The process of files being damaged resulting from some hardware or software failure is known as data corruption and this is among the main problems that Internet hosting companies face since the larger a hard disk is and the more info is filed on it, the much more likely it is for data to get corrupted. There are various fail-safes, still often the information is damaged silently, so neither the file system, nor the admins see a thing. Thus, a corrupted file will be handled as a good one and if the hard drive is part of a RAID, the file will be duplicated on all other drives. Theoretically, this is done for redundancy, but in reality the damage will be even worse. Once a file gets damaged, it will be partially or completely unreadable, so 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 will be impossible to unpack, so you risk sacrificing your website content. Although the most popular server file systems feature various checks, they are likely to fail to identify some problem early enough or require an extensive period of time in order to check all of the files and the web hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your Internet sites in a shared hosting account from our company, you will not have to worry about any of your data ever getting damaged. We can guarantee that because our cloud hosting platform uses the advanced ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for every single file. Any information that you upload will be kept in a RAID i.e. simultaneously on a number of NVMes. All file systems synchronize the files between the different drives with this type of a setup, but there's no real guarantee that a file won't be corrupted. This may occur throughout the writing process on any drive and after that a corrupted copy can be copied on the other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all of the drives live and in the event that a corrupted file is found, it is swapped with a good copy with the correct checksum from some other drive. In this way, your information will stay unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you acquire one of our semi-dedicated hosting solutions, you will not have to be concerned about silent file corruption since we use ZFS - a high level file system which checks 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. The file will be synchronized between several NVMe drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done in real time, so there will be no threat for any part of your content at any moment. In comparison, other file systems perform checks after a system failure, 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 may be replicated on the rest of the disks as well and you can lose crucial info. Since this isn't the case with ZFS, we are able to guarantee the integrity of every single file you upload no matter what.
