Data corruption is the damage of information caused by various software or hardware failures. The moment a file gets damaged, it will no longer work accurately, so an app will not start or shall give errors, a text file shall be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an administrator, that makes it a significant problem for web hosting servers as fails are much more likely to happen on larger in size hard drives where large volumes of information are stored. If a drive is part of a RAID and the information on it is replicated on other drives for redundancy, it's more than likely that the bad file will be treated as a regular one and will be copied on all of the drives, making the damage permanent. A huge number of the file systems that operate on web servers today often are unable to recognize corrupted files immediately or they need time-consuming system checks through which the server isn't functioning.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data which you upload to your new shared hosting account shall be guaranteed by the ZFS file system that we use on our cloud platform. The majority of internet hosting service providers, including our firm, use multiple hard disks to keep content and considering that the drives work in a RAID, exactly the same information is synchronized between the drives all of the time. In case a file on a drive is corrupted for some reason, yet, it's very likely that it will be copied on the other drives since alternative file systems don't have special checks for this. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for every file. In the event that a file gets damaged, its checksum will not match what ZFS has as a record for it, and the bad copy shall be substituted with a good one from another drive. Due to the fact that this happens instantly, there's no possibility for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any probability of files getting damaged silently due to the fact that the servers where your semi-dedicated server account will be created take advantage of a powerful file system known as ZFS. Its advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. Since we save all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. When there's a mismatch, the corrupted copy is replaced with a good one from one of the other drives and considering that this happens in real time, there's no chance that a damaged copy can remain on our hosting servers or that it can be duplicated to the other drives in the RAID. None of the other file systems include this type of checks and what is more, even during a file system check right after an unexpected power failure, none of them will identify silently corrupted files. In comparison, ZFS will not crash after an electrical power failure and the continual checksum monitoring makes a time-consuming file system check unnecessary.
