Forever Forward Incremental (FFI) is a Veeam backup processing mode that combines the efficiency of incremental backups with the retention benefits of full backups. With FFI, only the delta changes between full backups are backed up, which significantly reduces backup windows and storage requirements. However, unlike incremental backups, FFI retains all full backups indefinitely, ensuring that you can restore to any point in time.
FFI is a good option for organizations that need to balance the need for efficient backups with the requirement to retain historical data for long periods. It is particularly well-suited for organizations that need to comply with data retention regulations or that have mission-critical applications that cannot afford downtime.
Here are some of the key benefits of using FFI:
- Reduced backup windows and storage requirements: FFI only backs up the delta changes between full backups, which can significantly reduce backup windows and storage requirements.
- Retains all full backups indefinitely: Unlike incremental backups, FFI retains all full backups indefinitely, ensuring that you can restore to any point in time.
- Provides protection against ransomware: FFI can help to protect against ransomware attacks by providing a chain of backups that can be used to restore data to a point before the attack occurred.
- Easy to manage: FFI is easy to manage and configure, and it can be integrated with other Veeam backup features, such as replication and backup copy jobs.
Overall, FFI is a powerful and flexible backup processing mode that can help organizations to achieve their data protection goals. If you are looking for a way to improve your backup efficiency and retention, FFI is worth considering.

Reverse incremental backup is a type of incremental backup that backs up only the changes that have occurred since the last full backup. This type of backup is often used when there is a lot of data to back up, as it can be significantly faster than backing up the entire dataset every time.
Reverse incremental backups are based on the concept of change tracking. This means that Veeam keeps track of the changes that have occurred to the data since the last backup. When a new backup is created, only the changed blocks of data are backed up. This can significantly reduce the amount of time it takes to create a backup, especially if there is a lot of data to back up.
Reverse incremental backups are also efficient in terms of storage space. This is because only the changed blocks of data are stored in the backup repository. This can save a significant amount of storage space, especially if there are frequent backups.
Here are some of the benefits of using reverse incremental backups:
- Faster backup times: Reverse incremental backups are typically faster than traditional full and differential backups, as they only back up the changes that have occurred since the last backup.
- Efficient storage: Reverse incremental backups are more efficient in terms of storage space than traditional full and differential backups, as only the changed blocks of data are stored in the backup repository.
- Reduced storage costs: The reduced storage requirements of reverse incremental backups can lead to lower storage costs.
- Simplified backup management: Reverse incremental backups can simplify backup management, as you only need to create a full backup every once in a while, and then create reverse incremental backups on a regular basis.
Here are some of the drawbacks of using reverse incremental backups:
- More complex backup process: Reverse incremental backups are slightly more complex to implement than traditional full and differential backups.
- Increased storage overhead: Reverse incremental backups require some additional storage space for the change tracking metadata.
- Potential for data loss: If the backup repository becomes corrupted, it may be possible to recover only the data that has changed since the last full backup.
Overall, reverse incremental backups are a powerful and efficient way to back up your data. However, it is important to weigh the benefits and drawbacks of this type of backup before implementing it.
