Data corruption is the accidental modification of a file or the loss of info which usually occurs during reading or writing. The reason can be hardware or software fail, and for that reason, a file may become partially or fully corrupted, so it'll no longer work properly because its bits shall be scrambled or lost. An image file, for instance, will no longer display a true image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. If such a problem occurs and it is not noticed by the system or by an admin, the data will become corrupted silently and when this happens on a drive that is a part of a RAID array where the information is synchronized between different drives, the corrupted file will be duplicated on all the other drives and the damage will become permanent. Many widely used file systems either don't have real-time checks or do not have high quality ones that can detect an issue before the damage is done, so silent data corruption is a rather common problem on internet hosting servers where huge amounts of info are stored.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your sites in a cloud hosting account from our company, you do not have to worry about any of your data ever getting corrupted. We can guarantee that because our cloud hosting platform uses the amazing ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for every single file. All of the info that you upload will be stored in a RAID i.e. simultaneously on numerous SSD drives. All 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 be corrupted. This can happen throughout the writing process on any drive and afterwards a corrupted copy can be copied on all other drives. What makes the difference on our platform is the fact that ZFS analyzes the checksums of all files on all the drives instantly and in the event that a corrupted file is discovered, it's substituted with a good copy with the correct checksum from another drive. By doing this, your information will stay intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you get one of our semi-dedicated hosting packages, you will not need to be concerned about silent file corruption as we use ZFS - a high level file system which monitors all files in real time. Every time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between multiple SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all the copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from a different drive. This happens in real time, so there will be no risk for any part of your content at any moment. In contrast, all of the other file systems carry out checks only after a system malfunction, but since they do not use anything similar to the checksums that ZFS uses, they cannot detect silently corrupted files, so a bad copy could be replicated on the remaining disks as well and you can lose precious info. As this is not the case with ZFS, we can warrant the integrity of every single file you upload no matter what.
