Data corruption is the damage of data because of various software or hardware failures. When a file is damaged, it will no longer work correctly, so an application will not start or shall give errors, a text file could be partially or fully unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an administrator, which makes it a serious problem for web hosting servers as fails are more likely to happen on larger in size hard disk drives where considerable volumes of information are located. In case a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it is more than likely that the damaged file will be treated as a good one and will be duplicated on all the drives, making the harm permanent. Lots of the file systems which operate on web servers nowadays often are unable to locate corrupted files right away or they need time-consuming system checks during which the server is not functioning.

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 that we use on our cloud platform. The majority of internet hosting service providers, including our firm, use multiple hard disk drives to store content and considering that the drives work in a RAID, exactly the same info is synchronized between the drives all the time. In case a file on a drive gets corrupted for some reason, yet, it is more than likely that it will be duplicated on the other drives since other file systems do not include special checks for that. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for each and every file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, and the bad copy shall be replaced with a good one from a different hard disk. Because this happens instantly, there's no risk for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any chance of files getting corrupted silently because the servers where your semi-dedicated hosting account will be created work with a powerful file system named ZFS. Its advantage over various other file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. Since we save all content on multiple NVMe drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has stored. If there is a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and since this happens right away, there is no chance that a damaged copy could remain on our web servers or that it can be copied to the other drives in the RAID. None of the other file systems include such checks and in addition, even during a file system check following an unexpected blackout, none of them can identify silently corrupted files. In contrast, ZFS won't crash after a blackout and the constant checksum monitoring makes a time-consuming file system check obsolete.
