Data corruption is the damage of info due to various software or hardware fails. When a file gets damaged, it will no longer work accurately, so an app will not start or shall give errors, a text file shall be partially or entirely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an admin, that makes it a serious problem for website hosting servers as failures are very likely to occur on bigger hard disks where vast volumes of information are located. In case a drive is a part of a RAID and the data on it is duplicated on other drives for redundancy, it is very likely that the damaged file will be treated as a regular one and will be duplicated on all of the drives, making the damage permanent. A huge number of the file systems that operate on web servers these days often cannot identify corrupted files immediately or they need time-consuming system checks through which the server is not operational.

No Data Corruption & Data Integrity in Cloud Website Hosting

In case you host your Internet sites in a cloud website hosting account from our company, you won't have to worry about any of your data ever getting damaged. We can ensure that as our cloud hosting platform employs the state-of-the-art ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each and every file. Any kind of info that you upload will be stored in a RAID i.e. simultaneously on a number of SSD drives. All of the file systems synchronize the files between the separate drives with this kind of a setup, but there is no real guarantee that a file will not be corrupted. This can happen throughout the writing process on any drive and then a bad copy can be copied on the rest of the drives. What is different on our platform is that ZFS examines the checksums of all files on all drives live and if a corrupted file is located, it's substituted with a good copy with the correct checksum from another drive. By doing this, your data will remain intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you go for one of our semi-dedicated server solutions, you won't need to be concerned about silent data corruption because we use ZFS - an advanced file system which keeps track of 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. 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 another drive. This is done right away, so there will be no risk for any part of your content at any time. In contrast, alternative file systems carry out checks only after a system malfunction, but since they don't use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a corrupted copy can be replicated on the other drives as well and you can lose important information. As this isn't the case with ZFS, we're able to guarantee the integrity of every single file you upload no matter what.
