Data corruption is the accidental transformation of a file or the loss of info that usually occurs during reading or writing. The reason may be hardware or software malfunction, and consequently, a file may become partially or completely corrupted, so it will no longer function as it should as its bits shall be scrambled or lost. An image file, for instance, will no longer present an authentic image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etc. When such an issue appears and it is not recognized by the system or by an admin, the data will get corrupted silently and when this happens on a disk drive which is part of a RAID array where the data is synchronized between various drives, the corrupted file shall be duplicated on all of the other drives and the harm will be permanent. Many widely used file systems either do not feature 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 substantial amounts of data are stored.

No Data Corruption & Data Integrity in Cloud Website Hosting

If you host your websites in a cloud website hosting account with our company, you don't need to worry about any of your data ever getting damaged. We can guarantee that because our cloud hosting platform employs the amazing ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each and every file. All of the data that you upload will be saved in a RAID i.e. simultaneously on many different SSD drives. All file systems synchronize the files between the separate drives with this type of a setup, but there's no real guarantee that a file won't be corrupted. This can happen at the time of the writing process on each drive and then a corrupted copy can be copied on all other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all the drives right away and when a corrupted file is found, it is substituted with a good copy with the correct checksum from some other drive. That way, your data will remain unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you acquire one of our semi-dedicated hosting packages, you will not need to worry about silent file corruption because we use ZFS - an advanced file system that checks all 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. The file will be synced between several SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and in case 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 time. In comparison, alternative file systems perform checks only after a system malfunction, but since they do not use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a bad copy could be replicated on the other drives as well and you can lose important info. As this isn't the case with ZFS, we're able to warrant the integrity of every single file you upload no matter what.
