Data corruption is the unintended transformation of a file or the loss of information that often occurs during reading or writing. The reason can be hardware or software fail, and for that reason, a file can become partially or completely corrupted, so it'll no longer function properly because 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 as its content will be unreadable, etcetera. In case this kind of an issue occurs and it is not recognized by the system or by an admin, the data will become corrupted silently and in case this happens on a disk drive that's part of a RAID array where the data is synced between various drives, the corrupted file will be duplicated on all of the other drives and the harm will become permanent. Numerous commonly used file systems either do not have real-time checks or don't have good ones that will detect a problem before the damage is done, so silent data corruption is a very common issue on hosting servers where large volumes of information are stored.

No Data Corruption & Data Integrity in Hosting

We have tackled the matter of silent data corruption on all of our hosting servers by using the leading-edge Z file system, or ZFS. The latter is more advanced than other file systems since it is the only one in existence which checks all files immediately by employing a checksum - a digital identifier that is unique for each file. When you upload content to your account, it'll be stored on several SSD drives and continually 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 is replaced immediately with a good copy from another disk. As this happens in real time, there's no risk that a corrupted file may remain or may be duplicated on the other SSDs. ZFS requires lots of physical memory in order to carry out the real-time checks and the advantage of our cloud web hosting platform is that we work with multiple powerful servers working together. In case you host your sites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be protected against silent data corruption since all of our storage servers work with the innovative ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, so as to verify the integrity of each file. When you upload content to your account, it'll be kept on several redundant drives operating in a RAID i.e. the files shall be the same across all disk drives. All of the copies of a specific file will feature the same checksum on all hard drives and ZFS will compare the checksums of the duplicates quickly, so if it detects a mismatch, that would indicate that one of the copies is corrupted, it'll swap that file with a healthy copy from one of the other drives. Even if there is an unforeseen blackout, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check which other file systems perform following some breakdown, prolonging the time needed for the server to get back online. ZFS is the sole file system that can truly protect your content from silent data corruption.
