The process of files being damaged as a result of some hardware or software failure is referred to as data corruption and this is one of the main problems that web hosting companies face because the larger a hard disk drive is and the more info is kept on it, the much more likely it is for data to get corrupted. There are various fail-safes, but often the info gets corrupted silently, so neither the file system, nor the admins notice anything. Because of this, a bad file will be treated as a regular one and if the hard disk drive is part of a RAID, that particular file will be copied on all other drives. Theoretically, this is done for redundancy, but in reality the damage will be worse. When a file gets damaged, it will be partly or entirely unreadable, therefore a text file will not be readable, an image file will present a random combination of colors in case it opens at all and an archive shall be impossible to unpack, so you risk losing your content. Although the most well-known server file systems have various checks, they are likely to fail to identify a problem early enough or require a long amount of time to be able to check all of the files and the server will not be operational for the time being.

No Data Corruption & Data Integrity in Cloud Web Hosting

We guarantee the integrity of the data uploaded in each and every cloud web hosting account that is created on our cloud platform as we employ 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 file. We will store your info on multiple SSD drives that operate in a RAID, so exactly the same files will be present on several places at once. ZFS checks the digital fingerprint of all the files on all drives in real time and in the event that the checksum of any file differs from what it needs to be, the file system swaps that file with an undamaged version from some other drive from the RAID. No other file system uses checksums, so it is possible for data to be silently corrupted and the bad file to be duplicated on all drives over time, but since this can never happen on a server running ZFS, you won't have to concern yourself with the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you buy one of our semi-dedicated hosting packages, you won't need to be concerned about silent file corruption because we use ZFS - an advanced file system which monitors all the 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. That file will be synced between a number of SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all the copies on the different drives and if it detects a corrupted copy, it replaces it with a healthy one from a different drive. This happens instantly, so there will be no danger for any part of your content at any time. By comparison, alternative file systems perform checks only after a system malfunction, but since they don't use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a corrupted copy could be replicated on the other disks as well and you can lose precious info. Because this is not the case with ZFS, we're able to guarantee the integrity of each file you upload no matter what.
