Data corruption is the unintended change of a file or the loss of info that often occurs during reading or writing. The reason may be hardware or software fail, and for that reason, a file can become partially or entirely corrupted, so it will no longer work as it should as its bits will be scrambled or lacking. An image file, for instance, will no longer display an actual image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. In case this kind of an issue occurs and it's not recognized by the system or by an administrator, 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 synchronized between different drives, the corrupted file shall be copied on all other drives and the damage will be long term. A number of widespread file systems either do not have real-time checks or don't have high quality ones that can detect an issue before the damage is done, so silent data corruption is a very common problem on internet hosting servers where substantial amounts of info are stored.

No Data Corruption & Data Integrity in Cloud Hosting

We've resolved the matter of silent data corruption on all of our cloud hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is better than other file systems since it is the only one in existence which checks all the files in real time by using a checksum - a digital identifier that is unique for each and every file. When you upload content to your account, it'll be stored on several NVMe drives and frequently synced between them for redundancy. ZFS regularly analyzes the checksum of all files and in the event that any file is detected as corrupted, it is replaced promptly with a good copy from another disk. As this happens in real time, there is no risk that a damaged file may remain or may be copied on the rest of the NVMes. ZFS needs lots of physical memory in order to perform the real-time checks and the benefit of our cloud website hosting platform is that we take advantage of multiple powerful servers working together. In case you host your Internet 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 as all our storage servers work with the reliable ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, so as to ensure the integrity of each file. When you upload content to your account, it'll be placed on several redundant drives operating in a RAID i.e. the files shall be the same across all disks. All the copies of a particular file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates right away, so if it finds a mismatch, that would 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's an unforeseen power loss, the data on the servers won't become corrupted and there will not 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 return online. ZFS is the sole file system that can really protect your content from silent data corruption.
