Data corruption is the damage of data due to various software or hardware fails. Once a file is corrupted, it will no longer work correctly, so an app will not start or shall give errors, a text file could be partially or entirely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an administrator, that makes it a serious problem for web hosting servers as problems are very likely to happen on larger hard disks where vast volumes of information are located. When a drive is a part of a RAID and the data on it is copied 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 drives, making the damage permanent. A huge number of the file systems which run on web servers these days often are unable to discover corrupted files immediately or they need time-consuming system checks through which the server isn't functioning.
No Data Corruption & Data Integrity in Cloud Web Hosting
The integrity of the data which you upload to your new cloud web hosting
account shall be guaranteed by the ZFS file system that we work with on our cloud platform. Most of the internet hosting service providers, like our firm, use multiple hard disk drives to store content and because the drives work in a RAID, the same information is synchronized between the drives all of the time. If a file on a drive gets corrupted for reasons unknown, however, it's very likely that it will be duplicated on the other drives since other file systems do not include special checks for this. Unlike them, ZFS uses a digital fingerprint, or a checksum, for every single file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the bad copy will be swapped with a good one from another drive. Because this happens immediately, there's no risk for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
In case you buy one of our semi-dedicated hosting
solutions, you will not need to worry about silent data corruption as we use ZFS - an advanced file system that keeps track of all the files in real time. Each time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between a number 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 if it detects a damaged copy, it replaces it with a healthy one from another drive. This is done instantly, so there will be no threat for any part of your content at any time. In contrast, other file systems carry out checks only after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy can be replicated on the rest of the disks as well and you may lose important data. As this is not the case with ZFS, we can warrant the integrity of every single file you upload no matter what.
