Ever since the dawn of smartphones we have faced a problem, how to sync those documents and images from our computer to our phone (Unless you are content with emailing yourself those endless list of files)? There were solutions of course: MTP, Nokia came with Ovi Suite, Samsung has the dreaded Kies and services like Dropbox, Google Drive, OneDrive etc too have given a shot at solving this problem. Online services do come close, but you need to upload and download data to and from a central server over the internet and we all know about the nightmare inducing driver issues of wired solutions. This is where BitTorrent Sync by BitTorrent(duh) comes to rescue.
You might have heard of the BitTorrent brand, while almost all ‘biggies’ are busy devouring every bit of personal information for targeted advertising and more, this lot has focused on building privacy focused, decentralised apps.
Getting back to the app, BitTorrent Sync (BTS) is actually far from disappointing. Simply put, BitTorrent Sync provides a way to sync files between your different devices, or selectively share files and folders with different people. It will work across your LAN and even across the world! It is a Dropbox-like-syncing without the Dropbox. You simply set it up (getting to that in a bit) and it monitors your folders and syncs your files over LAN. No fuss, no need to plug-in cables or worry about file size limitations, transfer limits or missing drivers.
Setting BTS up is pretty easy, in simple words: you select a folder and generate a key on one device… and then select a folder and enter the secure key on other device. It works in the background and keeps the two folders in sync. While setting up the folders you have two options: full access or read only access.
Full access essentially means a two-way sync, both devices have the same files always, both can make changes. Read only sync means a one way sync, primary device (‘from’ device) can make changes and the secondary device or ‘to’ device can read the files (and edit but changes are not synced back to the primary device).
There is not much that needs fiddling with in the settings.
- You can rename the device.
- Enable syncing over mobile data(be careful!)
- Allow notification, to let service run properly in background.
- Enable auto-start, letting the application start as soon as your device boots up.
- Auto sleep: Enables the battery friendly mode, the application checks for new files only once in every 15 mins – 4 hours(you pick).
- Backup/Restore Sync settings – exactly what it sounds like.
Now if you haven’t noticed, one major drawback of this app is that you need a computer to set up folders, but then you can share them to other mobile devices.
Privacy focused, file transfers are encrypted and protected by secure keys, your data is never stored on a server in the cloud, supports almost all major platforms, no file size or transfer limitations.
Needs a computer to set up folders(can't set up just two devices but can sync).
