Data corruption is the unintended change of a file or the losing of info which often occurs during reading or writing. The reason could be hardware or software fail, and for that reason, a file could become partially or completely corrupted, so it'll no longer work as it should since its bits shall be scrambled or lost. An image file, for instance, will no longer display a true image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etc. In the event that such a problem appears and it isn't recognized by the system or by an admin, the data will become corrupted silently and if this happens on a disk drive which is part of a RAID array where the info is synchronized between various drives, the corrupted file shall be copied on all the other drives and the harm will become permanent. Numerous popular file systems either don't feature real-time checks or do not have high quality ones which will detect a problem before the damage is done, so silent data corruption is a rather common problem on internet hosting servers where substantial amounts of information are stored.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data that you upload to your new shared hosting account shall be ensured by the ZFS file system that we work with on our cloud platform. The majority of web hosting service providers, including our company, use multiple hard drives to keep content and because the drives work in a RAID, exactly the same information is synchronized between the drives at all times. When a file on a drive is corrupted for some reason, however, it is likely that it will be reproduced on the other drives as other file systems do not offer special checks for this. Unlike them, ZFS employs a digital fingerprint, or a checksum, for every single file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, which means that the bad copy shall be replaced with a good one from another hard drive. Since this happens in real time, there is no risk for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You will not experience any kind of silent data corruption issues should you obtain one of our semi-dedicated server packages due to the fact that the ZFS file system that we employ on our cloud hosting platform uses checksums in order to make sure that all the files are intact all of the time. A checksum is a unique digital fingerprint which is given to each and every file kept on a server. Because we store all content on multiple drives at the same time, the same file has the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives in real time. In the event that 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 right away, avoiding any probability of the corrupted copy to be synchronized on the remaining drives. ZFS is the sole file system available on the market which uses checksums, which makes it far superior to other file systems which cannot detect silent data corruption and duplicate bad files across drives.
