Data corruption is the unintended modification of a file or the losing of information which usually occurs during reading or writing. The reason may be hardware or software failure, and consequently, a file could become partially or fully corrupted, so it will no longer function as it should because its bits will be scrambled or lost. An image file, for example, will no longer display a true image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. If this kind of a problem occurs and it isn't noticed by the system or by an admin, the data will be corrupted silently and when this happens on a drive that is part of a RAID array where the data is synced between various different drives, the corrupted file shall be reproduced on all the other drives and the damage will become long term. Many commonly used file systems either do not feature 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 common problem on hosting servers where huge amounts of information are stored.

No Data Corruption & Data Integrity in Website Hosting

We have resolved the matter of silent data corruption on all of our website hosting servers by using the modern Z file system, or ZFS. The latter is better than other file systems as it is the only one in existence which checks all the files in real time by using a checksum - a digital identifier that's unique for each file. When you upload content to your account, it will be stored on several NVMe drives and regularly synchronized between them for redundancy. ZFS regularly examines the checksum of all files and when any file is detected as corrupted, it's replaced quickly with a good copy from some other disk. As this happens in real time, there's no risk that a damaged file may remain or may be copied on the remaining NVMes. ZFS needs a lot of physical memory in order to perform the real-time checks and the benefit of our cloud hosting platform is that we use multiple very powerful servers working together. In case you host your Internet sites with us, your data 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 because all of our storage servers work with the advanced ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order to verify the integrity of every single file. When you upload content to your account, it'll be stored on a couple of redundant drives being employed in a RAID i.e. the files shall be the same across all disk drives. All copies of a specific file will feature the same checksum on all drives and ZFS will compare the checksums of the copies in real time, so if it finds a mismatch, which would indicate that one of the copies is corrupted, it'll substitute that file with a good copy from one of the other disks. Even if there is an unforeseen power failure, the data on the servers will not be corrupted and there won't be any need for a time-consuming system check that other file systems perform after some malfunction, prolonging the time needed for the server to get back online. ZFS is the sole file system that can really protect your content from silent data corruption.
