Database Backup Size Calculator

Estimate the size of your database backups for Oracle, SQL Server, PostgreSQL, and SAP HANA. Understand the different backup types and their use cases to optimize your backup strategy.

Backup Types Explained

Oracle Backups

• RMAN Full Backup: A complete backup of the entire database, including all data files, control files, and archived redo logs. Ideal for full database recovery.
• Incremental Backup: Backs up only the data that has changed since the last backup. Saves storage space and reduces backup time.
• Data Pump Export: Exports database objects (tables, schemas, or entire databases) into a binary file. Useful for logical backups and migrations.

SQL Server Backups

• Full Backup: Backs up the entire database, including all data and log files. Essential for complete recovery.
• Incremental Backup: Captures only the changes made since the last full or incremental backup. Reduces backup size and time.
• Transaction Log Backup: Backs up the transaction log to allow point-in-time recovery. Critical for databases in full recovery mode.

PostgreSQL Backups

• Base Backup: A physical backup of the entire database cluster. Used as a starting point for WAL (Write-Ahead Logging) archiving.
• Export (pg_dump): A logical backup that exports database objects into a SQL script or custom-format file. Ideal for migrations and logical backups.

SAP HANA Backups

• Full Backup: Backs up the entire database, including data and log volumes. Essential for disaster recovery.
• Incremental Backup: Captures only the changes since the last full or incremental backup. Reduces backup time and storage requirements.
• Export: Exports database objects into a file for logical backups or migrations.
