Data corruption is the damage of data due to various software or hardware problems. After a file is corrupted, it will no longer work as it should, so an application will not start or shall give errors, a text file shall be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an administrator, which makes it a serious problem for hosting servers as fails are much more likely to happen on larger in size hard drives where considerable volumes of information are located. When a drive is part of a RAID and the information 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 will be duplicated on all drives, making the harm permanent. A huge number of the file systems that operate on web servers today often are unable to locate 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 that you upload to your new shared website hosting account shall be guaranteed by the ZFS file system which we take advantage of on our cloud platform. Most of the web hosting suppliers, like our firm, use multiple HDDs to keep content and since the drives work in a RAID, identical information is synchronized between the drives all the time. If a file on a drive becomes damaged for whatever reason, however, it is more than likely that it will be reproduced on the other drives as alternative file systems don't feature special checks for this. Unlike them, ZFS employs a digital fingerprint, or a checksum, for each and every file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, therefore the damaged copy shall be replaced with a good one from another hard disk. Due to the fact that 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 solutions, you will not need to worry about silent file corruption as we use ZFS - an advanced file system which checks all the files in real time. Whenever you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between multiple SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all of the copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from another drive. This happens in real time, so there will be no danger for any part of your content at any time. By comparison, all of the other file systems carry out checks only after a system malfunction, but since they do not use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a bad copy may be replicated on the other disks as well and you can lose important info. As this is not the case with ZFS, we're able to guarantee the integrity of every single file you upload no matter what.
