Data corruption is the damage of information because of various software or hardware problems. When a file is corrupted, it will no longer work correctly, so an app will not start or shall give errors, a text file will be partially or entirely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an administrator, that makes it a significant problem for hosting servers as failures are much more likely to occur on larger in size hard disk drives where considerable volumes of information are located. When a drive is part of a RAID and the information on it is replicated on other drives for redundancy, it's likely that the damaged file will be treated as a healthy one and will be duplicated on all drives, making the harm permanent. Lots of the file systems that operate on web servers today often cannot identify corrupted files instantly or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Shared Website Hosting

The integrity of the data which you upload to your new shared website hosting account will be guaranteed by the ZFS file system that we use on our cloud platform. Most hosting suppliers, including our firm, use multiple hard drives to keep content and considering that the drives work in a RAID, the same info is synchronized between the drives all of the time. In case a file on a drive gets corrupted for some reason, however, it's likely that it will be duplicated on the other drives since alternative file systems don't include special checks for that. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for every single file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, which means that the damaged copy shall be swapped with a good one from a different hard drive. As this happens right away, there is no risk for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you acquire one of our semi-dedicated hosting packages, you will not need to be concerned about silent file corruption since we use ZFS - a high level file system which checks all the files in real time. Every time you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between a couple of SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done in real time, so there will be no risk for any part of your content at any moment. In contrast, alternative file systems execute checks after a system failure, but since they don't use anything similar to the checksums which ZFS uses, they can't detect silently corrupted files, so a corrupted copy may be replicated on the remaining disks as well and you may lose important data. Since this isn't the case with ZFS, we are able to guarantee the integrity of every single file you upload no matter what.
