The process of files getting damaged caused by some hardware or software failure is referred to as data corruption and this is among the main problems which web hosting companies face since the larger a hard disk is and the more info is placed on it, the more likely it is for data to get corrupted. There are several fail-safes, still often the info is damaged silently, so neither the particular file system, nor the administrators notice a thing. Thus, a damaged file will be handled as a good one and if the hard disk drive is a part of a RAID, the file will be copied on all other disk drives. In principle, this is done for redundancy, but in reality the damage will be worse. The moment a file gets damaged, it will be partly or completely unreadable, which means that a text file will not be readable, an image file will display a random mix of colors if it opens at all and an archive shall be impossible to unpack, so you risk sacrificing your content. Although the most popular server file systems have various checks, they often fail to discover a problem early enough or require a vast amount of time to be able to check all files and the web hosting server will not be functional for the time being.

No Data Corruption & Data Integrity in Shared Web Hosting

If you host your sites in a shared web hosting account from our company, you do not have to worry about any of your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform uses the amazing ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for every single file. Any kind of information that you upload will be saved in a RAID i.e. simultaneously on many SSD drives. Many file systems synchronize the files between the separate drives with this type of a setup, but there is no real guarantee that a file will not get corrupted. This could occur throughout the writing process on any drive and after that a damaged copy can be copied on the rest of the drives. What is different on our platform is that ZFS examines the checksums of all files on all the drives live and if a corrupted file is found, it's substituted with a good copy with the correct checksum from some other drive. That way, your data will stay intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you go for one of our semi-dedicated hosting packages, you won't have to worry about silent data corruption as we use ZFS - an advanced file system that keeps track of all of the files in real time. Every time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between a number of SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from a different drive. This happens immediately, so there will be no risk for any part of your content at any moment. In contrast, all the other file systems perform checks after a system malfunction, but since they don't use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a bad copy could be replicated on the rest of the drives as well and you may lose precious information. Since this is not the case with ZFS, we can guarantee the integrity of every single file you upload no matter what.
