Data corruption is the damage of info due to various software or hardware fails. When a file gets damaged, it will no longer function as it should, so an application will not start or will give errors, a text file will 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 administrator, that makes it a significant problem for website hosting servers as fails are very likely to happen on bigger hard disk drives where considerable volumes of info are located. If a drive is part of a RAID and the information on it is replicated on other drives for redundancy, it is more than likely that the bad file will be treated as a regular one and it'll be copied on all drives, making the damage permanent. Lots of the file systems which run on web servers these days often are not able to recognize corrupted files instantly or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Web Hosting

If you host your sites in a web hosting account from our firm, you won't need to worry about your data ever getting corrupted. We can ensure that since our cloud hosting platform uses the advanced ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each and every file. Any kind of data that you upload will be stored in a RAID i.e. simultaneously on multiple SSDs. All of the file systems synchronize the files between the different drives with this kind of a setup, but there's no real guarantee that a file won't be corrupted. This may occur at the time of the writing process on any drive and afterwards a bad copy may be copied on the other drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all drives immediately and in case a corrupted file is located, it is substituted with a good copy with the correct checksum from some other drive. By doing this, your data will remain undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not encounter any silent data corruption issues should you buy one of our semi-dedicated hosting solutions due to the fact that the ZFS file system that we use on our cloud hosting platform uses checksums in order to ensure that all the files are intact all of the time. A checksum is a unique digital fingerprint which is allotted to each and every file kept on a server. As we store all content on multiple drives at the same time, the same file uses the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. If 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 bad copy to be synchronized on the remaining drives. ZFS is the sole file system you will find that uses checksums, which makes it much more reliable than other file systems that are unable to identify silent data corruption and copy bad files across drives.
