Key Concepts

Archive Bit

The archive bit is a file attribute used by certain backup systems to indicate whether a file has been modified since its last backup. When backing up, systems check this bit to decide which files need to be included, and, in the case of incremental backups, it is reset or cleared after the file is successfully backed up. This mechanism helps simplify the process of identifying new or changed files for backup operations.

Incremental Backup

An incremental backup involves copying only the files that have changed since the last backup, whether it was a full or another incremental backup. A key aspect of many incremental backup systems is that they clear the archive bit after backing up a file, marking it as already backed up. This method can significantly reduce the amount of data transferred and stored, but requires all previous incremental backups for a complete restoration.

Backup Strategies

Backup strategies refer to the various methods used to save copies of data to protect against loss due to failures, disasters, or corruption. This field includes approaches such as full backups, incremental backups, and differential backups, each differing in the amount of data copied and the method of tracking changes. Effective backup strategies are chosen based on needs like recovery speed, data change frequency, and storage capacity.
