Data corruption is the damage of info because of various software or hardware problems. When a file gets corrupted, it will no longer work as it should, so an application will not start or shall give errors, a text file could 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 damaged without any identification by the system or an administrator, that makes it a significant problem for web hosting servers as problems are much more likely to occur on bigger hard drives where large volumes of info are placed. If a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it's very likely that the damaged file will be treated as a good one and it will be copied on all of the drives, making the damage permanent. Lots of the file systems which operate on web servers nowadays often are not able to detect corrupted files right away or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Shared Web Hosting

If you host your sites in a shared web hosting account with our company, you will not need to worry about any of your data ever getting damaged. We can guarantee that since our cloud hosting platform works with the outstanding ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each and every file. All of the data that you upload will be saved in a RAID i.e. simultaneously on numerous SSDs. All file systems synchronize the files between the separate drives using this kind of a setup, but there's no real guarantee that a file will not get corrupted. This may occur during the writing process on any drive and then a corrupted copy may 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 of the drives instantly and in the event that a corrupted file is identified, it's swapped with a good copy with the correct checksum from another drive. In this way, your info will continue to be intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you obtain one of our semi-dedicated hosting packages, you won't have to worry about silent file corruption because we use ZFS - an advanced file system which keeps track of all 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. The file will be synchronized between a number of SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all 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 instantly, so there will be no threat for any part of your content at any time. In contrast, alternative file systems perform checks only after a system breakdown, but since they do not use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a corrupted copy can be replicated on the other drives as well and you may lose crucial information. Because this isn't the case with ZFS, we guarantee the integrity of each and every file you upload no matter what.
