The process of files getting damaged due to some hardware or software failure is referred to as data corruption and this is one of the main problems that hosting companies face because the larger a hard disk drive is and the more information is placed on it, the much more likely it is for data to get corrupted. There are various fail-safes, yet often the info is corrupted silently, so neither the particular file system, nor the admins detect a thing. As a result, a bad file will be treated as a good one and if the hard disk drive is a part of a RAID, that file will be duplicated on all other drives. In theory, this is for redundancy, but in reality the damage will be even worse. When some file gets corrupted, it will be partly or completely unreadable, which means that a text file will no longer be readable, an image file will present a random blend of colors in case it opens at all and an archive shall be impossible to unpack, so you risk losing your content. Although the most commonly used server file systems feature various checks, they often fail to find a problem early enough or require an extensive period of time to be able to check all of the files and the server will not be functional for the time being.
No Data Corruption & Data Integrity in Cloud Hosting
If you host your sites in a cloud hosting account from our firm, you will not have to worry about any of your data ever getting corrupted. We can guarantee that as our cloud hosting platform works with the reliable ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each file. All information that you upload will be stored in a RAID i.e. simultaneously on a number of SSD drives. All of the file systems synchronize the files between the different drives with this type of a setup, but there is no real guarantee that a file won't be corrupted. This may occur at the time of the writing process on each drive and afterwards a bad copy can be copied on all other drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all of the drives right away and in case a corrupted file is discovered, it is replaced with a good copy with the correct checksum from another drive. That way, your info will continue to be intact no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You won't need to deal with any silent data corruption issues in case you acquire one of our semi-dedicated hosting packages as the ZFS file system that we employ 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. Because we store all content on multiple drives simultaneously, the same file uses the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives right away. In the event that it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy without delay, avoiding any chance of the damaged copy to be synchronized on the rest of the hard disks. ZFS is the only file system out there that uses checksums, which makes it much more dependable than other file systems which are not able to identify silent data corruption and copy bad files across drives.
