The process of files being damaged due to some hardware or software failure is known as data corruption and this is among the main problems which Internet hosting companies face since the larger a hard drive is and the more information is kept on it, the more likely it is for data to be corrupted. You will find a couple of fail-safes, yet often the data is corrupted silently, so neither the particular file system, nor the administrators see a thing. Because of this, a damaged file will be treated as a standard one and if the hard disk is a part of a RAID, that particular file will be copied on all other disk drives. In principle, this is done for redundancy, but in practice the damage will be worse. Once a given file gets corrupted, it will be partially or completely unreadable, therefore a text file will not be readable, an image file will present a random combination of colors in case it opens at all and an archive will be impossible to unpack, and you risk sacrificing your site content. Although the most widespread server file systems include various checks, they are likely to fail to detect a problem early enough or require an extensive time period in order to check all files and the hosting server will not be functional in the meantime.
No Data Corruption & Data Integrity in Web Hosting
In case you host your websites in a web hosting
account from our company, you won't need to worry about any of your data ever getting damaged. We can ensure that because our cloud hosting platform uses the leading-edge ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each file. All the information that you upload will be saved in a RAID i.e. simultaneously on numerous SSDs. A lot of file systems synchronize the files between the separate drives with such a setup, but there's no real warranty that a file won't get corrupted. This may occur at the time of the writing process on each drive and afterwards a corrupted copy can be copied on all other drives. What is different on our platform is that ZFS examines the checksums of all files on all drives in real time and if a corrupted file is discovered, it is substituted with a good copy with the correct checksum from some other drive. That way, your information will stay unharmed no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be protected against silent data corruption because all our storage servers employ the efficient ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to guarantee the integrity of each file. When you upload content to your account, it'll be kept on a couple of redundant drives being employed in a RAID i.e. the files will be the same across all drives. All the copies of a given file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates quickly, so if it finds a mismatch, that would indicate that one of the copies is damaged, it will replace that file with a healthy copy from one of the other disks. Even if there is an unexpected power loss, the data on the servers won't get corrupted and there won't be any need for a time-consuming system check which other file systems perform after some breakdown, prolonging the time needed for the server to go back online. ZFS is the only file system that can really protect your content from silent data corruption.
