Data corruption is the damage of data caused by various software or hardware problems. Once a file gets corrupted, it will no longer function correctly, so an application will not start or shall give errors, a text file can be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an admin, that makes it a serious problem for website hosting servers as failures are much more likely to occur on larger in size hard drives where significant volumes of information are located. When a drive is part of a RAID and the information on it is duplicated on other drives for redundancy, it is likely that the damaged file will be treated as an undamaged one and it'll be copied on all the drives, making the harm permanent. A huge number of the file systems that operate on web servers these days often are not able to detect corrupted files in real time or they need time-consuming system checks during which the server isn't operational.

No Data Corruption & Data Integrity in Hosting

If you host your Internet sites in a hosting account with our company, you don't need to worry about your data ever getting corrupted. We can ensure that since our cloud hosting platform works with the advanced ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each and every file. Any data that you upload will be kept in a RAID i.e. simultaneously on a number of NVMes. A lot of file systems synchronize the files between the different drives using this type of a setup, but there's no real warranty that a file will not be corrupted. This can occur during the writing process on each drive and then a damaged copy can be copied on all other drives. What makes the difference on our platform is the fact that ZFS analyzes the checksums of all files on all drives in real time and in the event that a corrupted file is located, it is swapped with a good copy with the correct checksum from another drive. By doing this, your information will remain unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any risk of files getting corrupted silently due to the fact that the servers where your semi-dedicated hosting account will be created use a powerful file system known as ZFS. Its main advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint which is checked in real time. As we save all content on numerous NVMe drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has stored. When there is a mismatch, the bad copy is replaced with a healthy one from one of the other drives and considering that it happens in real time, there is no chance that a corrupted copy can remain on our web servers or that it can be duplicated to the other hard drives in the RAID. None of the other file systems employ this kind of checks and furthermore, even during a file system check after a sudden power failure, 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 obsolete.
