Computers are a common part of personal and professional life. When working on a computer, the user produces data in the form of ones and zeros. The data is stored on disk in the form of files and nothing more is taken care of. However, these are files that have given the user a lot of work, often taking many hours to create, and are not available anywhere else. Then, when the Windows operating system crashes, an external drive drops and breaks while traveling, or the user accidentally deletes the data, all the tedious work is gone. To avoid losing your work you need to back it up! How to back up? Find out what your backup options are in this article.

Current backup status

From a backup perspective, computer users can be divided into three groups:

  1. Don't back up
  2. Backup
  3. They are able to restore data from backups
Checking the ability to restore data is necessary so that efforts to restore data do not end up like GitLab company that failed all backup methods.

How to backup

A lay user usually just needs to have a dedicated disk, for example, that they use exclusively for backups. He manually copies files he doesn't want to lose to this disk once in a while.

For quality backup and streamline your work, however, it's better to use a tool. For example,

Rsync

, which is used to synchronize data. Using it, you can easily solve automatic copying. This eliminates manual work and you cannot forget a file. At the same time, the program is fast because it only copies changed files.

A more advanced option are tools that also keep backup history, such as rdiff-backup.
Or you can use tools that store backups on the server. With such a solution, the data is also separated physically and the backups are then separated from any problems on the work computer.

With state-of-the-art file-systems such as BTRFS, you can take backup even further. You can back up very frequently - in no time at all.
It is possible to combine BTRFS with rsync or another tool.
My favorite option is to use BTRFS to automatically backup the complete computer when it starts up. By using BTRFS, I have all my creation history from each day and it is easily accessible.

In the case of Windows, it is preferable to store data on a network drive that is on a server on the local network, and to provide backups on the server. This solves two birds with one stone, both storing and remotely accessing the data and backing it up.

There are many backup options, depending on your specific needs and devices. That's why you always need to address customized backup to your solution.

Data Security

Backups are needed not only because there may be a problem on the hardware side or due to user error, but if well designed, backups also keep data safe from attack. A typical problem is when an individual or company is attacked by ransomware and loses their current work data and copies of it.

Backups should be automated, simple to use and securely segregated. For example, my pre-made snapbackup service, simplicity and security delivers.
