Data corruption is the damage of information because of various software or hardware failures. When a file is corrupted, it will no longer function correctly, so an app will not start or shall give errors, a text file can be partially or fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an admin, which makes it a serious problem for hosting servers as fails are very likely to occur on larger in size hard drives where considerable volumes of information are located. If a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it is likely that the damaged file will be treated as an ordinary one and will be copied on all of the drives, making the damage permanent. Lots of the file systems which run on web servers today often are not able to locate corrupted files in real time or they need time-consuming system checks through which the server isn't operational.

No Data Corruption & Data Integrity in Cloud Website Hosting

If you host your websites in a cloud website hosting account with our firm, you don't need to worry about any of your data ever getting corrupted. We can ensure that since our cloud hosting platform employs the state-of-the-art ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for every single file. Any kind of data that you upload will be stored in a RAID i.e. simultaneously on multiple SSD drives. All of the file systems synchronize the files between the different drives with this type of a setup, but there is no real warranty that a file won't get corrupted. This could occur throughout 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 the fact that ZFS compares the checksums of all files on all of the drives in real time and in case a corrupted file is identified, it is swapped with a good copy with the correct checksum from another drive. In this way, your info will remain undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you purchase one of our semi-dedicated hosting plans, you won't have to be concerned about silent data corruption as we use ZFS - a high level file system which checks all of the 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 in case it detects a corrupted copy, it replaces it with a healthy one from another drive. This happens instantly, so there will be no threat for any part of your content at any time. In comparison, alternative file systems execute checks after a system failure, but since they do not use anything similar to the checksums which ZFS uses, they won't detect silently corrupted files, so a corrupted copy may be replicated on the other disks as well and you could lose critical data. Since this is not the case with ZFS, we guarantee the integrity of each and every file you upload no matter what.
