Data corruption is the unintended modification of a file or the loss of information that often occurs during reading or writing. The reason can be hardware or software fail, and because of this, a file could become partially or completely corrupted, so it'll no longer function as it should because its bits will be scrambled or lost. An image file, for instance, will no longer present a real image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. In case such an issue appears and it isn't recognized by the system or by an administrator, the data will get corrupted silently and if this happens on a disk drive which is a part of a RAID array where the information is synchronized between various different drives, the corrupted file shall be replicated on all the other drives and the harm will be long term. A large number of commonly used file systems either don't feature real-time checks or don't have good ones that can detect an issue before the damage is done, so silent data corruption is a rather common matter on hosting servers where huge amounts of info are stored.

No Data Corruption & Data Integrity in Shared Web Hosting

We have resolved the problem of silent data corruption on all of our shared web hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is superior to other file systems because it is the only one in existence that checks all the files instantly by using a checksum - a digital identifier that's unique for each file. When you upload content to your account, it will be stored on several SSD drives and constantly synced between them for redundancy. ZFS constantly analyzes the checksum of all files and in the event that any file is detected as damaged, it's replaced instantly with a good copy from some other disk. As this happens in real time, there's no risk that a corrupted file may remain or may be copied on the remaining SSDs. ZFS needs a lot of physical memory to execute the real-time checks and the advantage of our cloud website hosting platform is that we employ multiple powerful servers working together. If you host your sites with us, your information will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not experience any silent data corruption issues if you obtain one of our semi-dedicated server packages because the ZFS file system that we use on our cloud hosting platform uses checksums in order to guarantee that all the files are undamaged all the time. A checksum is a unique digital fingerprint that is given to each and every file kept on a server. As we store all content on multiple drives at the same time, the same file has the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. When 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 possibility of the bad copy to be synchronized on the other hard disks. ZFS is the sole file system out there which uses checksums, which makes it much more dependable than other file systems that are not able to identify silent data corruption and duplicate bad files across drives.
