Data corruption is the damage of data due to various hardware or software failures. When a file gets corrupted, it will no longer function accurately, so an app will not start or shall give errors, a text file could be partially or fully unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an administrator, that makes it a significant problem for web hosting servers as fails are much more likely to occur on larger hard drives where large volumes of info are kept. If a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it's very likely that the bad file will be treated as a healthy one and it'll be duplicated on all the drives, making the harm permanent. A huge number of the file systems which run on web servers nowadays often are unable to detect corrupted files in real time or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Hosting

The integrity of the data which you upload to your new hosting account shall be guaranteed by the ZFS file system that we use on our cloud platform. The majority of hosting providers, like our firm, use multiple hard drives to store content and because the drives work in a RAID, identical data is synchronized between the drives at all times. If a file on a drive becomes damaged for reasons unknown, yet, it is very likely that it will be duplicated on the other drives as other file systems do not have special checks for this. Unlike them, ZFS applies a digital fingerprint, or a checksum, for every single file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the bad copy will be replaced with a good one from a different disk drive. Because this happens immediately, there is no risk for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you acquire one of our semi-dedicated hosting solutions, you won't need to worry about silent file corruption as we use ZFS - an advanced file system which keeps track of all 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 couple of NVMe drives for redundancy, so if one drive fails, the other ones will take control. 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 a different drive. This is done instantly, so there will be no danger for any part of your content at any moment. In comparison, all the other file systems carry out checks after a system breakdown, but since they do not use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a bad copy could be replicated on the remaining drives as well and you could lose crucial information. Since this isn't the case with ZFS, we are able to guarantee the integrity of each file you upload no matter what.
