Data corruption is the unintentional transformation of a file or the losing of info which often occurs during reading or writing. The reason can be hardware or software failure, and as a consequence, a file may become partially or completely corrupted, so it'll no longer work properly since its bits shall be scrambled or missing. An image file, for example, will no longer present a real image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etc. In the event that this kind of an issue occurs and it is not identified by the system or by an admin, the data will become corrupted silently and when this happens on a disk drive that's part of a RAID array where the data is synchronized between various different drives, the corrupted file shall be replicated on all the other drives and the harm will be long term. A number of widely used file systems either don't have real-time checks or don't have good ones that will detect an issue before the damage is done, so silent data corruption is a rather common matter on internet hosting servers where large amounts of data are stored.
No Data Corruption & Data Integrity in Website Hosting
We guarantee the integrity of the data uploaded in every website 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 prevent silent data corruption via a unique checksum for each file. We will store your information on a large number of SSD drives that function in a RAID, so the very same files will exist on several places simultaneously. ZFS checks the digital fingerprint of all the files on all of the drives in real time and if the checksum of any file is different from what it should be, the file system replaces that file with a healthy copy from another drive from the RAID. There's no other file system that uses checksums, so it's possible for data to be silently damaged and the bad file to be duplicated on all drives with time, but since this can never happen on a server running ZFS, you won't have to concern yourself with the integrity of your data.
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 work with the innovative ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, so as to guarantee the integrity of every single file. When you upload content to your account, it will be placed on several redundant drives working in a RAID i.e. the files will be the same on all disks. All copies of a specific file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates right away, so if it registers 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 disks. Even if there is an unexpected blackout, the data on the servers won't get corrupted and there will not be any need for a time-consuming system check that other file systems perform following some malfunction, lengthening the time needed for the server to return online. ZFS is the file system that can truly protect your content from silent data corruption.
