Data corruption is the accidental modification of a file or the losing of info which often occurs during reading or writing. The reason may be hardware or software failure, and for that reason, a file could become partially or completely corrupted, so it'll no longer work correctly as its bits shall be scrambled or missing. An image file, for instance, will no longer present an accurate image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. When this kind of a problem occurs and it is not recognized by the system or by an administrator, the data will become corrupted silently and if this happens on a drive which is part of a RAID array where the data is synced between various different drives, the corrupted file shall be reproduced on all other drives and the damage will be permanent. Many commonly used file systems either don't feature real-time checks or do not have high quality ones which can detect an issue before the damage is done, so silent data corruption is a very common problem on 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 ensured by the ZFS file system that we work with on our cloud platform. The majority of hosting service providers, like our company, use multiple hard disk drives to store content and since the drives work in a RAID, the same information is synchronized between the drives all of the time. If a file on a drive becomes corrupted for reasons unknown, however, it's more than likely that it will be reproduced on the other drives as other file systems don't offer special checks for this. Unlike them, ZFS employs a digital fingerprint, or a checksum, for every single file. If a file gets damaged, its checksum will not match what ZFS has as a record for it, and the bad copy shall be replaced with a good one from a different hard drive. As this happens in real time, there's 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 protected against silent data corruption as all our storage servers work with the advanced ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, to guarantee the integrity of each and every file. When you upload content to your account, it'll be saved on several redundant drives operating in a RAID i.e. the files shall be the same on all drives. All the copies of a specific file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies quickly, and if it identifies a mismatch, which will indicate that one of the copies is corrupted, it will replace that file with a good 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 won't be any need for a time-consuming system check which other file systems perform following some malfunction, extending the time needed for the server to go back online. ZFS is the only file system that can truly protect your content from silent data corruption.
