No Data Corruption & Data Integrity
Find what ‘No Data Corruption & Data Integrity’ suggests for the data inside your website hosting account.
Data corruption is the damage of information due to various hardware or software failures. Once a file gets corrupted, it will no longer function accurately, so an application will not start or shall give errors, a text file shall be partially or completely 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 significant problem for web hosting servers as problems are much more likely to occur on larger in size hard drives where vast volumes of info are located. When a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it's very likely that the damaged file will be treated as a regular one and it will be copied on all the drives, making the harm permanent. A huge number of the file systems that run on web servers these days often are unable to discover corrupted files right away or they need time-consuming system checks through which the server isn't operational.
No Data Corruption & Data Integrity in Shared Website Hosting
The integrity of the data that you upload to your new shared website hosting
account shall be guaranteed by the ZFS file system which we use on our cloud platform. The majority of internet hosting providers, like our company, use multiple HDDs to keep content and because the drives work in a RAID, the same information is synchronized between the drives all of the time. In case a file on a drive gets corrupted for some reason, however, it's very likely that it will be duplicated on the other drives because alternative file systems don't feature special checks for that. Unlike them, ZFS employs a digital fingerprint, or a checksum, for every file. If a file gets corrupted, its checksum won't match what ZFS has as a record for it, so the bad copy shall be swapped with a good one from another disk drive. As this happens right away, there is no risk for any of your files to ever get damaged.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
In case you acquire one of our semi-dedicated hosting
plans, you will not need to worry about silent file corruption because we use ZFS - a high level file system which keeps track of all the files in real time. Every 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 control. ZFS compares the checksum of all of the copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from another drive. This happens instantly, so there will be no risk for any part of your content at any time. By comparison, other file systems execute checks after a system failure, but since they do not use anything similar to the checksums that ZFS uses, they cannot detect silently corrupted files, so a corrupted copy could be replicated on the other drives as well and you can lose crucial data. As this isn't the case with ZFS, we warrant the integrity of every single file you upload no matter what.
