The process of files getting damaged caused by some hardware or software failure is called data corruption and this is among the main problems that hosting companies face as the larger a hard disk is and the more data is stored on it, the more likely it is for data to become corrupted. There're a couple of fail-safes, but often the data is corrupted silently, so neither the file system, nor the admins see a thing. Thus, a damaged file will be treated as a standard one and if the HDD is a part of a RAID, that file will be duplicated on all other drives. In principle, this is done for redundancy, but in reality the damage will be worse. When some file gets corrupted, it will be partly or entirely unreadable, which means that a text file will no longer be readable, an image file will show a random combination of colors in case it opens at all and an archive will be impossible to unpack, so you risk sacrificing your content. Although the most frequently used server file systems feature various checks, they quite often fail to find a problem early enough or require a vast time period in order to check all of the files and the server will not be functional in the meantime.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your sites in a cloud hosting account from our company, you don't need to worry about your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform employs the cutting-edge ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for every single file. All of the info that you upload will be saved in a RAID i.e. simultaneously on a number of SSD drives. All file systems synchronize the files between the separate drives using this kind of a setup, but there is no real guarantee that a file won't be corrupted. This can happen throughout the writing process on any drive and after that a corrupted copy can be copied on the rest of the 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 in the event that a corrupted file is discovered, it's replaced with a good copy with the correct checksum from some other drive. That 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 buy one of our semi-dedicated server plans, you will not have to be concerned about silent data corruption since we use ZFS - a high level file system that keeps track of all files in real time. Each time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between multiple SSD drives for redundancy, so if a drive fails, the other ones will take over. 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 another drive. This happens immediately, so there will be no threat for any part of your content at any time. In comparison, alternative file systems execute checks only after a system malfunction, but since they don't use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a corrupted copy may be replicated on the rest of the drives as well and you may lose critical info. Because this isn't the case with ZFS, we're able to warrant the integrity of each file you upload no matter what.
