Polarbackup is a new service from Zoolz, one of the best cloud storage providers on the market. They decided to establish an ultra-affordable service that offers unbeatable prices without sacrificing reliability and security, with an 89% reduction in their Cyber Monday sales. At €83.33 / €99.99 for a lifetime license for the 5TB tier, this is cheaper than buying an equivalent capacity hard drive. But wait, for a limited time only, they give you a free account when you buy one. So you end up with 10TB instead of 5TB. Your data is never deleted (because it will never expire); you can back up an unlimited number of external devices, from USB sticks to CCTV systems, and Polarbackup even supports file versioning. Polarbackup is compatible with Windows and Mac and does not use 256-bit encryption to protect your files. These are automatically backed up to Amazon's Glacier, one of the cheapest storage solutions on the market. Just keep in mind that Glacier is a cold store, which means you won't be able to get your files back right away. As Polarbackup explains, you may have to wait up to 12 hours to get your files back, which can be a major problem for some.
