SpiderOak is a file hosting - service . A software called SpiderOak One for Windows , macOS , Linux , Android and iOS is available for synchronizing files . You can use it to back up the user's data and share individual folders or files with other people or synchronize them on different systems. The focus here is on the privacy of the user.
Functions
Data backup plays the central role at SpiderOak. Here, the user has the option of building on his existing folder structure by defining which file types (text, audio, video ...), folders or files he would like to back up. This means that the files do not need to be stored in a specific folder, but can be backed up from their regular storage location.
Since the data is not only stored in the cloud , but also on a computer, you can use your documents without internet access. These are then backed up with the next connection. To save storage space and the time required for the backup process, SpiderOak uses deduplication . This means that after the first upload of a file, only the individual changes need to be uploaded to the server and not the entire file each time. After the data backup process, the program can be used to synchronize with other computers and release files.
Additional services are offered for business customers.
Storage prices
The offer can be tested with 250 gigabytes of free storage space, whereby the test phase is limited to 21 days. You can choose between four options for a fee. There are 150 gigabytes, 400 gigabytes, 2 terabytes or 5 terabytes to choose from.
safety
To ensure user privacy, all data is stored locally, i. H. before upload, encrypted. According to the developers, the password is not available in clear text on the servers , unless the mobile apps or web access are used. In this case, the password is stored in the temporary memory of the SpiderOak server in order to decrypt the data on the server. This ensures that neither company employees nor strangers can access the data via the server. This is the so-called no-knowledge approach that the company is pursuing. One disadvantage that has to be taken into account is that there is no way to have a forgotten password sent to you. However, a password hint is set during registration, which helps to remember the password.
Since SpiderOak is based in the USA , it is subject to local law. This provides National Security Letters , which US authorities allow access to user data - also by requiring changes to a previously access-secure program (see Lavabit case ). Due to the confidentiality obligation that is regularly associated with a National Security Letter, it is generally not possible for the user to check the security of his data.
The client-side encryption and the zero-knowledge approach are the reasons why NSA whistleblower Edward Snowden recommended SpiderOak. In February 2017, however, the manufacturer pointed out that the description of the service as "Zero Knowledge" was technically incorrect and changed the name of its feature to "No Knowledge".
