Data corruption is the unintended modification of a file or the losing of information that usually occurs during reading or writing. The reason may be hardware or software failure, and due to this fact, a file may become partially or fully corrupted, so it'll no longer function as it should as its bits shall be scrambled or lacking. An image file, for example, will no longer show an actual image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. In the event that such an issue appears and it's not found by the system or by an admin, the data will become corrupted silently and when this happens on a drive that's a part of a RAID array where the info is synced between different drives, the corrupted file will be reproduced on all of the other drives and the damage will become permanent. Numerous commonly used file systems either do not offer real-time checks or don't have good ones which can detect an issue before the damage is done, so silent data corruption is a very common issue on web hosting servers where substantial amounts of data are kept.

No Data Corruption & Data Integrity in Web Hosting

We've resolved the matter of silent data corruption on all of our web hosting servers by using the cutting-edge Z file system, or ZFS. The latter is superior to other file systems since it is the only one out there which checks all of the files right away by employing a checksum - a digital identifier which is unique for every single file. When you upload content to your account, it'll be stored on several SSD drives and regularly synchronized between them for redundancy. ZFS constantly examines the checksum of all files and if any file is detected as corrupted, it is replaced instantly with a good copy from another disk. As this happens in real time, there is no risk that a bad file may remain or may be duplicated on the remaining SSDs. ZFS requires a lot of physical memory in order to carry out the real-time checks and the advantage of our cloud web hosting platform is that we use multiple very powerful servers working together. If you host your websites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be resistant to silent data corruption since all of our storage servers use the innovative ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to ensure the integrity of every single file. When you upload content to your account, it will be placed on a couple of redundant drives working in a RAID i.e. the files will be the same across all disk drives. All of the copies of a particular file will feature the same checksum on all drives and ZFS will compare the checksums of the copies right away, so if it identifies a mismatch, that will indicate that one of the copies is corrupted, it'll swap that file with a good copy from one of the other disks. Even if there is an unexpected blackout, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check that other file systems perform following some malfunction, extending the time needed for the server to get back online. ZFS is the only file system that can truly protect your content from silent data corruption.
