The process of files getting corrupted caused by some hardware or software failure is referred to as data corruption and this is among the main problems which web hosting companies face since the larger a hard disk drive is and the more information is kept on it, the much more likely it is for data to get corrupted. There are various fail-safes, yet often the information gets damaged silently, so neither the file system, nor the administrators see anything. Consequently, a bad file will be handled as a standard one and if the hard disk is a part of a RAID, that particular file will be copied on all other drives. Theoretically, this is done for redundancy, but in practice the damage will be even worse. The moment some file gets damaged, it will be partly or fully unreadable, which means that a text file will not be readable, an image file will present a random combination of colors if it opens at all and an archive shall be impossible to unpack, and you risk losing your website content. Although the most widely used server file systems include various checks, they frequently fail to discover a problem early enough or require an extensive amount of time to check all files and the web hosting server will not be operational for the time being.
No Data Corruption & Data Integrity in Shared Hosting
If you host your sites in a shared hosting
account from our firm, you will not have to worry about your data ever getting damaged. We can guarantee that because our cloud hosting platform uses the outstanding ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each file. All of the information that you upload will be kept in a RAID i.e. simultaneously on many SSDs. Many file systems synchronize the files between the different drives using such a setup, but there's no real guarantee that a file won't get corrupted. This may happen at the time of the writing process on any drive and afterwards a corrupted copy may 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 in real time and in case a corrupted file is found, it is substituted with a good copy with the correct checksum from some other drive. This way, your info will stay intact no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not experience any silent data corruption issues whatsoever in case you buy one of our semi-dedicated hosting
solutions because the ZFS file system that we work with on our cloud hosting platform uses checksums to ensure that all of the files are undamaged all the time. A checksum is a unique digital fingerprint that is given to each and every file kept on a server. Because we store all content on multiple drives simultaneously, the same file has the same checksum on all 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 has to be, it replaces that file with a healthy copy right away, avoiding any chance of the damaged copy to be synchronized on the remaining drives. ZFS is the only file system you can get that uses checksums, which makes it far superior to other file systems that are not able to detect silent data corruption and copy bad files across drives.
