The process of files being damaged resulting from some hardware or software failure is called data corruption and this is among the main problems that Internet hosting companies face since the larger a hard drive is and the more data is stored on it, the more likely it is for data to become corrupted. You'll find different fail-safes, but often the info becomes corrupted silently, so neither the file system, nor the admins notice a thing. Thus, a bad file will be handled as a regular one and if the hard disk is part of a RAID, that particular file will be copied on all other disk drives. In principle, this is for redundancy, but in practice the damage will be even worse. Once some file gets damaged, it will be partially or completely unreadable, so a text file will not be readable, an image file will display a random combination of colors if it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your content. Although the most commonly used server file systems feature various checks, they quite often fail to detect a problem early enough or require an extensive amount of time to be able to check all of the files and the server will not be operational in the meantime.
No Data Corruption & Data Integrity in Shared Web Hosting
In case you host your Internet sites in a shared web hosting
account from our firm, you won't have to worry about any of your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform works with the reliable ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each and every file. Any kind of data that you upload will be saved in a RAID i.e. simultaneously on numerous SSDs. All file systems synchronize the files between the separate drives with such a setup, but there is no real warranty that a file will not get corrupted. This could occur at the time of the writing process on each drive and afterwards a bad copy can be copied on the rest of the 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 found, it's substituted with a good copy with the correct checksum from another drive. In this way, your info will stay unharmed no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not encounter any silent data corruption issues whatsoever should you obtain one of our semi-dedicated hosting
solutions as the ZFS file system that we use on our cloud hosting platform uses checksums to guarantee that all files are undamaged at all times. A checksum is a unique digital fingerprint which is assigned to each and every file kept on a server. As we store all content on multiple drives simultaneously, the same file has the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives in real time. When it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy right away, avoiding any probability of the corrupted copy to be synchronized on the rest of the hard drives. ZFS is the only file system you can find which uses checksums, which makes it much more dependable than other file systems which cannot detect silent data corruption and duplicate bad files across hard drives.
