Data corruption is the unintended transformation of a file or the loss of information which usually occurs during reading or writing. The reason may be hardware or software failure, and for that reason, a file could become partially or completely corrupted, so it'll no longer work properly since its bits shall be scrambled or lost. An image file, for instance, will no longer present an actual image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. When this kind of an issue occurs and it is not noticed by the system or by an admin, the data will get corrupted silently and when this happens on a disk drive that is part of a RAID array where the info is synchronized between different drives, the corrupted file will be copied on all of the other drives and the harm will be long term. Numerous widespread file systems either do not 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 very common issue on internet hosting servers where huge amounts of information are stored.

No Data Corruption & Data Integrity in Web Hosting

We guarantee the integrity of the data uploaded in every web hosting account which is generated on our cloud platform as we work with the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption through a unique checksum for every single file. We'll store your information on multiple SSD drives that function in a RAID, so the same files will be available on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all drives in real time and in the event that the checksum of any file differs from what it needs to be, the file system swaps that file with a healthy version from some other drive inside the RAID. There's no other file system that uses checksums, so it is possible for data to become silently damaged and the bad file to be reproduced on all drives over time, but since this can never happen on a server running ZFS, you don't have to concern yourself with the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption as all of our storage servers work with the efficient ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to verify the integrity of every single file. When you upload content to your account, it'll be kept on several redundant drives working in a RAID i.e. the files shall be the same across all drives. All of the copies of a given file will feature the same checksum on all hard disks and ZFS will compare the checksums of the duplicates in real time, so if it registers a mismatch, that would indicate that one of the copies is damaged, it will substitute that file with a good copy from one of the other drives. Even if there's an unforeseen power loss, the data on the servers won't be corrupted and there won't be any need for a time-consuming system check that other file systems perform following some failure, prolonging the time needed for the server to get back online. ZFS is the file system which can really protect your content from silent data corruption.
