Best Practices for Cloud Storage Syncing Solutions

When designing a syncing solution for cloud storage, consider the following:

• Use incremental uploads to reduce bandwidth.
• Implement conflict resolution based on timestamps and user roles.
• Encrypt data both at rest and in transit.
• Provide clear UI feedback for sync status.

What are your experiences with handling large file sets?

We've found that chunked uploads combined with retry logic greatly improve reliability on flaky connections.

Also, a local change queue helps keep the UI responsive while syncing in the background.

Don't forget about device-specific throttling. Mobile devices should sync less aggressively to preserve battery.

Here's a small script we use to adjust sync intervals based on power source:

if (navigator.getBattery) {
  navigator.getBattery().then(b => {
    syncInterval = b.charging ? 30000 : 120000;
  });
}
