Expert Tips: What is backup? Good Data Backup
A RAID hard disk array as a possible backup medium.
Langmeier Backup is a backup program. But what is a backup? And how do I make a backup correctly and professionally? In data processing, the term "backup" is synonymous with "backup copy". But a single copy of a file is not yet a backup, because backup involves more: it is a systematic process. For example, a backup worthy of the name requires at least three copies on different data carriers.
The data carriers on which backups are executed and stored are called backup media.
The sources of error when creating a backup can be very diverse. A full backup medium, a defective drive or a drive with a loose contact; and great is the danger that the "data backup" fails. To reduce this danger, companies are increasingly using two completely independent backup systems. And there is a clearly responsible backup administrator. This is the person in the company who is responsible for the smooth execution of the backups. At regular intervals, this person checks the backup logs, and randomly restores files from backup, thus also practicing the "backup and restore" process on a regular basis.
The 3-2-1 backup rule
In order for a backup to really qualify as a backup, you should follow the 3-2-1 rule when creating a backup.
The rule goes like this:
Today, there are modern technologies that allow you to keep a backup off-site. These are more convenient and secure than the ominous "carry it home in a suitcase". The options range from full server replication, for example via Synology NAS disk stations, to online backup to a third-party cloud.
