The process of files being damaged due to some hardware or software failure is called data corruption and this is among the main problems that Internet hosting companies face since the larger a hard disk drive is and the more info is stored on it, the more likely it is for data to be corrupted. You can find several fail-safes, but often the data becomes damaged silently, so neither the file system, nor the administrators notice a thing. Thus, a corrupted file will be treated as a standard one and if the hard drive is a part of a RAID, that particular file will be duplicated on all other disk drives. In theory, this is for redundancy, but in reality the damage will get even worse. Once some file gets damaged, it will be partially or entirely unreadable, so 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 will be impossible to unpack, so you risk sacrificing your website content. Although the most well-known server file systems feature various checks, they are likely to fail to identify a problem early enough or require a vast time period to check all the files and the web server will not be operational in the meantime.

No Data Corruption & Data Integrity in Shared Hosting

If you host your websites in a shared hosting account from our company, you won't need to worry about any of your data ever getting damaged. We can guarantee that as our cloud hosting platform employs the advanced ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for every single file. All data that you upload will be stored in a RAID i.e. simultaneously on many SSDs. All file systems synchronize the files between the different drives with this kind of a setup, but there's no real warranty that a file won't get corrupted. This could happen during the writing process on any drive and afterwards a bad copy can be copied on the rest of the drives. What is different on our platform is that ZFS examines the checksums of all files on all drives live and if a corrupted file is discovered, it is substituted with a good copy with the correct checksum from another drive. In this way, your data will stay intact 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 shielded from silent data corruption as all of our storage servers employ the state-of-the-art ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, to ensure the integrity of each and every file. When you upload content to your account, it'll be saved on a couple of redundant drives being employed in a RAID i.e. the files will be the same on all disk drives. All copies of a given file will feature the same checksum on all hard drives and ZFS will compare the checksums of the duplicates quickly, so if it registers a mismatch, that would indicate that one of the copies is damaged, it will replace that file with a good copy from one of the other disks. Even if there's an unexpected power loss, the data on the servers won't become corrupted and there will not be any need for a time-consuming system check which other file systems perform following some breakdown, prolonging the time needed for the server to return online. ZFS is the sole file system which can really protect your content from silent data corruption.
