Data corruption is the unintended transformation of a file or the losing of info which usually occurs during reading or writing. The reason may be hardware or software malfunction, and as a result, a file may become partially or fully corrupted, so it'll no longer function as it should because its bits will be scrambled or missing. 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 since its content will be unreadable, and so on. In case such a problem appears and it is not recognized by the system or by an administrator, the data will be corrupted silently and in case this happens on a disk drive which is a part of a RAID array where the information is synced between various different drives, the corrupted file shall be reproduced on all the other drives and the damage will become permanent. Numerous widely used file systems either don't offer real-time checks or don't have good ones which will detect an issue before the damage is done, so silent data corruption is a rather common problem on web hosting servers where large amounts of information are stored.

No Data Corruption & Data Integrity in Shared Web Hosting

We warrant the integrity of the information uploaded in each and every shared web hosting account which is created on our cloud platform since we employ the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption through a unique checksum for every single file. We shall store your information on multiple SSD drives which work in a RAID, so the very same files will be present on several places at the same time. ZFS checks the digital fingerprint of all files on all the drives in real time and in case the checksum of any file is different from what it should be, the file system replaces that file with an undamaged version from a different drive within the RAID. There's no other file system which uses checksums, so it is easy for data to get silently damaged and the bad file to be replicated on all drives over time, but since that can never happen on a server using ZFS, you don't have to concern yourself with the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not have to deal with any silent data corruption issues whatsoever in case you acquire one of our semi-dedicated server plans due to the fact that the ZFS file system that we employ on our cloud hosting platform uses checksums to ensure that all of your files are intact all of the time. A checksum is a unique digital fingerprint that is assigned to each and every file stored on a server. As we store all content on multiple drives simultaneously, the same file uses the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. In the event that it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy without delay, avoiding any probability of the bad copy to be synchronized on the other drives. ZFS is the sole file system you can get which uses checksums, which makes it much more reliable than other file systems that are not able to identify silent data corruption and copy bad files across drives.
