The process of files being damaged because of some hardware or software failure is known as data corruption and this is one of the main problems that hosting companies face since the larger a hard disk is and the more info is placed on it, the much more likely it is for data to get corrupted. You can find various fail-safes, still often the info is corrupted silently, so neither the particular file system, nor the administrators detect a thing. As a result, a damaged file will be handled as a standard one and if the hard disk drive is part of a RAID, the file will be duplicated on all other drives. In theory, this is for redundancy, but in practice the damage will get even worse. The moment a given file gets damaged, it will be partly or fully unreadable, which means that a text file will not be readable, an image file will show a random blend of colors if it opens at all and an archive will be impossible to unpack, so you risk losing your site content. Although the most popular server file systems have various checks, they often fail to detect a problem early enough or require a vast period of time in order to check all the files and the hosting server will not be functional for the time being.

No Data Corruption & Data Integrity in Cloud Hosting

The integrity of the data which you upload to your new cloud hosting account will be ensured by the ZFS file system which we use on our cloud platform. The vast majority of hosting suppliers, including our company, use multiple hard drives to store content and considering that the drives work in a RAID, exactly the same information is synchronized between the drives all the time. When a file on a drive becomes damaged for reasons unknown, yet, it's very likely that it will be duplicated on the other drives because alternative file systems do not feature special checks for this. Unlike them, ZFS employs a digital fingerprint, or a checksum, for each file. If a file gets damaged, its checksum won't match what ZFS has as a record for it, which means that the damaged copy will be swapped with a good one from another disk drive. Due to the fact that this happens right away, there's no possibility for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not need to deal with any silent data corruption issues whatsoever in case you get one of our semi-dedicated server packages due to the fact that the ZFS file system that we work with on our cloud hosting platform uses checksums in order to make sure that all files are intact all the time. A checksum is a unique digital fingerprint that is assigned to each and every file saved on a server. Due to the fact that we store all content on a number of drives simultaneously, the same file uses the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives in real time. In the event that 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 probability of the bad copy to be synchronized on the rest of the drives. ZFS is the only file system on the market that uses checksums, which makes it much more dependable than other file systems that are not able to detect silent data corruption and copy bad files across hard drives.
