The process of files being corrupted as a result of some hardware or software failure is called data corruption and this is among the main problems which web hosting companies face as the larger a hard drive is and the more data is stored on it, the much more likely it is for data to get corrupted. You will find different fail-safes, yet often the data gets corrupted silently, so neither the particular file system, nor the admins notice anything. Consequently, a damaged file will be treated as a regular one and if the hard disk drive is part of a RAID, that file will be duplicated on all other drives. In principle, this is for redundancy, but in practice the damage will get even worse. When a given file gets damaged, it will be partly or completely unreadable, so 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 shall be impossible to unpack, and you risk sacrificing your content. Although the most popular server file systems include various checks, they quite often fail to identify some problem early enough or require a vast time period to check all of the files and the web hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your sites in a cloud hosting account with our company, you do not need to worry about your data ever getting corrupted. We can ensure that as our cloud hosting platform employs the revolutionary ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for every single file. Any data that you upload will be kept in a RAID i.e. simultaneously on numerous NVMe drives. All the file systems synchronize the files between the separate drives with such a setup, but there's no real guarantee that a file will not be corrupted. This could happen during the writing process on any drive and after that a bad copy may 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 immediately and when a corrupted file is located, it is replaced with a good copy with the correct checksum from some other drive. In this way, your info will remain unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you acquire one of our semi-dedicated server solutions, you won't have to worry about silent file corruption as we use ZFS - a high level file system that keeps track of all the files in real time. Each time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This 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 another drive. This happens in real time, so there will be no risk for any part of your content at any time. By comparison, other file systems carry out checks only after a system failure, but since they do not use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a bad copy could be replicated on the remaining disks as well and you can lose crucial information. Because this is not the case with ZFS, we guarantee the integrity of each and every file you upload no matter what.
