Data corruption is the unintended change of a file or the loss of info which usually occurs during reading or writing. The reason could be hardware or software fail, and as a result, a file may become partially or entirely corrupted, so it'll no longer work as it should because its bits shall be scrambled or lost. An image file, for instance, will no longer present an accurate image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. If such a problem appears and it is not identified by the system or by an administrator, the data will get corrupted silently and if this happens on a drive which is a part of a RAID array where the information is synced between various drives, the corrupted file shall be duplicated on all other drives and the damage will become permanent. Numerous frequently used file systems either do not offer real-time checks or don't have good ones which will detect a problem before the damage is done, so silent data corruption is a very common problem on internet hosting servers where large amounts of data are stored.

No Data Corruption & Data Integrity in Website Hosting

In case you host your websites in a website hosting account with our company, you don't have to worry about your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform employs the advanced ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for every single file. All info that you upload will be kept in a RAID i.e. simultaneously on multiple SSDs. All file systems synchronize the files between the different drives using this kind of a setup, but there is no real guarantee that a file will not be corrupted. This may occur throughout the writing process on any drive and afterwards a bad copy can be copied on the rest of the drives. What is different on our platform is that ZFS examines the checksums of all files on all of the drives in real time and in the event that a corrupted file is identified, it is replaced with a good copy with the correct checksum from another drive. That way, your data will continue to be undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you acquire one of our semi-dedicated hosting packages, you will not need to worry about silent data corruption because we use ZFS - an advanced file system which checks all files in real time. Each time you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between several SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all 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 moment. In contrast, all the other file systems perform checks only after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they can't detect silently corrupted files, so a bad copy may be replicated on the remaining drives as well and you can lose important info. As this isn't the case with ZFS, we can warrant the integrity of each file you upload no matter what.
