Data corruption is the unintentional change of a file or the losing of info which often occurs during reading or writing. The reason could be hardware or software malfunction, and for that reason, a file could become partially or fully corrupted, so it will no longer work properly as its bits shall be scrambled or lost. An image file, for instance, will no longer show a real image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. In the event that this kind of an issue appears and it isn't recognized by the system or by an admin, the data will get corrupted silently and if this happens on a drive that is part of a RAID array where the data is synced between different drives, the corrupted file shall be duplicated on all other drives and the harm will become long term. A large number of widely used file systems either do not offer real-time checks or don't have high quality ones which will detect an issue before the damage is done, so silent data corruption is a very common problem on web hosting servers where substantial volumes of information are kept.

No Data Corruption & Data Integrity in Website Hosting

We've dealt with the problem of silent data corruption on all of our website hosting servers by using the hi-tech Z file system, or ZFS. The latter is better than other file systems since it is the only one out there which checks all of the files instantly by using a checksum - a digital identifier which is unique for each and every file. When you upload content to your account, it will be stored on several NVMe drives and continually synchronized between them for redundancy. ZFS constantly compares the checksum of all files and if any file is detected as damaged, it is replaced immediately with a good copy from another disk. As this happens in real time, there is no risk that a corrupted file may remain or may be copied on the other NVMes. 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 employ 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 Hosting

Your semi-dedicated hosting account will be shielded from silent data corruption as all of our storage servers employ the advanced ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, so as to guarantee the integrity of each and every file. When you upload content to your account, it'll be saved on several redundant drives in a RAID i.e. the files shall be the same on all disks. All copies of a given file will feature the same checksum on all drives and ZFS will compare the checksums of the copies in real time, so if it detects a mismatch, that will indicate that one of the copies is corrupted, it will replace that file with a healthy copy from one of the other drives. Even if there is an unexpected power failure, 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 breakdown, extending the time needed for the server to get back online. ZFS is the file system which can truly protect your content from silent data corruption.
