The process of files being corrupted as a consequence of some hardware or software failure is known as data corruption and this is among the main problems which Internet hosting companies face because the larger a hard disk is and the more information is stored on it, the more likely it is for data to get corrupted. You'll find several fail-safes, yet often the information gets corrupted silently, so neither the file system, nor the administrators detect a thing. Because of this, a corrupted file will be treated as a good one and if the HDD is part of a RAID, that particular file will be duplicated on all other disk drives. In theory, this is for redundancy, but in practice the damage will get worse. The moment a given file gets corrupted, it will be partly or completely unreadable, which means that a text file will not be readable, an image file will display a random combination of colors in case it opens at all and an archive shall be impossible to unpack, so you risk losing your content. Although the most widely used server file systems include various checks, they frequently fail to find some problem early enough or require an extensive period of time to check all the files and the server will not be functional for the time being.

No Data Corruption & Data Integrity in Shared Web Hosting

In case you host your sites in a shared web hosting account from our company, you won't have to worry about any of your data ever getting corrupted. We can guarantee that since our cloud hosting platform works with the leading-edge ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for every single file. All data that you upload will be kept in a RAID i.e. simultaneously on a number of SSDs. All of the file systems synchronize the files between the separate drives with this kind of a setup, but there is no real warranty that a file will not get corrupted. This may happen during the writing process on any drive and then a corrupted copy can be copied on the rest of the drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all of the drives immediately and in case a corrupted file is identified, it's substituted with a good copy with the correct checksum from another drive. That way, your information will stay unharmed no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any risk of files getting damaged silently as the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system called ZFS. Its basic advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. As we keep all content on a number of SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has stored. In the event that there is a mismatch, the damaged copy is replaced with a good one from one of the other drives and considering that it happens right away, there is no chance that a corrupted copy could remain on our web servers or that it can be duplicated to the other hard drives in the RAID. None of the other file systems include this type of checks and furthermore, even during a file system check following an unexpected blackout, none of them will find silently corrupted files. In comparison, ZFS does not crash after an electrical power failure and the constant checksum monitoring makes a lenghty file system check unneeded.
