CTERA Networks is a cloud storage and data protection hardware and software company that specializes in cloud storage gateways. It provides network storage combined with asynchronously replicated off-site cloud storage.[1][2] The company produces hardware appliances which are installed in the local network and backup data offsite, and management software for service providers.
CTERA markets cloud storage gateways that use traditional file-based protocols to provide cached cloud storage. Local network computers are automatically backed up to the CTERA appliances on the LAN, which then perform incremental backups to an off-site deduplicated cloud storage service, compressing and encrypting the data as it is transmitted. Users have browser-based access to the backups and can access files locally using a "Virtual Cloud Drive”.[2] Users can also throttle bandwidth and schedule transfers off working hours for reducing impact on the network performance.[3] CTERA appliances encrypt data onsite and keep the keys local, reduce latency by caching data or keeping local copies, and provide snapshot capabilities for data availability.[4]
CTERA is also the developer of Next3, an open source journaled file system for Linux.[5]

CTERA, based in Palo Alto, California and Israel, was founded in 2008.[6] The company is privately held and backed by Benchmark Capital.[7][8][9][10]
In 2010, a new local NAS appliance was unveiled that can be used for bare metal recovery of downed servers. New server agents were also introduced to make backup and recovery easier and enable multi-user collaboration on files or folders stored locally or in the cloud. [12]
In 2011, the company was named a "Champion" by the Info-Tech Research Group.[10]
CTERA has partnered with EMC Atmos, Rackspace and storage providers like Scality and ComputerLinks.[13][14][15]
CTERA Networks produces the CloudPlug, a small form factor Plug computer that converts external hard drives into network attached storage combined with cloud backup.[11][16][5] It also makes several appliances (C800, C400 and C200), which are installed in the local network and backup data into the cloud. CTERA devices can be used for hybrid on-site and offside data protection using cloud backup, snapshots and bare-metal restore capabilities.[17][1][7][18][19][20]
In addition to "clientless backup" capabilities, the company provides an installable backup agent that can back up open files,[21] and server agents for backup and recovery of Microsoft Windows server applications, such as Microsoft Exchange Server, Microsoft SQL Server and Active Directory.[22]
CTERA has developed Next3, an open source journaled file system for Linux based on ext3, which adds snapshots support, yet retains compatibility to the ext3 on-disk format.[5][23] Next3 is implemented as open-source software, licensed under the GPL license.[1] Next3 uses dynamically provisioned snapshots, i.e., it does not require pre-allocation of storage space for snapshots. Instead it allocates space as needed. Storage space is conserved by sharing unchanged data among the file system and its snapshots.[24]
