Data corruption is the damage of info caused by various software or hardware fails. The moment a file is corrupted, it will no longer function as it should, so an app will not start or shall give errors, a text file can be partially or completely unreadable, an archive file will be impossible to open and 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 very likely to occur on larger in size hard disks where considerable volumes of information are kept. If a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it's more than likely that the damaged file will be treated as a good one and it'll be copied on all of the drives, making the harm permanent. A huge number of the file systems that operate on web servers nowadays often are unable to find corrupted files instantly or they need time-consuming system checks through which the server is not functioning.

No Data Corruption & Data Integrity in Shared Web Hosting

The integrity of the data that you upload to your new shared web hosting account will be ensured by the ZFS file system which we make use of on our cloud platform. Most hosting suppliers, including our company, use multiple HDDs to store content and because the drives work in a RAID, exactly the same data is synchronized between the drives all of the time. When a file on a drive is damaged for whatever reason, however, it's more than likely that it will be reproduced on the other drives because alternative file systems do not have special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every single file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, and the bad copy will be substituted with a good one from another hard drive. Due to the fact that this happens instantly, there is no possibility for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you get one of our semi-dedicated server packages, you won't need to worry about silent file corruption as we use ZFS - a high level file system that checks 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. This file will be synced between several 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 in case it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done immediately, so there will be no risk for any part of your content at any time. In contrast, all the other file systems carry out checks after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy could be replicated on the other disks as well and you could lose important information. Because this isn't the case with ZFS, we are able to warrant the integrity of every single file you upload no matter what.
