The process of files being corrupted due to some hardware or software failure is referred to as data corruption and this is among the main problems which Internet hosting companies face since the larger a hard disk is and the more info is filed on it, the more likely it is for data to become corrupted. You will find a couple of fail-safes, yet often the information becomes corrupted silently, so neither the file system, nor the admins notice anything. As a result, a damaged file will be treated as a good one and if the hard disk drive is a part of a RAID, that particular file will be duplicated on all other drives. In theory, this is for redundancy, but in reality the damage will get even worse. Once some file gets damaged, it will be partially or entirely unreadable, so 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 website content. Although the most popular server file systems include various checks, they are likely to fail to identify some problem early enough or require a vast amount of time to check all the files and the hosting server will not be functional for the time being.
No Data Corruption & Data Integrity in Website Hosting
If you host your websites in a 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 employs the revolutionary ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each and every file. Any information that you upload will be saved in a RAID i.e. simultaneously on many different SSD drives. All of the file systems synchronize the files between the different drives using this type of a setup, but there's no real warranty that a file will not get corrupted. This can occur at the time of the writing process on each drive and after that a damaged copy can be copied on all other drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all of the drives immediately and in case a corrupted file is found, it's replaced with a good copy with the correct checksum from some other drive. By doing this, your info will stay intact no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
If you go for one of our semi-dedicated server solutions, you will not have to be concerned about silent data corruption as we use ZFS - a high level file system which keeps track of all of 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. That file will be synchronized between a number 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 instantly, so there will be no risk for any part of your content at any time. By comparison, alternative file systems carry out checks after a system malfunction, but since they don't use anything similar to the checksums which ZFS uses, they won't detect silently corrupted files, so a corrupted copy could be replicated on the rest of the drives as well and you could lose precious data. Because this isn't the case with ZFS, we guarantee the integrity of every single file you upload no matter what.
