Types of Database Backups

There are several types of database backups available, each serving a different purpose:

1. Full Backup: A full backup includes a copy of all data in the database and is typically used as a baseline for other types of backups. It provides a complete snapshot of the database at a specific point in time.
2. Incremental Backup: Incremental backups only contain data that has changed since the last backup. These backups are faster and require less storage space compared to full backups. They are useful for regular backups to capture changes made since the last backup.
3. Differential Backup: A differential backup includes all changes made since the last full backup. This type of backup is faster than a full backup and requires less storage space compared to incremental backups. It is useful for capturing changes since the last full backup.
4. Transaction Log Backup: Transaction log backups capture all transactions that have occurred since the last log backup. These backups are essential for point-in-time recovery and maintaining data integrity in case of a failure.
5. Copy-Only Backup: A copy-only backup is a snapshot of the database taken without affecting the backup and restore procedures. It is useful for creating backups for specific purposes without disrupting the regular backup schedule.

Each type of backup has its own use case based on data protection requirements, recovery objectives, and storage considerations.
