If Symform doesn't provide the storage, why do they charge at all? Because the control system that keeps tabs on your data requires some hefty computes and storage as well as serious redundancy. To speed uploads you can make copies of your data, move it to different upload sites, and run them in parallel, letting Symform deduplicate already stored blocks. By using a hash of the data block's content, the system can see if a block is already stored online and avoid uploading it again. Data deduplication - all the rage in the enterprise world - is standard as well. Since the data lives on thousands of computers restores happen in parallel across thousands of Internet connections, making reconstruction much faster than relying on a single shared datacenter link. With this system fully one third of the drives can be down and your data will still be recoverable. With RAID 5 one disk failure and then a single unrecoverable read error during data reconstruction wipes out your data. This level of erasure coding goes way beyond what RAID 5 offers.

That's why to get 100 GB of free online storage, you have to offer 150 GB - 50% more - of your own local storage.

The software takes your data, breaks it into 64 MB blocks, encrypts each block with AES-256 encryption, using a hash of the block as the encryption key, and then shards the encrypted block into as many as 96 pieces, where each piece includes an additional 50% of erasure coding replication data. Using Symform's client software and user account you put that file into your local Symform backup folder. To recover a file the system only needs to see the data from 2/3rds of the drives to reconstruct your file. In Symform's much more resilient version your 100GB could be spread across as many as 150,000 disk drives around the world, instead of five or six. The technology uses an advanced form of erasure coding, used in a simpler and less robust form in today's RAID 5 systems. Just put a folder alias on your desktop and you have a way cheaper Dropbox replacement. Not completely free, but you'll never see a better deal for online storage.
#10GB CLOUD STORAGE FREE PLUS#
To get that free 100 GB, all you have to do is donate 150 GB of your unused disk space.Īt five cents per gigabyte - less if you buy a new 2 or 3 TB USB drives - that free 100 GB will cost you $7.50 plus negligible power costs, forever. I spoke to the ex-Microsofties, Parerit Garg and Bassam Tabbara, who founded Symform on a simple premise: the world's cheapest data storage is sitting unused inside your computer or on external USB disks.
