Data corruption is the accidental transformation of a file or the losing of info that often occurs during reading or writing. The reason may be hardware or software failure, and consequently, a file can become partially or fully corrupted, so it'll no longer function as it should since its bits will be scrambled or lacking. An image file, for instance, will no longer show an actual image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. In case this kind of an issue appears and it is not recognized by the system or by an admin, the data will get corrupted silently and if this happens on a drive that is a part of a RAID array where the information is synced between various different drives, the corrupted file shall be replicated on all other drives and the damage will become permanent. A number of frequently used file systems either do not feature real-time checks or do not have good ones that will detect an issue before the damage is done, so silent data corruption is a rather common matter on web hosting servers where large amounts of information are stored.

No Data Corruption & Data Integrity in Web Hosting

We warrant the integrity of the information uploaded in each and every web hosting account which is made on our cloud platform because we use the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption thanks to a unique checksum for each and every file. We'll store your data on a large number of NVMe drives that operate in a RAID, so the very same files will be available on several places concurrently. ZFS checks the digital fingerprint of all of the files on all the drives in real time and in case the checksum of any file differs from what it has to be, the file system swaps that file with an undamaged version from some other drive within the RAID. No other file system uses checksums, so it is easy for data to be silently corrupted and the bad file to be duplicated on all drives with time, but since this can never happen on a server running ZFS, you won't have to concern yourself with the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you purchase one of our semi-dedicated server packages, you won't need to be concerned about silent file corruption since we use ZFS - an advanced file system that keeps track of all files in real time. Each time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between multiple NVMe drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and if it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done right away, so there will be no risk for any part of your content at any time. By comparison, other file systems carry out checks after a system malfunction, but since they do not use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy may be replicated on the rest of the disks as well and you may lose crucial info. Because this isn't the case with ZFS, we are able to warrant the integrity of each file you upload no matter what.
