The growing amount of high-resolution photos on our smartphones has made cloud storage subscriptions increasingly expensive. Many users, including myself, find themselves paying significant amounts to keep a full backup of their images. However, there is a concrete and free alternative that uses the space already available on your computer. I am talking about Syncthing, an open-source application that synchronizes files between devices without going through third-party servers.
After testing this solution for weeks, I decided to abandon my paid cloud storage tier and rely entirely on Syncthing for full-resolution photo backup. The result is surprising, not only for the cost savings but also for the total control you gain over your data. The setup is straightforward and does not require any particular technical skills.
Installation and initial configuration of Syncthing
The first step is to install the server application on your computer and the client on your smartphone. The process is guided and intuitive. Once installed, the two devices can be paired simply by scanning a QR code. There is no need to create any account, not even a free one, ensuring maximum privacy and no hidden costs. Once connected, you can select the folders to share. I chose the photos folder on my phone and specified a directory on my computer as the destination. From then on, every new photo taken is automatically copied to the local hard drive, without any manual intervention.

Synchronization without network limitations or compression
One of the most appreciated features of Syncthing is its ability to work across different networks. Unlike some tools that require being on the same Wi-Fi network, Syncthing can transfer data over mobile connections or even through a public network. This is particularly useful for travelers who want to ensure that photos taken during a trip are safe without waiting to get home. Moreover, Syncthing does not compress or reduce the quality of images. Every file is copied exactly in its original form, whether it is JPEG, RAW, or video. This is a fundamental advantage for photographers who need intact files for post-processing.

Direct file access and flexible management
Another positive aspect is that synced photos are simply files on your computer, accessible through any file management application. There is no need to open a specific app or website to view them. Additionally, you can configure different synchronization policies for each folder. In my case, for the photo folder, I set it to "send only" mode, so any changes or deletions made on the computer do not reflect on the phone. This allows me to organize the local backup by deleting duplicate or unnecessary photos without risking losing the original files on the mobile device.

Data protection with versioning and trash
Syncthing also offers advanced features for data protection. Through versioning settings, you can keep multiple copies of synced files. I configured a simple versioning system that retains the latest five versions of each file for a period of thirty days. This protects me from accidental deletions or unwanted modifications. If I accidentally delete or overwrite a file, I can easily recover it from Syncthing's virtual trash. This feature is essential for those who, like me, treat their memories with the utmost seriousness.
Limitations and practical advice
Of course, Syncthing does not completely replace all cloud services. It does not offer the same social sharing features or integrated editing. Additionally, it requires the computer to be turned on and connected to the network to receive files. Another aspect to consider is that local backup is not sufficient if you do not make periodic copies to external drives. I recommend connecting an external hard drive and performing regular backups to avoid data loss in case of computer failure. Despite these limitations, the solution has proven extremely effective for my use case, allowing me to save on my Google One subscription and have total control over my files. For those tired of paying for cloud, Syncthing represents a valid alternative.
