google G Suite environment.

More and more companies have a cloud environment from Microsoft or Google. The promise of the cloud is as if a backup is no longer necessary. It is of course true that the cloud is (almost) never unreachable, but that is no guarantee for human error. If an employee accidentally deletes data, or you are a victim of a hack, you will be relieved when you know you have a backup.

There are several commercial players that provide turnkey backup software for these environments, but it is best not to go for the first hit in Google. Acronis (https://acronis.com/) is a software company with a solid reputation that builds very good backup solutions, both for the cloud and older systems.

Golden tip 3, encrypt the backup

A backup is very sensitive, because it contains all the data of your organization. If your backup is hacked, it has disastrous consequences. That is why it is important that a backup is secured with a strong cryptographic key, especially if you work with an external supplier (e.g. a data center) to succeed in your backup. Good backup software gives you that possibility.

Pay attention to where the encryption takes place, typically you want the data to be encrypted on your local device (e.g. your NAS) with a key that only you and a confidant have. This way even the cloud provider can't know what you're putting on their systems.

There you go, I hope our tips can inspire you to choose for a reliable backup as well. If you're not such a do-it-yourselfer, don't hesitate to inquire about our professional backup service.

Keep it safe!
