Backup is a term used to describe a safety copy that can be used to copy back or restore data in the event of a system failure or data loss. The copy can be created on an external hard drive, the computer’s hard drive or even on a USB stick. The data can also be saved online.
The answer is simple – for two reasons:
The most important backup is the one you didn’t make!
The amount of your personal data increases significantly over the years. As already described at the introduction, this is all data, such as for example family pictures, documents, e-mails, etc.
All data is stored on your computer – more precisely, on your hard disk. This storage medium holds your data and on it you can store, retrieve and edit other data. Modern technology is very advanced and durable, but not immortal.
The technical equipment, such as the hard disk, lives a certain number of operating hours. Depending on use and stress, this can be longer or shorter. At some point, however, malfunctions and defects will consequently occur due to wear and tear. In exceptional cases, even a new hard disk (in principle, this applies to any storage device) can become defective. The consequences are that your computer cannot be started, you no longer have access to your data and, in the worst case, the data is lost due to a defect. It can also be caused by malware, such as a computer virus or ransomware preventing you from accessing your data or intentionally deleting it.
Therefore, it is very important that your data is at least duplicated and independent on different storage media. This means that you do not store any backup on the same hard drive, because the data backup itself can also be lost due to a defect. Here, physical separation is very important – that is, an extra storage medium, such as a separate hard disk.
You need to decide how often you should perform a data backup. It depends on the frequency, how often you change your data. With a manual backup, it also requires a certain discipline to perform it regularly yourself or have it performed by backup programs
With a full backup, all the data to be backed up is saved in one backup file on the target disk each time. As a result, all backed up data is contained in only one file, which simplifies backup management.
+ Backup creation or restoration is faster than differential or incremental backup.
+ It is easier to manage because only one file is needed for a restore.
– A regularly performed full backup requires more storage capacity than a differential or incremental backup.
In a differential backup, only the data that has changed or been added since the last full backup is backed up. Such a backup therefore requires a previously created full backup. For a restore, both files, i.e. the basic full backup and the differential backup file, are required.
+ A regularly performed differential backup requires less storage capacity than a full backup.
– A restore of the backup is slower than that of the full backup.
– Handling is more complicated, because two files are needed for a restore.
An incremental backup also only backs up the data that has changed since the last backup and any new data that has been added. This backup method also requires a previously created full backup. Unlike differential backup, however, incremental backup is always based on the previously created backup and only on the full backup during the first run.
+ A regularly performed incremental backup requires less storage capacity than a full backup or differential backup.
– A backup restore is slower than that of the full or differential backup.
– The handling is more complicated, because all files of the “backup chain” are needed for a restore.
