Data corruption is the unintended modification of a file or the loss of info that usually occurs during reading or writing. The reason can be hardware or software malfunction, and consequently, a file may become partially or fully corrupted, so it'll no longer work correctly since its bits shall be scrambled or lost. An image file, for instance, will no longer present a real image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. When such an issue occurs and it is not noticed by the system or by an admin, the data will become corrupted silently and in case this happens on a drive that is a part of a RAID array where the info is synced between various different drives, the corrupted file shall be copied on all other drives and the damage will be permanent. A large number of widely used file systems either don't have real-time checks or don't have good ones that will detect an issue before the damage is done, so silent data corruption is a common problem on web hosting servers where huge amounts of information are kept.

No Data Corruption & Data Integrity in Website Hosting

If you host your websites in a website hosting account with our firm, you will not have to worry about your data ever getting corrupted. We can guarantee that since our cloud hosting platform uses the amazing ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each and every file. Any kind of data that you upload will be saved in a RAID i.e. simultaneously on multiple SSDs. All the file systems synchronize the files between the different drives with this type of a setup, but there's no real warranty that a file won't be corrupted. This may occur during the writing process on each drive and afterwards a bad copy may be copied on the rest of the drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all the drives instantly and in case a corrupted file is found, it's replaced with a good copy with the correct checksum from another drive. In this way, your data will continue to be intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be shielded from silent data corruption as all of our storage servers make use of the effective ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to ensure the integrity of each and every file. When you upload content to your account, it'll be saved on several redundant drives employed 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, so if it finds a mismatch, which will indicate that one of the copies is damaged, it'll replace that file with a good copy from one of the other drives. Even if there is an unforeseen power loss, the data on the servers will not be corrupted and there will not be any need for a time-consuming system check which other file systems perform following some malfunction, prolonging the time needed for the server to go back online. ZFS is the only file system which can truly protect your content from silent data corruption.
