Data corruption is the unintentional modification of a file or the loss of information which usually occurs during reading or writing. The reason could be hardware or software malfunction, and consequently, a file may become partially or fully corrupted, so it'll no longer work as it should since its bits shall be scrambled or lost. An image file, for instance, will no longer show an actual image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. When this kind of a problem appears and it is not recognized by the system or by an admin, the data will be corrupted silently and if this happens on a drive which is part of a RAID array where the information is synchronized between various different drives, the corrupted file shall be reproduced on all of the other drives and the damage will become long term. Many widely used file systems either don't offer real-time checks or do not have good ones that will detect a problem before the damage is done, so silent data corruption is a common problem on hosting servers where large amounts of data are stored.

No Data Corruption & Data Integrity in Hosting

In case you host your websites in a hosting account from our firm, you don't need to worry about any of your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform employs the cutting-edge ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each and every file. All data that you upload will be stored in a RAID i.e. simultaneously on numerous NVMe drives. All the file systems synchronize the files between the different drives using this type of a setup, but there is no real warranty that a file won't get corrupted. This can occur at the time of the writing process on each drive and after that a bad copy may be copied on the rest of the drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all drives in real time and in case a corrupted file is identified, it is swapped with a good copy with the correct checksum from another drive. In this way, your information will remain intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you obtain one of our semi-dedicated server solutions, you will not have to be concerned about silent data corruption as we use ZFS - a high level file system which checks all of 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. That file will be synchronized between a number of NVMe drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and if it detects a damaged 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 time. By comparison, all the other file systems perform checks only after a system breakdown, but since they do not use anything similar to the checksums that ZFS uses, they cannot detect silently corrupted files, so a corrupted copy can be replicated on the rest of the drives as well and you can lose critical data. As this isn't the case with ZFS, we guarantee the integrity of every single file you upload no matter what.
