The process of files being damaged as a consequence of some hardware or software failure is known as data corruption and this is one of the main problems which web hosting companies face as the larger a hard drive is and the more info is placed on it, the much more likely it is for data to become corrupted. There're various fail-safes, still often the information becomes damaged silently, so neither the file system, nor the administrators see anything. Consequently, a damaged file will be treated as a standard one and if the hard drive is part of a RAID, that particular file will be duplicated on all other disk drives. In principle, this is for redundancy, but in practice the damage will be even worse. Once a file gets corrupted, it will be partially or entirely unreadable, which means that a text file will not be readable, an image file will present a random mix of colors if it opens at all and an archive will be impossible to unpack, and you risk sacrificing your site content. Although the most popular server file systems include various checks, they frequently fail to discover a problem early enough or require an extensive time period in order to check all files and the web server will not be functional in the meantime.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your Internet sites in a cloud hosting account from our firm, you won't have to worry about any of your data ever getting damaged. We can guarantee that because our cloud hosting platform employs the state-of-the-art ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each and every file. All the information that you upload will be kept in a RAID i.e. simultaneously on many different SSD drives. Many file systems synchronize the files between the separate drives using this kind of a setup, but there is no real guarantee that a file won't be corrupted. This may happen during the writing process on each drive and then a corrupted copy may be copied on all other drives. What makes the difference on our platform is that ZFS analyzes the checksums of all files on all the drives instantly and in the event that a corrupted file is found, it is replaced with a good copy with the correct checksum from some other drive. By doing this, your data will remain unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You won't experience any silent data corruption issues in case you obtain one of our semi-dedicated hosting plans since the ZFS file system that we use on our cloud hosting platform uses checksums to ensure that all of your files are intact at all times. A checksum is a unique digital fingerprint that is assigned to each and every file saved on a server. As we store all content on multiple drives at the same time, the same file uses the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. When 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 right away, avoiding any probability of the bad copy to be synchronized on the other drives. ZFS is the only file system you can find which uses checksums, which makes it much more reliable than other file systems that are not able to identify silent data corruption and duplicate bad files across drives.
