Data corruption is the unintended transformation of a file or the loss of information which often occurs during reading or writing. The reason may be hardware or software fail, and as a result, a file can become partially or completely corrupted, so it'll no longer function properly since its bits will be scrambled or lost. An image file, for example, will no longer display a real image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etc. When this kind of a problem occurs and it's not identified by the system or by an admin, the data will get corrupted silently and if this happens on a drive that's part of a RAID array where the info is synchronized between various drives, the corrupted file will be duplicated on all other drives and the damage will be long term. Many popular file systems either don't offer 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 common matter on internet hosting servers where substantial amounts of info are kept.

No Data Corruption & Data Integrity in Cloud Hosting

We've resolved the problem of silent data corruption on our cloud hosting servers by using the hi-tech Z file system, or ZFS. The latter is more advanced than other file systems because it is the only one on the market which checks all of the files in real time by employing a checksum - a digital identifier that is unique for each file. When you upload content to your account, it will be stored on several NVMe drives and continually synchronized 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 some other disk. As this happens in real time, there's no risk that a bad file may remain or may be duplicated on the other NVMes. ZFS needs plenty of physical memory to execute the real-time checks and the advantage of our cloud website hosting platform is that we work with multiple very powerful servers working together. In case you host your websites with us, your data will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be resistant to silent data corruption because all of our storage servers employ the effective ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to guarantee the integrity of each and every file. When you upload content to your account, it will be kept on several redundant drives employed in a RAID i.e. the files shall be the same across all drives. All the copies of a given file will feature the same checksum on all hard drives and ZFS will compare the checksums of the duplicates quickly, and if it finds a mismatch, which would indicate that one of the copies is corrupted, it will replace that file with a good copy from one of the other drives. Even if there's an unexpected power loss, the data on the servers will not become corrupted and there will not be any need for a time-consuming system check which other file systems perform following some failure, lengthening the time needed for the server to go back online. ZFS is the sole file system which can really protect your content from silent data corruption.
