The process of files being corrupted because of some hardware or software failure is called data corruption and this is one of the main problems which Internet hosting companies face because the larger a hard disk drive is and the more information is stored on it, the more likely it is for data to become corrupted. You can find various fail-safes, still often the data is corrupted silently, so neither the file system, nor the admins notice anything. Consequently, a damaged file will be handled as a regular one and if the hard disk is part of a RAID, the file will be copied on all other drives. Theoretically, this is done for redundancy, but in practice the damage will be even worse. When a given file gets corrupted, it will be partially or completely unreadable, therefore a text file will no longer be readable, an image file will show a random combination of colors if it opens at all and an archive shall be impossible to unpack, and you risk losing your content. Although the most frequently used server file systems feature various checks, they often fail to find a problem early enough or require a long time period in order to check all of the files and the web server will not be operational in the meantime.

No Data Corruption & Data Integrity in Cloud Web Hosting

In case you host your Internet sites in a cloud web hosting account from our company, you won't have to worry about your data ever getting corrupted. We can guarantee that since our cloud hosting platform employs the revolutionary ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each file. All info that you upload will be kept in a RAID i.e. simultaneously on a large number of SSD drives. All of the file systems synchronize the files between the separate drives using this kind of a setup, but there's no real warranty that a file won't be corrupted. This could happen during the writing process on any drive and after that a corrupted copy can be copied on the other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all of the drives live and in case a corrupted file is found, it's swapped with a good copy with the correct checksum from some other drive. In this way, your info will continue to be unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you get one of our semi-dedicated hosting packages, you won't need to worry about silent data corruption as we use ZFS - a high level file system which keeps track of all files in real time. Whenever you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between several SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all the copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done immediately, so there will be no risk for any part of your content at any time. In comparison, other file systems execute checks only after a system failure, but since they do not use anything similar to the checksums that ZFS uses, they cannot detect silently corrupted files, so a bad copy can be replicated on the rest of the drives as well and you may lose crucial data. As this is not the case with ZFS, we are able to warrant the integrity of each file you upload no matter what.
