Data corruption is the unintentional transformation of a file or the loss of info that usually occurs during reading or writing. The reason may be hardware or software fail, and as a result, a file can become partially or completely corrupted, so it'll no longer function as it should because its bits will be scrambled or lost. An image file, for instance, will no longer display an actual image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. If such an issue appears and it isn't recognized by the system or by an administrator, the data will be corrupted silently and if this happens on a disk drive that's a part of a RAID array where the information is synchronized between various different drives, the corrupted file will be duplicated on all of the other drives and the harm will become permanent. Many widely used file systems either do not offer 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 very common problem on hosting servers where huge volumes of info are stored.
No Data Corruption & Data Integrity in Cloud Hosting
The integrity of the data that you upload to your new cloud hosting account will be ensured by the ZFS file system that we use on our cloud platform. The majority of web hosting suppliers, like our company, use multiple hard disks to keep content and considering that the drives work in a RAID, exactly the same info is synchronized between the drives at all times. If a file on a drive gets damaged for some reason, however, it is more than likely that it will be reproduced on the other drives as other file systems do not include special checks for that. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for each and every file. If a file gets corrupted, its checksum won't match what ZFS has as a record for it, and the damaged copy will be substituted with a good one from another hard disk drive. Since this happens instantly, there is no possibility for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any possibility of files getting corrupted silently because the servers where your semi-dedicated server account will be created use a powerful file system called ZFS. Its key advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint which is checked in real time. Since we keep all content on a number of SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. In the event that there's a mismatch, the bad copy is replaced with a healthy one from one of the other drives and since it happens instantly, there's no chance that a corrupted copy could remain on our website hosting servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems include this kind of checks and in addition, even during a file system check after a sudden power loss, none of them will detect silently corrupted files. In comparison, ZFS doesn't crash after an electrical power failure and the continual checksum monitoring makes a lenghty file system check unnecessary.
