Data corruption is the accidental modification of a file or the loss of information which usually occurs during reading or writing. The reason may be hardware or software fail, and consequently, a file may become partially or completely corrupted, so it will no longer work as it should since its bits shall be scrambled or lacking. An image file, for example, will no longer show a true image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etc. In case such an issue appears and it isn't noticed 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 info is synchronized between various drives, the corrupted file will be reproduced on all of the other drives and the harm will become long term. Many widely used file systems either do not offer real-time checks or do not have good ones that can detect an issue before the damage is done, so silent data corruption is a rather common problem on hosting servers where huge amounts of information are kept.

No Data Corruption & Data Integrity in Web Hosting

In case you host your Internet sites in a web hosting account with our company, you will not need to worry about your data ever getting damaged. We can ensure that because 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 file. All the data that you upload will be stored in a RAID i.e. simultaneously on many different SSDs. All of the file systems synchronize the files between the separate drives with this type of a setup, but there's no real warranty that a file will not be corrupted. This can happen throughout the writing process on any drive and after that a damaged copy can be copied on the other drives. What is different on our platform is that ZFS compares the checksums of all files on all the drives right away and in case a corrupted file is found, it is swapped with a good copy with the correct checksum from some other drive. By doing this, your information will remain 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 won't need to worry about silent file corruption because we use ZFS - an advanced file system which checks all of the files in real time. Whenever you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between several SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all of the copies on the different drives and in case it detects a corrupted copy, it replaces it with a healthy one from another drive. This happens immediately, so there will be no threat for any part of your content at any time. In comparison, 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 can't detect silently corrupted files, so a bad copy could be replicated on the remaining disks as well and you could lose important info. Because this isn't the case with ZFS, we guarantee the integrity of each file you upload no matter what.
