Data corruption is the unintentional transformation of a file or the losing of information which usually occurs during reading or writing. The reason can be hardware or software failure, and due to this fact, a file may become partially or fully corrupted, so it'll no longer function properly as its bits shall be scrambled or missing. An image file, for example, will no longer show an actual image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etc. If such an issue appears and it isn't recognized by the system or by an admin, the data will get corrupted silently and when this happens on a disk drive that is a part of a RAID array where the info is synchronized between different drives, the corrupted file shall be copied on all other drives and the harm will be permanent. Numerous commonly used file systems either do not have real-time checks or do not have good ones that can detect a problem before the damage is done, so silent data corruption is a very common issue 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 ensured by the ZFS file system that we work with on our cloud platform. Most of the internet hosting suppliers, including our company, use multiple hard drives to store content and considering that the drives work in a RAID, identical info is synchronized between the drives all of the time. If a file on a drive is damaged for reasons unknown, however, it is likely that it will be copied on the other drives as other file systems do not have special checks for this. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for each file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, which means that the damaged copy shall be replaced with a good one from a different hard drive. As this happens in real time, 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 shielded from silent data corruption as all our storage servers use the innovative ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, in order to ensure the integrity of each file. When you upload content to your account, it'll be placed on a couple of redundant drives employed in a RAID i.e. the files shall be the same on all disks. All copies of a given file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates in real time, so if it discovers a mismatch, which will indicate that one of the copies is corrupted, it'll substitute that file with a healthy copy from one of the other disks. Even if there's a sudden blackout, the data on the servers won't get corrupted and there will not be any need for a time-consuming system check which other file systems perform after some breakdown, prolonging the time needed for the server to return online. ZFS is the sole file system that can really protect your content from silent data corruption.
