How do you protect your files, photos, and documents from hard drive failure, theft, and malware like ransomware?
The most well-known way to backup data is to copy it to an external hard drive. But your external hard drive is not immune to physical mishaps, and it will fail eventually.
Offsite backup is a solution that allows your files to be replicated somewhere out of your home. But with cloud backup comes the risks to privacy and security: Dropbox was hacked, and they store files without any at-rest encryption, which means anyone with physical access can read your data.
Of course, you can encrypt your data before sending it to the cloud. But this may be a complicated and time-consuming process. And then you have to manage encryption keys. You shouldn't have to trade convenience for security.
SpiderOak is different. Indeed, SpiderOakOne is built upon zero-knowledge. They know nothing about the encrypted data stored on their servers.
SpiderOak is running an exceptional offer:
unlimited encrypted backup for $149 per year. no longer available, see top of the page
Until February 1st, you can subscribe to this offer and get unlimited storage in an unlimited number of devices (unlike competitors like CrashPlan that limit the number of devices).
The price stays fixed for as long as you stay subscribed.
SpiderOak One is available on Windows, Mac OS, Linux (Fedora, Debian Slackware) and includes useful features such as unlimited file versioning, real-time sync between devices, and access from Android and iOS devices.
Now for the technical bits, your SpiderOak password will be hashed with multi-round and salted PBKDF2 (SHA-256 with more than 16000 rounds, and a 32 byte Salt of random data).
Be prepared, back up everything, encrypted.
