Data corruption is the unintended modification of a file or the losing of information which usually occurs during reading or writing. The reason may be hardware or software fail, and consequently, a file may become partially or completely corrupted, so it will no longer function correctly as its bits will be scrambled or missing. An image file, for instance, will no longer show an authentic image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. When this kind of an issue appears and it isn't found by the system or by an admin, the data will get corrupted silently and if this happens on a disk drive that is a part of a RAID array where the info is synced between different drives, the corrupted file shall be duplicated on all the other drives and the harm will be permanent. Numerous frequently used file systems either do not feature real-time checks or don't have high quality ones that can detect a problem before the damage is done, so silent data corruption is a rather common issue on internet hosting servers where substantial volumes of information are kept.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data that you upload to your new shared hosting account will be guaranteed by the ZFS file system that we make use of on our cloud platform. Most web hosting providers, like our company, use multiple HDDs to keep content and since the drives work in a RAID, identical information is synchronized between the drives all of the time. In case a file on a drive is corrupted for reasons unknown, yet, it is likely that it will be copied on the other drives since other file systems do not feature special checks for that. Unlike them, ZFS applies a digital fingerprint, or a checksum, for every single file. If a file gets corrupted, its checksum won't match what ZFS has as a record for it, therefore the bad copy shall be swapped with a good one from another hard disk drive. As this happens right away, there is no possibility for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server account will be resistant to silent data corruption since all of our storage servers make use of the state-of-the-art ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to verify the integrity of each and every file. When you upload content to your account, it'll be saved on several redundant drives being employed in a RAID i.e. the files will be the same across all 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 duplicates right away, so if it finds a mismatch, that would indicate that one of the copies is corrupted, it will swap that file with a healthy copy from one of the other disks. Even if there is a sudden power failure, the data on the servers will not be corrupted and there will not be any need for a time-consuming system check that other file systems perform after some breakdown, extending the time needed for the server to return online. ZFS is the sole file system which can really protect your content from silent data corruption.
