The process of files being damaged as a result of some hardware or software failure is called data corruption and this is among the main problems that hosting companies face since the larger a hard disk is and the more data is kept on it, the much more likely it is for data to get corrupted. You'll find a couple of fail-safes, yet often the data gets corrupted silently, so neither the file system, nor the administrators detect a thing. Because of this, a bad file will be handled as a standard one and if the hard disk is a part of a RAID, the file will be duplicated on all other drives. In theory, this is for redundancy, but in practice the damage will be even worse. The moment some file gets corrupted, it will be partly or fully unreadable, so a text file will no longer be readable, an image file will present a random mix of colors if it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your website content. Although the most commonly used server file systems include various checks, they quite often fail to identify a problem early enough or require a long amount of time to check all the files and the web server will not be functional for the time being.
No Data Corruption & Data Integrity in Shared Hosting
In case you host your sites in a shared hosting
account with our firm, you don't need to worry about your data ever getting damaged. We can ensure that since our cloud hosting platform employs the reliable ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for every single file. All of the information that you upload will be kept in a RAID i.e. simultaneously on a large number of SSDs. All of the file systems synchronize the files between the separate drives with this type of a setup, but there is no real warranty that a file will not get corrupted. This can occur during the writing process on any drive and after that a corrupted copy can be copied on all other drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all the drives instantly and if a corrupted file is discovered, it's substituted with a good copy with the correct checksum from another drive. By doing this, your information will remain intact no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
If you buy one of our semi-dedicated server
plans, you won't have to worry about silent data corruption as we use ZFS - a high level file system which monitors all of the files in real time. Every time 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 multiple SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all 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 in real time, so there will be no threat for any part of your content at any moment. In contrast, alternative file systems execute checks after a system malfunction, 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 other drives as well and you may lose important info. Since this is not the case with ZFS, we warrant the integrity of each file you upload no matter what.
