The process of files getting damaged resulting from some hardware or software failure is called data corruption and this is one of the main problems which web hosting companies face since the larger a hard disk drive is and the more info is kept on it, the much more likely it is for data to become corrupted. You can find various fail-safes, still often the information becomes corrupted silently, so neither the file system, nor the administrators detect anything. Consequently, a corrupted file will be treated as a good one and if the hard disk is a part of a RAID, the file will be duplicated on all other drives. In theory, this is done for redundancy, but in reality the damage will get even worse. Once a file gets damaged, it will be partially or fully unreadable, which means that a text file will not be readable, an image file will present a random mix of colors if it opens at all and an archive will be impossible to unpack, and you risk losing your content. Although the most widespread server file systems feature various checks, they frequently fail to discover a problem early enough or require a vast time period in order to check all of the files and the web hosting server will not be functional in the meantime.

No Data Corruption & Data Integrity in Cloud Website Hosting

In case you host your Internet sites in a cloud website hosting account with our company, you don't need to worry about any of your data ever getting corrupted. We can ensure that due to the fact that our cloud hosting platform uses the revolutionary ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each and every file. All the data that you upload will be stored in a RAID i.e. simultaneously on multiple SSD drives. Many file systems synchronize the files between the different drives with this kind of a setup, but there is no real warranty that a file won't get corrupted. This can happen at the time of the writing process on any drive and then a corrupted copy may be copied on all other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all drives immediately and in case a corrupted file is discovered, it's replaced with a good copy with the correct checksum from some other drive. In this way, your information will remain undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you get one of our semi-dedicated server packages, you will not need to worry about silent file corruption since we use ZFS - a high level file system that keeps track of all the files in real time. Whenever 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 synced between a couple of SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all the 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 immediately, so there will be no threat for any part of your content at any time. By comparison, all the other file systems execute checks only 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 bad copy can be replicated on the other drives as well and you could lose important data. As this is not the case with ZFS, we're able to guarantee the integrity of every single file you upload no matter what.
