When it comes to data protection and disaster recovery, a well-structured backup retention policy is crucial. MSP360 Managed Backup offers a range of options to help businesses ensure their data is backed up and stored effectively.
Learn everything you need to know about backup retention policies
Backup retention policies play a crucial role in managing and securing your data. As an MSP or IT administrator using MSP360, understanding when and how to implement specific backup retention policies like Grandfather-Father-Son (GFS) or Forever Forward Incremental (FFI) can significantly impact your data management strategy. In this blog post, we'll dive into the basics of backup retention policies.
Understanding Backup Retention Policies
Before diving into specific backup retention policies, it’s essential to understand what retention policies are. Retention policies determine how long your data is kept before being deleted or overwritten. This ensures that your backups are manageable, storage costs are controlled, and compliance requirements are met. Without a proper backup retention policy, you risk retaining unnecessary data, which can lead to increased costs and management challenges.
Types of Backup Retention Policies
- Base Backup Retention: Retains backups for a specific period. For example, you can keep daily backups for 30 days, weekly backups for 6 months, and monthly backups for a year.
- GFS (Grandfather-Father-Son) Backup Retention: GFS works as an addition to the base retention and combines weekly, monthly, and yearly backups to create a comprehensive backup strategy. Weekly backups are retained for a month, monthly backups for a year, and yearly backups indefinitely.
- Forever Forward Incremental Backup Retention: this approach involves creating the initial full backup, followed by a set of subsequent incremental backups. Unlike the traditional approach, which requires multiple full backups, the FFI approach creates only one full backup, which saves storage space and a significant amount of money and ensures quicker backup times.

1. What is a Base Backup Retention Policy?
A base backup retention policy defines how long your backup data is retained before it is automatically deleted. This policy allows you to specify the retention period for your backups based on days, weeks, months, or years.
Benefits of Base Retention
- Storage Optimization: Automatically deleting old backups helps manage storage costs and prevents unnecessary data accumulation.
- Regulatory Compliance: Helps meet legal and regulatory requirements for data retention periods.
- Simplified Data Management: Automates the cleanup of outdated backups, reducing administrative overhead.
- Enhanced Performance: By keeping only relevant data, you can improve the performance of your backup and recovery processes.
By setting a time limit, you can ensure that outdated data is removed, optimize storage usage, and ensure compliance with data retention regulations.
2. What is the Grandfather-Father-Son (GFS) Backup Retention Policy?
The Grandfather-Father-Son (GFS) retention policy is a hierarchical backup strategy designed to provide a balance between long-term and short-term data storage. GFS is a widely used retention policy designed to ensure data integrity and efficient storage management. MSP360 Backup offers the GFS retention policy to help businesses maintain a comprehensive and organized backup system.
Here’s how it works:
- Son (Weekly Backups): These are your weekly backups, typically retained for a month.
- Father (Monthly Backups): A backup from the “Son” category is promoted to the “Father” category and is retained for a year.
- Grandfather (Yearly Backups): One of the “Father” backups is promoted to the “Grandfather” category and is retained for several years or longer.
When to Use GFS
- Regulatory Compliance: If your organization must comply with data retention regulations that require keeping data for extended periods, GFS is ideal. It ensures that you have backups spanning several years.
- Historical Data Analysis: Organizations that need to analyze historical data trends over months or years can benefit from the GFS policy. It retains significant historical data without requiring daily or weekly backups to be kept long-term.
- Disaster Recovery Planning: GFS provides multiple recovery points, ensuring that you have numerous options to restore data in case of a disaster.
For example, that's how GFS might look with only monthly full and 30 incremental backups
Implementing a GFS retention policy with MSP360 Backup can be essential for a comprehensive data protection and efficient storage management strategy. By understanding and configuring GFS, you can ensure your data is stored efficiently, complies with legal requirements, and is always available when needed. Don't forget to regularly review and adjust your policies to align with your evolving business needs and optimize your backup strategy.

3. What is the Forever Forward Incremental Backup Retention Policy?
Forever Forward Incremental (FFI) is a backup strategy that starts with a full backup and then only backs up changes made since the last backup (incremental backups). Unlike traditional incremental backups that periodically require a new full backup, FFI continually appends changes to the initial full backup. This method saves storage space and reduces the time needed for backups. MSP360 Backup offers this strategy to ensure continuous data protection while minimizing storage use and backup times.
When to Use Forever Forward Incremental
- Storage Efficiency: If minimizing storage usage is a priority, this policy is beneficial. Only changes since the last backup are stored, significantly reducing the amount of storage needed.
- Fast Backups: Incremental backups are faster than full backups. This policy is suitable for environments where minimizing the backup window is critical.
- Frequent Backup Requirements: Organizations that require frequent backups (e.g., daily or even multiple times a day) will find this policy useful because it reduces the time and storage required for each backup.
For example, that's how FFI works with AWS Standard Tier with a 30-day retention period
Implementing a Forever Forward Incremental backup retention policy with MSP360 Managed Backup is essential for efficient data protection and storage management. By understanding and configuring FFI, you can ensure your data is backed up continuously, storage usage is optimized, and the backup process is streamlined. Regularly review and adjust your policies to align with your evolving business needs and to optimize your backup strategy.

Best Practices for Implementing Backup Retention Policies
- Assess Your Needs: Evaluate your organization’s specific requirements, including compliance, data recovery objectives, and storage capabilities. This assessment will guide you in selecting the most appropriate retention policy.
- Combine Policies: In many cases, a combination of GFS and Forever Forward Incremental policies can offer the best of both worlds. For example, use Forever Forward Incremental for daily backups and GFS for long-term retention.
- Regularly Review and Adjust: Periodically review your retention policies to ensure they still meet your organization’s needs. As your business evolves, your data retention requirements may change.
- Automate and Monitor: Utilize MSP360’s automation capabilities to enforce retention policies consistently. Regular monitoring ensures that policies are being followed and storage is being managed effectively.
- Test Your Backups: Regularly test your backups to ensure data can be restored as expected. Testing helps identify any issues with your retention strategy and allows you to make necessary adjustments.
