Data corruption is the damage of information caused by various software or hardware fails. After a file gets corrupted, it will no longer function as it should, so an application will not start or will give errors, a text file can be partially or fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an administrator, which makes it a serious problem for website hosting servers as fails are much more likely to happen on larger in size hard disks where substantial volumes of info are stored. When a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it's more than likely that the bad file will be treated as a healthy one and will be copied on all of the drives, making the harm permanent. A huge number of the file systems that run on web servers today often are not able to locate corrupted files right away or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Cloud Website Hosting

In case you host your websites in a cloud website hosting account from our firm, you will not need to worry about any of your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform works with the cutting-edge ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each and every file. Any info that you upload will be kept in a RAID i.e. simultaneously on numerous NVMe drives. A lot of file systems synchronize the files between the separate drives using this kind of a setup, but there is no real warranty that a file will not be corrupted. This can occur during the writing process on each drive and after that a bad copy may be copied on the other drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all of the drives in real time and in the event that a corrupted file is identified, it's replaced with a good copy with the correct checksum from some other drive. In this way, your info will stay undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any possibility of files getting corrupted silently since the servers where your semi-dedicated server account will be created work with a powerful file system named ZFS. Its advantage over alternative file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. As we keep all content on multiple NVMe drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has saved. In the event that there is a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and because this happens in real time, there is no chance that a corrupted copy can remain on our web servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems employ this kind of checks and in addition, even during a file system check right after an unexpected power loss, none of them will identify silently corrupted files. In comparison, ZFS won't crash after an electrical power failure and the regular checksum monitoring makes a time-consuming file system check unneeded.
