The process of files being damaged as a result of some hardware or software failure is referred to as data corruption and this is one of the main problems that hosting companies face as the larger a hard disk drive is and the more data is filed on it, the much more likely it is for data to be corrupted. You can find various fail-safes, still often the info is damaged silently, so neither the file system, nor the admins notice anything. Consequently, a damaged file will be handled as a standard one and if the hard drive is a part of a RAID, that particular file will be copied on all other drives. In principle, this is done for redundancy, but in reality the damage will be worse. When a file gets corrupted, it will be partially or fully 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 will be impossible to unpack, so you risk losing your content. Although the most well-known server file systems have various checks, they quite often fail to detect a problem early enough or require a vast period of time to check all files and the web server will not be operational in the meantime.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data that you upload to your new shared hosting account will be guaranteed by the ZFS file system that we use on our cloud platform. The vast majority of internet hosting suppliers, including our company, use multiple hard drives to store content and considering that the drives work in a RAID, the exact same data is synchronized between the drives all the time. When a file on a drive gets damaged for reasons unknown, yet, it's likely that it will be duplicated on the other drives since other file systems don't have special checks for that. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for every single file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, which means that the bad copy will be substituted with a good one from another hard disk. Due to the fact that this happens instantly, there is no risk for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be resistant to silent data corruption since all our storage servers work with the advanced ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order to ensure the integrity of each file. When you upload content to your account, it will be saved on several redundant drives working in a RAID i.e. the files will be the same across all disk drives. All copies of a particular file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies quickly, so if it discovers a mismatch, that would indicate that one of the copies is damaged, it will substitute that file with a good copy from one of the other drives. Even if there is an unforeseen blackout, the data on the servers won't become corrupted and there won't be any need for a time-consuming system check which other file systems perform following some failure, lengthening the time needed for the server to get back online. ZFS is the file system that can truly protect your content from silent data corruption.
