Data corruption is the unintentional transformation of a file or the loss of info which often occurs during reading or writing. The reason can be hardware or software malfunction, and due to this fact, a file can become partially or entirely corrupted, so it will no longer work correctly since its bits will be scrambled or lacking. An image file, for example, will no longer show a true image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. If such a problem appears and it's not noticed by the system or by an administrator, the data will get corrupted silently and if this happens on a drive that's part of a RAID array where the information is synchronized between various different drives, the corrupted file shall be reproduced on all of the other drives and the harm will become permanent. A number of commonly used file systems either don't have real-time checks or don't have good ones which will detect an issue before the damage is done, so silent data corruption is a rather common issue on web hosting servers where substantial amounts of info are stored.

No Data Corruption & Data Integrity in Shared Website Hosting

If you host your sites in a shared website hosting account from our firm, you won't have to worry about your data ever getting damaged. We can guarantee that as our cloud hosting platform works with the state-of-the-art ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each and every file. Any kind of data that you upload will be saved in a RAID i.e. simultaneously on many SSD drives. All of the file systems synchronize the files between the different drives with such a setup, but there's no real warranty that a file will not be corrupted. This may happen at the time of the writing process on any drive and after that a bad copy can be copied on the other drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all drives live and when a corrupted file is located, it is replaced with a good copy with the correct checksum from another drive. This way, your information will continue to be intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't need to deal with any kind of silent data corruption issues should you purchase one of our semi-dedicated server plans because the ZFS file system that we employ on our cloud hosting platform uses checksums in order to make sure that all of the files are undamaged all the time. A checksum is a unique digital fingerprint which is given to each and every file kept on a server. Because we store all content on a number of drives simultaneously, the same file uses the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives in real time. If it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy without delay, avoiding any chance of the corrupted copy to be synchronized on the other hard drives. ZFS is the only file system you can get that uses checksums, which makes it far superior to other file systems that cannot detect silent data corruption and duplicate bad files across hard drives.
