Data corruption is the unintentional modification of a file or the losing of info that usually occurs during reading or writing. The reason can be hardware or software malfunction, and for that reason, a file may become partially or completely corrupted, so it'll no longer work properly as its bits shall be scrambled or lacking. An image file, for instance, will no longer display an accurate image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. If such a problem occurs and it isn't recognized by the system or by an admin, the data will be corrupted silently and in case this happens on a drive that's a 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 damage will become long term. Many frequently used file systems either do not feature real-time checks or do not have high quality ones which will detect an issue before the damage is done, so silent data corruption is a rather common issue on web hosting servers where large amounts of information are kept.

No Data Corruption & Data Integrity in Shared Hosting

If you host your websites in a shared hosting account with our company, you do not need to worry about your data ever getting damaged. We can ensure that since our cloud hosting platform uses the outstanding ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for every single file. Any kind of data that you upload will be saved in a RAID i.e. simultaneously on many NVMes. All file systems synchronize the files between the different drives using this kind of a setup, but there's no real warranty that a file will not be corrupted. This could occur at the time of the writing process on each drive and afterwards a bad copy may be copied on the other drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all of the drives immediately and when a corrupted file is found, it's replaced with a good copy with the correct checksum from another drive. In this way, your data will remain intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you obtain one of our semi-dedicated hosting solutions, you will not need to be concerned about silent data corruption since we use ZFS - a high level file system that keeps track of all the files in real time. Whenever you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between multiple NVMe drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from a different drive. This happens in real time, so there will be no danger for any part of your content at any moment. In comparison, all the other file systems carry out checks after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a bad copy may be replicated on the rest of the drives as well and you can lose crucial data. Since this isn't the case with ZFS, we warrant the integrity of each file you upload no matter what.
