The process of files being damaged because of some hardware or software failure is called data corruption and this is among the main problems that Internet hosting companies face because the larger a hard disk drive is and the more data is placed on it, the much more likely it is for data to be corrupted. You will find different fail-safes, but often the data becomes damaged silently, so neither the particular file system, nor the admins notice a thing. Because of this, a damaged file will be handled as a standard one and if the hard disk drive is part of a RAID, that particular file will be copied on all other disk drives. In theory, this is for redundancy, but in reality the damage will get worse. The moment a given file gets corrupted, it will be partly or fully unreadable, so a text file will not be readable, an image file will show a random mix of colors if it opens at all and an archive will be impossible to unpack, so you risk losing your website content. Although the most widespread server file systems have various checks, they often fail to identify some problem early enough or require an extensive time period in order to check all files and the web hosting server will not be functional in the meantime.

No Data Corruption & Data Integrity in Web Hosting

If you host your sites in a web hosting account with our firm, you don't have to worry about your data ever getting damaged. We can guarantee that due to the fact that our cloud hosting platform uses the amazing ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each and every file. All info that you upload will be kept in a RAID i.e. simultaneously on a large number of SSD drives. A lot of file systems synchronize the files between the separate drives with this kind of a setup, but there is no real warranty that a file won't be corrupted. This can occur at the time of the writing process on each drive and then a bad copy may be copied on all other drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all the drives immediately and in the event that a corrupted file is discovered, it is swapped with a good copy with the correct checksum from another drive. That way, your data will remain undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't experience any kind of silent data corruption issues should you purchase one of our semi-dedicated server packages as the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to guarantee that all of your files are intact all the time. A checksum is a unique digital fingerprint that is given to each and every file saved on a server. Due to the fact that we store all content on a number of drives at the same time, the same file uses the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives in real time. If 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 probability of the damaged copy to be synchronized on the remaining hard drives. ZFS is the sole file system on the market that uses checksums, which makes it far superior to other file systems which are unable to detect silent data corruption and copy bad files across drives.
