Data backup and document disaster recovery are important aspects of data management and protection. They include creating copies of important data to prevent data loss in the event of unforeseen events or accidents. Here is a complete overview of these topics.
Data backup includes creating duplicates of your documents, databases, applications and other important data to protect them from accidental deletion, hardware failures, cyberattacks or natural disasters. The main purpose of data backup is to ensure data availability and facilitate recovery in case of data loss.
Full backup. A full backup includes copying all data from the source to the backup storage. It provides a complete snapshot of the data, but can be time consuming and require significant storage space.
Incremental backup. An incremental backup only copies data that has changed or been created since the last backup, reducing backup time and storage requirements. However, the restore process may include multiple incremental backups.
Differential backup: Differential backup copies all the data that has changed since the last full backup. This requires more storage space than an incremental backup, but simplifies the restore process.
CDP automatically and continuously backs up data as changes are made, providing near real-time restore points.
Snapshot technology captures the state of the system at a certain moment, which allows you to quickly restore it in case of problems.
Store backups on external drives, network attached storage (NAS), or physical tapes in the same location as the original data.
