Data backup and recovery systems
Data backup and recovery systems are an integral part of any computer infrastructure. They allow you to save valuable data, protect against loss or damage, and also provide the ability to quickly restore information in case of system failures.
The main task of backup systems is to create exact duplicates of all files and settings of the operating system for later use in emergency situations. This may be a hard disk failure, a security threat (hacker attack), user errors, or other force majeure circumstances.
Depending on the requirements of the organization, various backup methods can be used:
1. Full: all data is written to the medium once.
2. Incremental: only changed information is added to the entire previous database.
3. Differentiated: new versions of the file replace the old one every time during the backup procedure.
4. Network/remote: performing backups via a local network or remotely via the Internet.
Data recovery systems allow you to quickly and efficiently restore the system to work after a failure. They can be both hardware (in the event of a hard disk failure, for example), and software (in the event of an operating system error or file loss).
Important characteristics when choosing backup systems:
1. Reliability: the ability to create reliable backups without losing information.
2. Speed: the time for performing backup/restore procedures should be minimal to ensure the performance of computer systems.
3. Flexibility: setting up scheduled automatic backups, choosing endpoints for saved data, defining user access rules.
4. Scalability: the ability to be used not only on a separate PC or server, but also in the corporate infrastructure of entire representations
