Data corruption is the accidental transformation of a file or the loss of information which usually occurs during reading or writing. The reason can be hardware or software malfunction, and due to this fact, a file may become partially or completely corrupted, so it'll no longer work as it should since its bits shall be scrambled or missing. An image file, for instance, will no longer show a real image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. In case this kind of an issue occurs and it isn't noticed by the system or by an administrator, the data will become corrupted silently and when this happens on a drive which is part of a RAID array where the data is synchronized between various drives, the corrupted file will be copied on all the other drives and the harm will become long term. A number of commonly used file systems either do not offer real-time checks or do not have good ones which can detect an issue before the damage is done, so silent data corruption is a very common problem on web hosting servers where large amounts of information are kept.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data that you upload to your new shared hosting account will be guaranteed by the ZFS file system that we work with on our cloud platform. Most internet hosting suppliers, like our firm, use multiple hard disks to store content and considering that the drives work in a RAID, exactly the same data is synchronized between the drives at all times. When a file on a drive is corrupted for whatever reason, yet, it's likely that it will be copied on the other drives as alternative file systems do not offer special checks for that. Unlike them, ZFS applies a digital fingerprint, or a checksum, for every single file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, therefore the bad copy will be replaced with a good one from a different hard drive. Due to the fact that this happens instantly, there is no risk for any of your files to ever get corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
In case you buy one of our semi-dedicated hosting solutions, you will not have to be concerned about silent data corruption as we use ZFS - a high level file system that monitors all the files in real time. Each time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between a number of SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and if it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done in real time, so there will be no risk for any part of your content at any moment. In contrast, all the other file systems execute checks after a system failure, but since they don't use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a corrupted copy could be replicated on the remaining drives as well and you could lose crucial data. As this is not the case with ZFS, we can warrant the integrity of every single file you upload no matter what.
