Data corruption is the damage of information caused by various hardware or software problems. When a file gets corrupted, it will no longer function correctly, so an app will not start or shall give errors, a text file could 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 harmed without any acknowledgement by the system or an administrator, that makes it a significant problem for web hosting servers as fails are very likely to happen on bigger hard disks where large volumes of info are located. If a drive is a part of a RAID and the information on it is replicated on other drives for redundancy, it is likely that the bad file will be treated as a standard one and it will be duplicated on all drives, making the damage permanent. Lots of the file systems that operate on web servers these days often are unable to locate corrupted files immediately or they need time-consuming system checks through which the server isn't operational.

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 ensured by the ZFS file system which we use on our cloud platform. The vast majority of web hosting service providers, like our firm, use multiple HDDs to store content and because the drives work in a RAID, identical information is synchronized between the drives at all times. When a file on a drive is damaged for some reason, however, it is more than likely that it will be duplicated on the other drives because other file systems do not include special checks for this. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for each and every file. In case a file gets damaged, its checksum will not match what ZFS has as a record for it, therefore the bad copy shall be swapped with a good one from another hard disk. Due to the fact that this happens instantly, there's no risk 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 solutions, you won't need to worry about silent file corruption since we use ZFS - a high level file system which keeps track of all files in real time. Every time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between a couple 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 when it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done in real time, so there will be no threat for any part of your content at any moment. In comparison, all of the other file systems perform checks after a system malfunction, but since they do not use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a corrupted copy can be replicated on the remaining drives as well and you can lose critical info. Since this is not the case with ZFS, we're able to guarantee the integrity of each and every file you upload no matter what.
