Data corruption is the damage of data caused by various hardware or software failures. When a file is corrupted, it will no longer work accurately, so an application will not start or shall give errors, a text file can be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an admin, which makes it a significant problem for hosting servers as failures are much more likely to happen on bigger hard disk drives where considerable volumes of info are stored. If a drive is a part of a RAID and the information on it is replicated on other drives for redundancy, it's more than likely that the damaged file will be treated as a healthy one and it'll be copied on all the drives, making the harm permanent. Lots of the file systems which operate on web servers today often are not able to recognize 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 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 that we employ on our cloud platform. Most hosting suppliers, like our company, use multiple HDDs to store content and considering that the drives work in a RAID, exactly the same information is synchronized between the drives at all times. In case a file on a drive gets corrupted for some reason, yet, it is likely that it will be duplicated on the other drives because alternative file systems don't feature special checks for that. Unlike them, ZFS uses a digital fingerprint, or a checksum, for each file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, so the damaged copy will be replaced with a good one from a different drive. As this happens right away, there's no risk for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not have to deal with any kind of silent data corruption issues if you buy one of our semi-dedicated hosting plans because the ZFS file system that we work with on our cloud hosting platform uses checksums to guarantee that all of the files are intact all of the time. A checksum is a unique digital fingerprint which is assigned to each and every file stored on a server. As we store all content on multiple drives simultaneously, the same file uses the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives right away. In case it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy without delay, avoiding any possibility of the corrupted copy to be synchronized on the other drives. ZFS is the only file system you will find that uses checksums, which makes it much more dependable than other file systems which cannot identify silent data corruption and copy bad files across drives.
