Network Attached Storage (NAS) offers a centralized location on a network to store data. Compared to traditional Network Attached Storage, a Synology NAS is a popular choice among business users. It not only offers centralized storage but also allows users to build a private cloud for storing, backing up, and sharing files.

Users often choose the incremental backup method to back up their Synology NAS. This article will provide a comprehensive understanding of the incremental backup process and guide you on how to carry out an incremental backup of your Synology NAS with EaseUS Todo Backup Enterprise.

What is Incremental Backup

Incremental backup is a method that backs up only the files that have changed since the last backup, regardless of whether the previous backup was a full, incremental, or differential backup.

The Advantages and Disadvantages of Incremental Backup

Efficiency: Incremental backups are faster and more efficient than full backups because they only back up data that has changed since the last backup.
Storage Utilization: They use less storage space as they don’t duplicate data.
Bandwidth Usage: They consume less network bandwidth, making them ideal for environments where network bandwidth is a concern.

Longer Restoration: Restoring an incremental backup is typically slower than a full backup because the system must process each incremental backup in sequence.
Risk of Data Loss: If any incremental backups in the sequence are damaged, corrupted, or missing, it could result in incomplete data restoration.
Complexity: Managing incremental backups can be more complex as they depend on previous backups.

How to Perform Synology NAS Incremental Backup FAQs

1. Is Synology Drive backup incremental?

Synology Drive Client supports incremental backups. Following the initial full backup, subsequent backups only capture the changes to files and folders. This is accomplished using approaches like file-level deduplication and version control.

2. Does Synology Hyper backup do incremental backups?

Hyper Backup features block-level incremental backup to back up only the modified/added data chunks of a file after the first-time backup rather than the whole file.

3. What are the pros and cons of incremental backup?

Pros: As it only backs up the changed content from the last backup, Incremental backup is faster when creating a backup, and less storage space is needed.

Cons: It requires the full backup it-based and many sets of the previous incremental backups to fully restore all the data, so that the backup restore process will be slow. And if one of the subsequent backups in the chine is damaged, all the following images based on it will be unavailable.

4. What is the difference between Incremental and Differential backup?

An incremental backup stores all files changed since the last backup, whether it was a full or an incremental backup. This means it takes less storage space and is quicker to perform than a full backup. A differential backup saves all files changed since the last full backup, regardless of other differential backups made in between. So, it takes more space and is slower to perform than an incremental backup.
