Data corruption is the unintentional change of a file or the losing of info that usually occurs during reading or writing. The reason may be hardware or software fail, and because of this, a file could become partially or fully corrupted, so it will no longer function properly because its bits will be scrambled or lost. An image file, for instance, will no longer display an actual image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etc. In the event that this kind of a problem occurs and it's not found by the system or by an administrator, the data will be corrupted silently and in case this happens on a disk drive which is part of a RAID array where the data is synchronized between various different drives, the corrupted file will be copied on all the other drives and the damage will become long term. A large number of commonly used file systems either do not offer real-time checks or don't have high quality ones which can detect an issue before the damage is done, so silent data corruption is a common issue on web hosting servers where huge volumes of data are stored.

No Data Corruption & Data Integrity in Cloud Web Hosting

The integrity of the data which you upload to your new cloud web hosting account shall be ensured by the ZFS file system which we make use of on our cloud platform. Most hosting providers, including our company, use multiple hard disks to keep content and because the drives work in a RAID, exactly the same info is synchronized between the drives all of the time. If a file on a drive is corrupted for reasons unknown, however, it is more than likely that it will be reproduced on the other drives as other file systems do not have special checks for that. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for every single file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, which means that the damaged copy shall be swapped with a good one from a different hard disk. Since this happens in real time, there's no possibility for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be protected against silent data corruption since all of our storage servers use the efficient ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, in order to guarantee the integrity of every single file. When you upload content to your account, it will be kept on several redundant drives employed in a RAID i.e. the files will be the same on all drives. All of the copies of a specific file will feature the same checksum on all drives and ZFS will compare the checksums of the copies right away, so if it finds a mismatch, that will indicate that one of the copies is damaged, it will swap that file with a good copy from one of the other disks. Even if there is an unforeseen power loss, the data on the servers won't get corrupted and there will not be any need for a time-consuming system check that other file systems perform after some failure, prolonging the time needed for the server to go back online. ZFS is the sole file system that can truly protect your content from silent data corruption.
