Data corruption is the accidental modification of a file or the loss of info that usually occurs during reading or writing. The reason could be hardware or software fail, and for that reason, a file could become partially or completely corrupted, so it'll no longer function correctly since its bits will be scrambled or lost. An image file, for instance, will no longer present a real image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. In the event that this kind of an issue occurs and it isn't identified by the system or by an administrator, the data will be corrupted silently and in case this happens on a drive that's part of a RAID array where the information is synced between various different drives, the corrupted file will be duplicated on all other drives and the damage will become permanent. A large number of widespread file systems either do not have real-time checks or don't have high quality ones which will detect an issue before the damage is done, so silent data corruption is a common issue on internet hosting servers where huge volumes of info are stored.

No Data Corruption & Data Integrity in Cloud Hosting

The integrity of the data that 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 providers, like our firm, use multiple hard drives to store content and because the drives work in a RAID, the same information is synchronized between the drives all the time. If a file on a drive is damaged for reasons unknown, however, it is very likely that it will be reproduced on the other drives as alternative file systems don't feature special checks for this. Unlike them, ZFS uses a digital fingerprint, or a checksum, for each file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, therefore the damaged copy shall be replaced with a good one from another hard drive. Since this happens immediately, there is no possibility for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any probability of files getting damaged silently because the servers where your semi-dedicated hosting account will be created employ a powerful file system known as ZFS. Its main advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. As we keep all content on a number of SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has saved. If there is a mismatch, the bad copy is replaced with a good one from one of the other drives and considering that it 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 hard disks in the RAID. None of the other file systems include this type of checks and furthermore, even during a file system check right after a sudden power loss, none of them will discover silently corrupted files. In contrast, ZFS won't crash after a power failure and the constant checksum monitoring makes a lenghty file system check obsolete.
