The process of files being damaged because of some hardware or software failure is referred to as data corruption and this is one of the main problems that hosting companies face since the larger a hard disk is and the more information is stored on it, the more likely it is for data to be corrupted. You will find different fail-safes, still often the information gets corrupted silently, so neither the file system, nor the administrators notice a thing. Because of this, a bad file will be handled as a standard one and if the hard drive is part of a RAID, that particular file will be duplicated on all other drives. In theory, this is done for redundancy, but in practice the damage will be even worse. The moment a file gets damaged, it will be partially or completely unreadable, which means that a text file will no longer be readable, an image file will present a random blend of colors if it opens at all and an archive will be impossible to unpack, so you risk sacrificing your website content. Although the most frequently used server file systems feature various checks, they are likely to fail to find some problem early enough or require a long amount of time to check all the files and the server will not be operational in the meantime.
No Data Corruption & Data Integrity in Shared Hosting
If you host your sites in a shared hosting account with our firm, you will not have to worry about your data ever getting corrupted. We can ensure that since our cloud hosting platform works with the revolutionary ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for every single file. All the info that you upload will be kept in a RAID i.e. simultaneously on numerous SSD drives. All the file systems synchronize the files between the separate drives using this kind of a setup, but there's no real guarantee that a file won't get corrupted. This could happen during the writing process on each drive and after that a corrupted copy may be copied on the other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all of the drives live and in the event that a corrupted file is located, it's replaced with a good copy with the correct checksum from some other drive. This way, your information will continue to be undamaged no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
If you purchase one of our semi-dedicated server plans, you won't have to worry about silent file corruption as we use ZFS - an advanced file system that monitors 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. The file will be synchronized 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 corrupted copy, it replaces it with a healthy one from a different drive. This is done immediately, so there will be no danger for any part of your content at any moment. In comparison, alternative file systems carry out checks only after a system breakdown, but since they do not use anything similar to the checksums that ZFS uses, they cannot detect silently corrupted files, so a corrupted copy may be replicated on the remaining drives as well and you can lose critical information. Because this isn't the case with ZFS, we are able to warrant the integrity of each file you upload no matter what.
