BitTorrent has joined the cloud services race with a new service called Sync, which aims to provide safe and private cloud backup.

Today's tech-driven world is no short of means to transfer files from one PC to another, but BitTorrent's offering has some key differences that make it stand out. For instance, with Sync, users will actually be using BitTorrent's servers to transfer files from one device to another.

Using BitTorrent's servers brings several benefits, including the fact that users no longer have to face the size restrictions imposed by other services such as Dropbox and SkyDrive. Dropbox, for instance, offers 2GB of free storage space, but trying to sync multiple videos at once will rapidly hit that cap. Any additional space will cost.

The new BitTorrent Sync service unveiled is currently a rough, pre-alpha version, and is part of the company's efforts to develop new technology called BitTorrent Labs.

"We like it when things work together. So we've been working on a new distributed syncing product to help manage personal files between multiple computers," the company explained in a blog post announcing the new service.

"Today, BitTorrent Sync is in a pre-Alpha stage. And we're hoping that users like you can help us build something sick. If you're comfortable using early, incomplete software, and if you're committed to helping us figure out a better way to sync, we want to hear from you."

For now, those interested have to fill out an application and wait for a response before being able to use the service. The application form has numerous questions, including how many computers the service will be working on, which operating system will be in use with Sync, etc.

BitTorrent's Sync is free to use, and places no limits on the amount one can transfer from one device to another. Those who are not willing to try out pre-alpha testing, however, will have to wait a bit longer before the service becomes available. Sync should be ready for BitTorrent users in a few months.

BitTorrent also has other experimental services, such as BitTorrent Live for live-streaming, and BitTorrent Surf for making a torrent client out of Google Chrome. Sync joins the lineup on the cloud front.
