The process of files being corrupted as a consequence of some hardware or software failure is called data corruption and this is one of the main problems that web hosting companies face as the larger a hard disk is and the more info is stored on it, the much more likely it is for data to become corrupted. You'll find a couple of fail-safes, but often the information gets corrupted silently, so neither the particular file system, nor the admins detect a thing. Consequently, a bad file will be handled as a good one and if the HDD is part of a RAID, that particular file will be duplicated on all other disk drives. In principle, this is done for redundancy, but in reality the damage will be even worse. Once a given file gets corrupted, it will be partially or completely unreadable, which means that a text file will not be readable, an image file will display a random mix of colors if it opens at all and an archive will be impossible to unpack, and you risk sacrificing your site content. Although the most frequently used server file systems include various checks, they are likely to fail to identify some problem early enough or require a long period of time to be able to check all of the files and the web server will not be functional in the meantime.

No Data Corruption & Data Integrity in Website Hosting

We guarantee the integrity of the data uploaded in each and every website hosting account that is generated on our cloud platform because we employ the advanced ZFS file system. The aforementioned 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 data on a number of SSD drives that function in a RAID, so identical files will be present on several places at the same time. ZFS checks the digital fingerprint of all the files on all the drives in real time and if the checksum of any file is different from what it has to be, the file system replaces that file with a healthy copy from some other drive inside the RAID. There's no other file system which uses checksums, so it's possible for data to be silently damaged and the bad file to be duplicated on all drives over time, but since this can never happen on a server running ZFS, you don't have to worry about the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you purchase one of our semi-dedicated hosting solutions, you will not need to be concerned about silent data corruption since we use ZFS - an advanced file system which keeps track of all the files in real time. Each time you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between several SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and when 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. In comparison, all the other file systems perform checks after a system failure, but since they don't use anything similar to the checksums that ZFS uses, they cannot detect silently corrupted files, so a corrupted copy may be replicated on the other disks as well and you may lose precious data. Because this is not the case with ZFS, we guarantee the integrity of each file you upload no matter what.
