Data corruption is the damage of information due to various hardware or software failures. After a file gets corrupted, it will no longer work correctly, so an application will not start or shall give errors, a text file will be partially or fully unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an admin, that makes it a serious problem for website hosting servers as failures are much more likely to occur on larger in size hard drives where significant volumes of info are kept. When a drive is part of a RAID and the data on it is copied on other drives for redundancy, it's very likely that the damaged file will be treated as an ordinary one and it'll be copied on all the drives, making the damage permanent. A lot of the file systems which operate on web servers nowadays often cannot recognize corrupted files immediately or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data that you upload to your new shared hosting account will be guaranteed by the ZFS file system that we make use of on our cloud platform. Most of the internet hosting service providers, including our firm, use multiple HDDs to keep content and because the drives work in a RAID, identical data is synchronized between the drives all the time. When a file on a drive becomes corrupted for whatever reason, yet, it's likely that it will be copied on the other drives as other file systems don't offer special checks for that. Unlike them, ZFS employs a digital fingerprint, or a checksum, for each and every file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, so the damaged copy will be substituted with a good one from another drive. As this happens in real time, there is no risk for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you buy one of our semi-dedicated server packages, you won't have to worry about silent data corruption as we use ZFS - a high level file system that monitors all of the files in real time. Each time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between multiple 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 if it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done in real time, so there will be no risk for any part of your content at any time. By comparison, alternative 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 won't detect silently corrupted files, so a bad copy could be replicated on the remaining disks as well and you may lose important information. As this isn't the case with ZFS, we can warrant the integrity of each and every file you upload no matter what.
