The process of files getting corrupted due to some hardware or software failure is called data corruption and this is one of the main problems that hosting companies face because the larger a hard drive is and the more data 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 is damaged silently, so neither the particular file system, nor the administrators see a thing. Because of this, a damaged file will be handled as a standard one and if the HDD is part of a RAID, the file will be duplicated on all other disk drives. Theoretically, this is for redundancy, but in reality the damage will be even worse. When some file gets damaged, it will be partially or entirely 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 losing your website content. Although the most frequently used server file systems include various checks, they quite often fail to find a problem early enough or require a vast time period to check all the files and the web server will not be functional for the time being.

No Data Corruption & Data Integrity in Hosting

In case you host your websites in a hosting account with our firm, you won't have to worry about any of your data ever getting damaged. We can guarantee that as our cloud hosting platform employs the revolutionary ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for every single file. Any kind of info that you upload will be stored in a RAID i.e. simultaneously on many SSDs. All of the file systems synchronize the files between the different drives using this type of a setup, but there's no real guarantee that a file won't be corrupted. This may happen 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 compares the checksums of all files on all drives right away and if a corrupted file is identified, it's swapped with a good copy with the correct checksum from another drive. That way, your data will stay undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you purchase one of our semi-dedicated hosting plans, you will not need to be concerned about silent data corruption since we use ZFS - an advanced file system which monitors all of the files in real time. Whenever you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between several SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all of the copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done right away, so there will be no danger for any part of your content at any moment. In comparison, all the other file systems execute checks after a system failure, but since they don't use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy could be replicated on the other disks as well and you may lose crucial data. As this is not the case with ZFS, we're able to guarantee the integrity of each file you upload no matter what.
