Data corruption is the accidental change of a file or the loss of information which often occurs during reading or writing. The reason may be hardware or software failure, and as a result, a file can become partially or completely corrupted, so it will no longer work as it should as its bits will be scrambled or missing. An image file, for example, will no longer present an authentic image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. In case this kind of a problem appears and it's not identified by the system or by an admin, the data will be corrupted silently and if this happens on a drive which is a part of a RAID array where the data is synchronized between various different drives, the corrupted file will be copied on all other drives and the harm will become permanent. A number of widely used file systems either don't feature real-time checks or do not have good ones which can detect an issue before the damage is done, so silent data corruption is a common issue on internet hosting servers where large volumes of information are kept.

No Data Corruption & Data Integrity in Cloud Web Hosting

We warrant the integrity of the information uploaded in each and every cloud web hosting account which is created on our cloud platform due to the fact that we work with the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption using a unique checksum for every single file. We will store your data on a large number of SSD drives which work in a RAID, so the very same files will be available on several places at once. ZFS checks the digital fingerprint of all of the files on all of the drives in real time and in case the checksum of any file differs from what it needs to be, the file system replaces that file with an undamaged copy from another drive from the RAID. There's no other file system which uses checksums, so it is possible for data to get silently damaged and the bad file to be replicated on all drives over time, but since this can never happen on a server using ZFS, you don't have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption as 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, to guarantee the integrity of each and every file. When you upload content to your account, it will be kept on several redundant drives working in a RAID i.e. the files will be the same across all disks. All of the copies of a particular file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates in real time, and if it identifies a mismatch, which will indicate that one of the copies is corrupted, it'll replace 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 malfunction, extending the time needed for the server to return online. ZFS is the file system which can truly protect your content from silent data corruption.
