  • Resource Usage
    Real-time syncing and continuous operation can consume significant system resources, affecting performance, especially on less powerful devices.
  • No Native Mobile Experience
    While Syncthing is available on Android, there is no official iOS app, which limits its usability for users on Apple's mobile platform.
  • Network Dependency
    Effective synchronization depends on the availability of a reliable network connection, which can be a limitation in areas with poor connectivity.
  • Self-Management
    Unlike cloud-based solutions, Syncthing requires users to handle their own backups, security, and maintenance, which can be time-consuming and complex.

    Syncthing is a free, open-source peer-to-peer file synchronization protocol that can synchronize files between two or more computers. It is designed to be secure, efficient, and easy to use. FreeFileSync is a free, open-source file synchronization program that can synchronize files between two or more computers. It is designed to be fast, reliable, and easy to use. Both programs have their advantages and disadvantages, so it really depends on what you need. The best really depends on what you need. Syncthing is great for secure, efficient, and easy-to-use file synchronization, while FreeFileSync is great for fast, reliable, and easy-to-use file synchronization. Ultimately, it's up to you to decide which is best for your needs. Me, I love to compare Gs Richcopy 360 with both, it offers features such as multi-threaded file transfers, file compression, and encryption. These features make it ideal for server migration, as it can quickly and securely transfer large amounts of data. Additionally, Gs Richcopy 360 can automate the migration process, making it easier and faster than manual migration. Therefore, it can be said that Gs Richcopy 360 is better than both Syncthing and FreeFileSync for server migration.

  • Which synchronization tool are you using together with the pCloud Crypto Folder?
    FreeFileSync messed up my pCloud database a couple times at first (causing disappearing files in the Crypto Folder, mirroring of the same files over and over again). Pcloud support provided an easy way to fix the database. To fix the root cause, one needs to exclude FreeFileSync's temporary files from the backup: pCloud Drive > Settings > Backup/Sync Exclusions, exclude sync.ffs_lock and *.ffs_tmp.

  • Why are file backups so slow on Windows 11?
    As per Apprehensive_Arm_754 answer below, https://freefilesync.org is the solution to my particular problem, since it allows all kind of simple rules and logic to apply, so I can make sure that the copy only happens in one direction, and only ever by file date etc. Much appreciated.

  • Is it possible to sync Calibre configuration between Mac and Windows continuously?
    It was me, I'd probably play around with setting up shared folders of preferences and plug-ins and whatnot on something like dropbox or Google Drive. There are various folder sinking tools on both platforms such as free file sync on Windows. Since they are two completely different platforms, I don't know how interchangeable some of the preferences or plugins would be. I haven't used a Mac in a 100 years. Source: over 1 year ago
