Synthetic Backup


Synthetic backup is a data protection method that combines a full data backup with subsequent incremental backups to create a complete, updated version of the data. It reduces the amount of time and resources to execute a full backup every time by merging the most recent full backup with any changes or additions made since the last backup. This way, it eliminates the need for backup windows, provides quicker backups, and minimizes the impact on system resources.


The phonetic spelling of “Synthetic Backup” is: Sin-thet-ik Bak-uhp

Key Takeaways

  1. Synthetic Backup Consolidates Data: One of the main benefits of synthetic backup is that it consolidates full and incremental backups into a single, master backup. This reduces the dependency on older archives and lessens the need for continuous full backups, saving both time and storage space.
  2. Improved Recovery Time: Since synthetic backup combines all incremental copies into a full backup, it allows for a faster recovery time in case of data loss or corruption. Instead of restoring a full backup and every subsequent incremental backup, you can restore a synthetic backup, which significantly improves disaster recovery efficiency.
  3. Less Interruption to Systems: Synthetic backup can be created without needing to interrupt or put a heavy load on production systems. As a result, it imposes less impact on business operations compared to traditional backup solutions, making it a more efficient and work-friendly alternative.


A synthetic backup is an important concept in technology because it streamlines and optimizes the data backup process. Instead of performing a time-consuming full backup, synthetic backup merges an initial full backup with subsequent incremental backups to create a more recent full backup. This not only minimizes the workload and storage space but also significantly reduces the impact on the devices and networks, making the backup and recovery process more efficient. Furthermore, it provides a full restore point that is accurate and up-to-date, which makes it an essential tool for comprehensive data protection and recovery planning.


Synthetic backup serves as an efficient method of data protection, primarily used to reduce the time and resources spent on performing full backups. It is a process that consolidates a full backup and subsequent incremental backups into a single file, essentially ‘synthesizing’ a full backup version from existing data. This technology is used to improve backup speed and data reliability while reducing the impact on network resources and system performance, and avoiding the need for a full system backup.By consolidating full and incremental backups, synthetic backup enables faster recovery in the event of data loss, as data recovery is performed from a single, up-to-date backup file. It reduces the volume of historical backups required, improves storage efficiency, and ensures minimum business disruption during backup operations. This makes it a valuable tool for businesses that need quick recovery time objectives and efficient backup operations, or where networks are constrained by bandwidth or performance issues.


1. Enterprise Data Backup: Large corporations and businesses often use synthetic backup to ensure their data is protected and backed up regularly. This technology helps them merge incremental backups with a full backup, allowing them to save storage space and reduce the time required for backup operations. For example, a major enterprise like Amazon or Google may utilize synthetic backup for their huge databases, merging incremental data changes with their original, larger data set thus creating a full, updated backup without needing to backup all data entirely each time.2. Healthcare Industry: In healthcare, patient data and medical records are critical and require efficient backup solutions. Synthetic backup can be employed in this sector to compile and create a full backup of such records by adding recent changes to an existing full backup. For instance, a hospital’s database that regularly adds new patient records or updates existing ones, could use synthetic backup technology to reduce the backup time and ensure quick data recovery during emergencies.3. Cloud Storage Services: Many cloud storage services like Dropbox, Google Drive or iCloud can employ synthetic backup for their customer’s data. Users regularly add, change, and delete files. The synthetic backup method facilitates having updated copies of files available by merging these changes with the existing full backup files. This not only ensures data protection and quick recovery but also saves on storage and processing power.

Frequently Asked Questions(FAQ)

**Q: What is a Synthetic Backup?**A: Synthetic backup is a process of combining a full data backup with subsequent incremental backups to create a more current backup. This eliminates the need for a traditional, time-consuming full backup.**Q: How does Synthetic Backup work?**A: Synthetic backup works by taking a single full backup and then combining it with a series of incremental backups. This essentially synthesizes a full backup without the need to transfer large amounts of data from the backup client.**Q: What are the advantages of Synthetic Backup?**A: Some advantages of synthetic backup include reduced network traffic, faster recovery times, less storage space used, and an increased backup frequency, as you’re able to “create” more frequent full backups without impacting production systems.**Q: Are there any disadvantages to Synthetic Backup?**A: There might be potential challenges including the need for more advanced technology and tools to perform synthetic backups, potential difficulties in managing segmented data, and more time might be needed to consolidate and create a synthetic full backup.**Q: When should I use a Synthetic Backup?**A: Synthetic backup becomes very useful when dealing with large amounts of data that wouldn’t be efficient or practical to perform a traditional full backup on a regular basis. They are ideal for businesses that can’t afford long periods of downtime or window for backup.**Q: How does Synthetic Backup help in reducing network traffic?**A: Synthetic backups reduce the need to transfer data from the primary location to the backup location. This reduces the load on the network, as only incremental changes are transferred, not the entire data set.**Q: Is Synthetic Backup safe and reliable?**A: Yes, synthetic backup is safe and reliable. They provide the same level of data protection as traditional backup methods but with greater efficiency. However, like with any backup process, it should be properly managed and consistently monitored.**Q: Can I use Synthetic Backup for cloud storage?**A: Yes. In fact, synthetic backup is a popular backup strategy for the cloud due to its efficiency in dealing with large data sets and minimizing data transfer which can lead to potential cost savings.
