The process of files getting damaged resulting from some hardware or software failure is known as data corruption and this is one of the main problems which web hosting companies face because the larger a hard drive is and the more info is stored on it, the more likely it is for data to be corrupted. There are different fail-safes, still often the data becomes corrupted silently, so neither the file system, nor the administrators see a thing. Because of this, a damaged file will be treated as a regular one and if the hard drive is a part of a RAID, the file will be duplicated on all other drives. Theoretically, this is done for redundancy, but in practice the damage will get worse. When some file gets damaged, it will be partially or fully unreadable, therefore 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, and you risk sacrificing your content. Although the most well-known server file systems have various checks, they often fail to discover some problem early enough or require an extensive period of time to check all files and the server will not be operational for the time being.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your websites in a shared hosting account with our company, you won't have to worry about any of your data ever getting corrupted. We can ensure that because our cloud hosting platform uses the leading-edge ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for every single file. Any kind of information that you upload will be kept in a RAID i.e. simultaneously on numerous SSDs. A lot of file systems synchronize the files between the different drives with this kind of a setup, but there's no real guarantee that a file won't get corrupted. This could occur at the time of the writing process on each drive and after that a damaged copy may be copied on all other drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all drives instantly and in case a corrupted file is found, it's replaced with a good copy with the correct checksum from some other drive. This way, your info will stay undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you go for one of our semi-dedicated server solutions, you won't have to be concerned about silent data corruption because we use ZFS - a high level file system that checks all files in real time. Whenever you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between multiple 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 happens instantly, so there will be no risk for any part of your content at any moment. In contrast, 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 will not detect silently corrupted files, so a corrupted copy can be replicated on the rest of the disks as well and you could lose crucial info. Since this isn't the case with ZFS, we are able to warrant the integrity of each file you upload no matter what.
