Data corruption is the accidental change of a file or the losing of info that usually occurs during reading or writing. The reason may be hardware or software fail, and consequently, a file could become partially or entirely corrupted, so it will no longer function correctly since its bits will be scrambled or missing. An image file, for example, will no longer display an authentic image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. When such an issue occurs and it isn't noticed by the system or by an admin, the data will get corrupted silently and if this happens on a disk drive that's part of a RAID array where the info is synced between various drives, the corrupted file shall be replicated on all the other drives and the damage will be permanent. A large number of widespread file systems either don't feature real-time checks or do not have good ones which will detect a problem before the damage is done, so silent data corruption is a very common matter on hosting servers where substantial amounts of data are kept.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data which you upload to your new shared hosting
account shall be guaranteed by the ZFS file system which we work with on our cloud platform. The majority of internet hosting suppliers, including our firm, use multiple hard disks to keep content and considering that the drives work in a RAID, the exact same data is synchronized between the drives at all times. In case a file on a drive is corrupted for some reason, however, it is more than likely that it will be duplicated on the other drives since alternative file systems do not include special checks for this. Unlike them, ZFS employs a digital fingerprint, or a checksum, for each and every file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, and the damaged copy will be replaced with a good one from a different hard disk drive. Because this happens instantly, there is no risk for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We've avoided any chance of files getting corrupted silently since the servers where your semi-dedicated hosting
account will be created use a powerful file system known as ZFS. Its advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. As we keep all content on numerous SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has saved. If there is a mismatch, the bad copy is replaced with a healthy one from one of the other drives and since it happens in real time, there is no chance that a corrupted copy could remain on our website hosting servers or that it can be copied to the other drives in the RAID. None of the other file systems use this kind of checks and what is more, even during a file system check right after a sudden power loss, none of them will detect silently corrupted files. In contrast, ZFS does not crash after an electrical power failure and the continual checksum monitoring makes a lenghty file system check unneeded.
