Data corruption is the unintended modification of a file or the losing of information which usually occurs during reading or writing. The reason could be hardware or software failure, and consequently, a file can become partially or completely corrupted, so it will no longer function as it should since its bits shall be scrambled or lacking. An image file, for instance, will no longer show an accurate image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etc. In case this kind of a problem appears and it isn't noticed by the system or by an admin, the data will get corrupted silently and in case this happens on a disk drive that's part of a RAID array where the information is synced between various different drives, the corrupted file will be reproduced on all other drives and the damage will become permanent. A large number of widespread file systems either do not offer real-time checks or don't have high quality ones which can detect a problem before the damage is done, so silent data corruption is a common issue on internet hosting servers where huge volumes of info are stored.

No Data Corruption & Data Integrity in Web Hosting

If you host your sites in a web hosting account from our company, you do not have 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 leading-edge ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each and every file. All of the information that you upload will be kept in a RAID i.e. simultaneously on many different SSD drives. All the file systems synchronize the files between the different drives with this kind of a setup, but there is no real warranty that a file won't be corrupted. This could happen during the writing process on each drive and then a bad copy can be copied on the rest of the drives. What is different on our platform is the fact that ZFS examines the checksums of all files on all the drives immediately and when a corrupted file is discovered, it is swapped with a good copy with the correct checksum from another drive. In this way, your data will remain unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you purchase one of our semi-dedicated server plans, you will not need to worry about silent file corruption because we use ZFS - an advanced file system that checks all of the files in real time. Whenever 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 synced between multiple SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all 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 is done in real time, so there will be no threat for any part of your content at any time. In contrast, all of the other file systems carry out checks only after a system malfunction, but since they don't use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a bad copy can be replicated on the rest of the disks as well and you may lose crucial information. As this isn't the case with ZFS, we can guarantee the integrity of every single file you upload no matter what.
