The process of files getting damaged owing to some hardware or software failure is referred to as data corruption and this is one of the main problems which web hosting companies face because the larger a hard disk drive is and the more info is placed on it, the more likely it is for data to be corrupted. You'll find a couple of fail-safes, still often the data is damaged silently, so neither the particular file system, nor the administrators notice a thing. Because of this, a damaged file will be handled as a good one and if the hard disk is a part of a RAID, that file will be copied on all other disk drives. Theoretically, this is done for redundancy, but in practice the damage will get even worse. When a file gets corrupted, it will be partially or fully unreadable, so a text file will no longer be readable, an image file will show a random mix of colors in case it opens at all and an archive shall be impossible to unpack, so you risk losing your website content. Although the most widespread server file systems include various checks, they quite often fail to discover some problem early enough or require a vast amount of time to check all files and the web hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Shared Web Hosting

In case you host your sites in a shared web hosting account from our firm, you don't need to worry about your data ever getting damaged. We can ensure that as our cloud hosting platform employs the reliable ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for every single file. All the information that you upload will be kept in a RAID i.e. simultaneously on numerous NVMes. All of the file systems synchronize the files between the different drives using this kind of a setup, but there's no real guarantee that a file will not be corrupted. This may occur at the time of the writing process on each drive and then a damaged copy may be copied on the other drives. What is different on our platform is that ZFS examines the checksums of all files on all the drives instantly and if a corrupted file is discovered, it is swapped with a good copy with the correct checksum from some other drive. By doing this, your information will remain intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not have to deal with any kind of silent data corruption issues whatsoever if you get one of our semi-dedicated server packages since the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to make sure that all the files are undamaged all of the time. A checksum is a unique digital fingerprint which is given to each and every file kept on a server. As we store all content on a number of drives at the same time, the same file has the same checksum on all of the 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 right away, avoiding any chance of the damaged copy to be synchronized on the other hard disks. ZFS is the sole file system out there that uses checksums, which makes it far superior to other file systems which are unable to identify silent data corruption and duplicate bad files across drives.
