The process of files getting corrupted owing to 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 drive is and the more data is placed on it, the much more likely it is for data to be corrupted. You will find various fail-safes, yet often the info becomes damaged silently, so neither the particular file system, nor the administrators notice a thing. Thus, a bad file will be handled as a regular one and if the hard disk is a part of a RAID, the file will be duplicated on all other disk drives. In principle, this is for redundancy, but in reality the damage will be even worse. The moment some file gets damaged, it will be partly or entirely unreadable, therefore a text file will no longer be readable, an image file will present a random mix of colors in case it opens at all and an archive shall be impossible to unpack, and you risk losing your content. Although the most commonly used server file systems have various checks, they are likely to fail to discover a problem early enough or require a long amount of time in order to check all of the files and the web server will not be functional in the meantime.
No Data Corruption & Data Integrity in Shared Website Hosting
We guarantee the integrity of the information uploaded in each and every shared website hosting account which is made on our cloud platform because we use the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption thanks to a unique checksum for every single file. We'll store your information on multiple SSD drives that operate in a RAID, so exactly the same files will be present on several places concurrently. ZFS checks the digital fingerprint of all the files on all the drives in real time and in the event that the checksum of any file differs from what it should be, the file system replaces that file with an undamaged copy from a different drive inside the RAID. There's no other file system which uses checksums, so it's easy for data to be silently corrupted and the bad file to be replicated on all drives with time, but since this can never happen on a server using ZFS, you don't have to worry about the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Servers
If you acquire one of our semi-dedicated server solutions, you will not need to be concerned about silent file corruption because we use ZFS - a high level file system that monitors all files in real time. Whenever 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 a number of SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all of 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 happens right away, so there will be no threat for any part of your content at any time. By comparison, all of the other file systems carry out checks after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy may be replicated on the rest of the disks as well and you may lose crucial info. Because this isn't the case with ZFS, we guarantee the integrity of every single file you upload no matter what.
