Up-to-date immutable data backup
Backup is the most important thing for your viability. It is vital to know that your backup works 100% and that the correct data is saved with sufficient history. Encryption of the data is essential, because you do not want your backups to be seen by third parties, for example, in the event of theft. Backup copies that can be accessed quickly and completely in the event of data loss must be created for all business data. Protection is only guaranteed if a backup is decoupled from the company network and physically stored in an external location. So, if you regularly store your data on an external storage medium and then store this in a location other than the office, you are already doing a lot right.
