Data corruption is the accidental transformation of a file or the losing of info that often occurs during reading or writing. The reason could be hardware or software failure, and as a consequence, a file could become partially or fully corrupted, so it will no longer function as it should since its bits will be scrambled or missing. An image file, for instance, will no longer show an authentic image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. In the event that such an issue appears and it isn't found by the system or by an administrator, the data will be corrupted silently and if this happens on a disk drive that's part of a RAID array where the data is synchronized between various drives, the corrupted file will be duplicated on all the other drives and the harm will be permanent. A number of commonly used file systems either do not have real-time checks or don't have good ones which will detect a problem before the damage is done, so silent data corruption is a rather common issue on hosting servers where substantial amounts of info 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 take advantage of on our cloud platform. Most of the web hosting suppliers, including our company, use multiple hard disks to keep content and since the drives work in a RAID, exactly the same data is synchronized between the drives all the time. In case a file on a drive is corrupted for some reason, however, it is more than likely that it will be reproduced on the other drives since alternative file systems don't have special checks for this. Unlike them, ZFS applies a digital fingerprint, or a checksum, for every single file. If a file gets damaged, its checksum won't match what ZFS has as a record for it, therefore the damaged copy will be substituted with a good one from a different hard disk drive. As this happens instantly, there's no risk for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't have to deal with any silent data corruption issues whatsoever if you purchase one of our semi-dedicated server solutions because the ZFS file system that we employ on our cloud hosting platform uses checksums in order to guarantee that all the files are undamaged at all times. A checksum is a unique digital fingerprint which is assigned to each and every file kept on a server. Because we store all content on a number of drives simultaneously, the same file has the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. In case 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 possibility of the corrupted copy to be synchronized on the rest of the hard disks. ZFS is the sole file system out there which uses checksums, which makes it much more reliable than other file systems which are not able to detect silent data corruption and copy bad files across drives.
