Data corruption is the accidental change of a file or the loss of information that often occurs during reading or writing. The reason can be hardware or software failure, and because of this, a file may become partially or fully corrupted, so it will no longer function as it should because its bits shall be scrambled or missing. An image file, for example, will no longer display an authentic image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. If this kind of an issue appears and it's not recognized by the system or by an administrator, the data will become corrupted silently and when this happens on a drive that is part of a RAID array where the information is synchronized between various different drives, the corrupted file will be replicated on all other drives and the damage will be long term. A number of frequently used file systems either do not have real-time checks or do not have high quality ones that will detect an issue before the damage is done, so silent data corruption is a rather common problem on hosting servers where huge amounts of data are kept.

No Data Corruption & Data Integrity in Cloud Web Hosting

We've tackled the matter of silent data corruption on all our cloud web hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is more advanced than other file systems because it is the only one out there which checks all the files immediately by using a checksum - a digital identifier that's unique for every single file. When you upload content to your account, it will be stored on several SSD drives and regularly synchronized between them for redundancy. ZFS regularly analyzes the checksum of all files and in case any file is detected as damaged, it is replaced quickly 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 rest of the SSDs. ZFS requires a lot of physical memory in order to execute the real-time checks and the advantage of our cloud website hosting platform is that we work with multiple powerful servers working together. If you host your websites with us, your information will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption as all our storage servers use the efficient ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, in order to ensure the integrity of each and every file. When you upload content to your account, it will be placed on several redundant drives operating in a RAID i.e. the files shall be the same on all drives. All copies of a given file will feature the same checksum on all drives and ZFS will compare the checksums of the duplicates in real time, so if it discovers a mismatch, which will indicate that one of the copies is corrupted, it will substitute that file with a healthy copy from one of the other drives. Even if there is a sudden power loss, the data on the servers won't become corrupted and there will not 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 go back online. ZFS is the only file system that can really protect your content from silent data corruption.
