I’ve not had files get corrupted, that’s strange, for sure.

Some options (but it really depends on what you’re trying to do):

Resilio Sync (cross-platform, battery eater on mobile, but has a useful feature - Selective Sync)

FolderSync on Android (can also be battery intense)

Native tools and scheduling on Linux and Windows.

Maybe a review of the setup is in order, what your devices are, what you’re trying to do. Sync may not be the tool for what you’re trying to do.

I use a combination of tools for different jobs and devices.

Generally, all files on mobile are synced to home using Syncthing-Fork. For example, on Android I have a sync job(“folder”) in ST for every root folder on the device. These get synced to home depending on conditions (e.g. DCIM syncs over any network, any power condition, so I don’t lose photos, while Backups and Download only sync on power over wifi, since they’re big and not critical).

Between desktop OS’s I largely use OS-specific tools, because I don’t really need sync there, but file copy and comparison on a schedule.

After 10 years and probably 1TB+ of sync, I haven’t lost any files via ST. Currently have 5 phones running jobs back to a server. I’ve even moved Syncthing from one server to another with no issues. With how ST works, I think file corruption is highly unlikely - it even handles in-use files safely.
