Data corruption is the damage of info because of various hardware or software fails. Once a file is damaged, it will no longer work as it should, so an app will not start or will give errors, a text file could be partially or completely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an admin, which makes it a serious problem for hosting servers as fails are more likely to happen on larger hard disks where significant volumes of information are located. If a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it's more than likely that the damaged file will be treated as a regular one and will be copied on all of the drives, making the damage permanent. A lot of the file systems that run on web servers these days often are not able to identify corrupted files immediately or they need time-consuming system checks through which the server is not operational.

No Data Corruption & Data Integrity in Cloud Hosting

We guarantee the integrity of the data uploaded in any cloud hosting account which is made on our cloud platform because we employ the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption using a unique checksum for every single file. We will store your info on multiple NVMe drives which operate in a RAID, so the same files will be present on several places concurrently. ZFS checks the digital fingerprint of all files on all the drives in real time and in the event that the checksum of any file differs from what it has to be, the file system swaps that file with an undamaged version from a different drive from the RAID. There's no other file system that uses checksums, so it is possible for data to get silently damaged and the bad file to be duplicated on all drives with time, but since this can never happen on a server using ZFS, you will not have to concern yourself with 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 our storage servers work with the state-of-the-art ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to guarantee the integrity of each file. When you upload content to your account, it'll be kept on a couple of redundant drives operating in a RAID i.e. the files will be the same across all drives. All the 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, and if it finds a mismatch, that will indicate that one of the copies is damaged, it will substitute that file with a good copy from one of the other disks. Even if there's an unforeseen blackout, the data on the servers won't get corrupted and there won't be any need for a time-consuming system check that other file systems perform following some malfunction, prolonging the time needed for the server to get back online. ZFS is the only file system that can truly protect your content from silent data corruption.
