Data corruption is the damage of information because of various hardware or software failures. Once a file is corrupted, it will no longer function accurately, so an app will not start or will give errors, a text file shall be partially or entirely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an administrator, which makes it a significant problem for hosting servers as failures are more likely to occur on larger hard disks where vast volumes of information are stored. When a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it's more than likely that the bad file will be treated as an ordinary one and it'll be duplicated on all the drives, making the damage permanent. Lots of the file systems which run on web servers today often are not able to detect corrupted files instantly or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Cloud Web Hosting

The integrity of the data that you upload to your new cloud web hosting account will be guaranteed by the ZFS file system that we make use of on our cloud platform. Most hosting providers, including our company, use multiple hard disks to keep content and since the drives work in a RAID, the exact same info is synchronized between the drives all the time. When a file on a drive gets corrupted for whatever reason, yet, it is likely that it will be duplicated on the other drives as other file systems do not feature special checks for that. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for every single file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, which means that the bad copy will be replaced with a good one from another disk drive. Due to the fact that this happens in real time, there's no possibility for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any probability of files getting corrupted silently since the servers where your semi-dedicated hosting account will be created employ a powerful file system known as ZFS. Its key advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that is checked in real time. As we keep all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has stored. If there's a mismatch, the damaged copy is replaced with a good one from one of the other drives and since this happens right away, there is no chance that a corrupted copy could remain on our hosting 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 what's more, even during a file system check following a sudden electrical power failure, none of them will detect silently corrupted files. In contrast, ZFS won't crash after an electrical power failure and the continual checksum monitoring makes a time-consuming file system check obsolete.
