Data corruption is the unintentional change of a file or the loss of info that usually occurs during reading or writing. The reason could be hardware or software fail, and as a consequence, a file may become partially or completely corrupted, so it'll no longer function as it should because its bits will be scrambled or missing. An image file, for example, will no longer show an accurate image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. In case such a problem occurs and it is not recognized by the system or by an admin, the data will be corrupted silently and when this happens on a disk drive that's part of a RAID array where the info is synchronized between various drives, the corrupted file shall be reproduced on all the other drives and the harm will become long term. A large number of widely used file systems either don't offer real-time checks or do not have good ones that can detect an issue before the damage is done, so silent data corruption is a very common issue on internet hosting servers where huge volumes of information are kept.
No Data Corruption & Data Integrity in Shared Website Hosting
The integrity of the data which you upload to your new shared website hosting
account will be guaranteed by the ZFS file system which we make use of on our cloud platform. The vast majority of internet hosting providers, like our company, use multiple hard drives to keep content and considering that the drives work in a RAID, the same info is synchronized between the drives all the time. If a file on a drive gets corrupted for whatever reason, yet, it is very likely that it will be reproduced on the other drives since alternative file systems don't feature special checks for this. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for each file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, which means that the damaged copy will be replaced with a good one from a different hard drive. As this happens immediately, there is no risk for any of your files to ever get corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be shielded from silent data corruption because all of our storage servers employ the reliable ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, to ensure the integrity of every single file. When you upload content to your account, it will be saved on a couple of redundant drives operating in a RAID i.e. the files shall be the same on all drives. All the copies of a particular file will feature the same checksum on all hard disks and ZFS will compare the checksums of the copies in real time, and if it finds a mismatch, that will indicate that one of the copies is corrupted, it will swap that file with a healthy copy from one of the other disks. Even if there is an unexpected power loss, the data on the servers won't get corrupted and there won't be any need for a time-consuming system check which other file systems perform following some malfunction, lengthening the time needed for the server to return online. ZFS is the sole file system that can truly protect your content from silent data corruption.
