The process of files being damaged resulting from some hardware or software failure is referred to as data corruption and this is one of the main problems which web hosting companies face since the larger a hard disk is and the more data is stored on it, the more likely it is for data to become corrupted. You'll find a couple of fail-safes, yet often the data gets damaged silently, so neither the file system, nor the administrators detect anything. Consequently, a bad file will be treated as a standard one and if the HDD is part of a RAID, that file will be copied on all other disk drives. In principle, this is for redundancy, but in reality the damage will get even worse. When a file gets corrupted, it will be partly or fully unreadable, therefore a text file will no longer be readable, an image file will show a random blend of colors if it opens at all and an archive shall be impossible to unpack, so you risk losing your content. Although the most frequently used server file systems include various checks, they quite often fail to discover some problem early enough or require a vast period of time in order to check all files and the 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 guaranteed by the ZFS file system that we employ on our cloud platform. The vast majority of hosting providers, including our firm, use multiple hard drives to keep content and since the drives work in a RAID, the exact same data is synchronized between the drives at all times. If a file on a drive becomes corrupted for reasons unknown, yet, it's more than likely that it will be duplicated on the other drives because other file systems do not feature special checks for that. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for every file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, which means that the bad copy shall be swapped with a good one from a different drive. As this happens in real time, there is no risk for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be protected against silent data corruption since all of our storage servers use the reliable ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, so as to verify the integrity of each and every file. When you upload content to your account, it will be saved on a couple of redundant drives being employed in a RAID i.e. the files will be the same across all drives. All of the copies of a specific file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates right away, and if it registers a mismatch, which will indicate that one of the copies is corrupted, it will replace that file with a healthy copy from one of the other drives. Even if there's 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 breakdown, prolonging the time needed for the server to go back online. ZFS is the only file system that can truly protect your content from silent data corruption.
