Arcade game machines, especially vintage or retro ones, rely heavily on data integrity to function correctly. To prevent data loss and ensure smooth gameplay, various backup systems are employed. Here are the most common types:

1. ROM Cartridges: Many arcade games store data on ROM (Read-Only Memory) cartridges, which can be swapped or duplicated to preserve game data.

2. Hard Disk Drives (HDD): Modern arcade machines often use HDDs for storing game data, allowing for larger storage capacity and easier backups.

3. Solid-State Drives (SSD): Faster and more reliable than HDDs, SSDs are becoming popular for arcade backups due to their durability.

4. Flash Memory: Some systems use flash memory cards or USB drives for quick and portable backups.

5. Cloud Storage: Advanced arcade setups may backup data to cloud services, ensuring remote access and redundancy.

Regular backups are essential to protect against hardware failures, corruption, or accidental deletions, keeping the arcade experience alive for years to come.
