Data corruption is the unintentional modification of a file or the loss of information which usually occurs during reading or writing. The reason may be hardware or software malfunction, and because of this, a file may become partially or entirely corrupted, so it'll no longer work as it should as its bits will be scrambled or lacking. An image file, for instance, will no longer display a real image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. In case such a problem occurs and it's not noticed by the system or by an administrator, the data will get corrupted silently and when this happens on a disk drive that's a part of a RAID array where the info is synchronized between various drives, the corrupted file will be duplicated on all of the other drives and the damage will become permanent. A large number of frequently used file systems either don't have 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 issue on hosting servers where large volumes of information are kept.

No Data Corruption & Data Integrity in Cloud Hosting

We warrant the integrity of the information uploaded in any cloud hosting account that is made on our cloud platform due to the fact that we use the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption thanks to a unique checksum for each and every file. We will store your info on a number of SSD drives that work in a RAID, so the very same files will be accessible on several places concurrently. 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 is different from what it needs to be, the file system replaces that file with a healthy copy from another drive in the RAID. No other file system uses checksums, so it's possible for data to get silently damaged and the bad file to be reproduced on all drives with time, but since this can never happen on a server using ZFS, you won't 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 protected against silent data corruption because all of our storage servers make use of the efficient ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, in order to verify the integrity of every single file. When you upload content to your account, it will be kept on a couple of redundant drives 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 disks and ZFS will compare the checksums of the duplicates right away, so if it identifies a mismatch, that 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 power loss, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check that 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 really protect your content from silent data corruption.
