Data corruption is the unintended transformation of a file or the loss of information that usually occurs during reading or writing. The reason may be hardware or software malfunction, and as a result, a file could become partially or entirely corrupted, so it'll no longer work correctly as its bits shall be scrambled or missing. An image file, for instance, will no longer display an accurate image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. When this kind of an issue appears and it's not identified by the system or by an administrator, the data will become corrupted silently and when this happens on a drive which is part of a RAID array where the info is synced between various drives, the corrupted file shall be duplicated on all other drives and the harm will be long term. Numerous commonly used file systems either don't feature real-time checks or don't have good ones that can detect an issue before the damage is done, so silent data corruption is a common issue on hosting servers where huge volumes of information are kept.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You won't experience any kind of silent data corruption issues if you obtain one of our semi-dedicated hosting packages since the ZFS file system that we use on our cloud hosting platform uses checksums to guarantee that all of your files are undamaged all of the time. A checksum is a unique digital fingerprint which is assigned to each and every file kept on a server. Due to the fact that we store all content on a number of drives simultaneously, the same file uses the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives in real time. If it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy without delay, avoiding any probability of the damaged copy to be synchronized on the remaining drives. ZFS is the only file system you can get which uses checksums, which makes it far superior to other file systems that are not able to detect silent data corruption and duplicate bad files across drives.
