Data corruption is the unintended transformation of a file or the losing of information that usually occurs during reading or writing. The reason may be hardware or software fail, and as a result, a file could become partially or entirely corrupted, so it will no longer function correctly because its bits will be scrambled or lacking. An image file, for example, will no longer show a real image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etc. In the event that such an issue occurs and it is not found by the system or by an administrator, the data will become corrupted silently and when this happens on a disk drive that is part of a RAID array where the info is synced between various different drives, the corrupted file will be copied on all of the other drives and the harm will be long term. Many popular file systems either do not offer real-time checks or do not have high quality ones which can detect a problem before the damage is done, so silent data corruption is a very common matter on web hosting servers where substantial volumes of data are kept.
No Data Corruption & Data Integrity in Shared Web Hosting
The integrity of the data that you upload to your new shared web hosting account will be guaranteed by the ZFS file system that we work with on our cloud platform. Most internet hosting suppliers, including our firm, use multiple hard disks to store content and since the drives work in a RAID, exactly the same info is synchronized between the drives all the time. When a file on a drive is corrupted for reasons unknown, yet, it is more than likely that it will be reproduced on the other drives since other file systems don't offer special checks for this. Unlike them, ZFS applies a digital fingerprint, or a checksum, for each and every file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, which means that the damaged copy will be substituted with a good one from a different drive. Because this happens immediately, there is no possibility for any of your files to ever get corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server account will be resistant to silent data corruption because all our storage servers use the reliable ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order to ensure the integrity of each file. When you upload content to your account, it'll be saved on several redundant drives employed in a RAID i.e. the files shall be the same on all disk drives. All of the copies of a given file will have the same checksum on all drives and ZFS will compare the checksums of the copies in real time, so if it detects a mismatch, that will indicate that one of the copies is corrupted, it will replace that file with a healthy copy from one of the other disks. Even if there is an unforeseen power failure, the data on the servers won't become corrupted and there won't be any need for a time-consuming system check which other file systems perform after some breakdown, lengthening the time needed for the server to get back online. ZFS is the file system that can really protect your content from silent data corruption.
