Data corruption is the accidental modification of a file or the losing of information that often occurs during reading or writing. The reason could be hardware or software fail, and consequently, a file can become partially or entirely corrupted, so it'll no longer work correctly since its bits shall be scrambled or lacking. An image file, for example, will no longer display an actual image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. In case such a problem occurs and it isn't noticed by the system or by an administrator, the data will become corrupted silently and in case this happens on a drive that is a part of a RAID array where the information is synced between various different drives, the corrupted file shall be replicated on all the other drives and the damage will become long term. Many frequently used file systems either don't feature real-time checks or don't have high quality ones which will detect a problem before the damage is done, so silent data corruption is a common issue on hosting servers where large volumes of data are kept.

No Data Corruption & Data Integrity in Hosting

If you host your websites in a hosting account with our firm, you won't need to worry about your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform uses the state-of-the-art ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for every single file. Any information that you upload will be stored in a RAID i.e. simultaneously on multiple SSDs. All file systems synchronize the files between the different drives with such a setup, but there is no real warranty that a file won't be corrupted. This may happen throughout the writing process on each drive and after that a corrupted copy can be copied on the rest of the drives. What is different on our platform is that ZFS compares the checksums of all files on all of the drives live and in the event that a corrupted file is located, it is substituted with a good copy with the correct checksum from some other drive. In this way, your info will continue to be undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any possibility of files getting corrupted silently because the servers where your semi-dedicated hosting account will be created use a powerful file system named ZFS. Its key advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that is checked in real time. Since we store all content on a number of SSD drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has saved. In the event that there's a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and considering that it happens right away, there is no chance that a corrupted copy could remain on our website hosting servers or that it can be copied to the other drives in the RAID. None of the other file systems work with this kind of checks and what's more, even during a file system check following an unexpected electrical power failure, none of them can find silently corrupted files. In contrast, ZFS doesn't crash after a power loss and the continual checksum monitoring makes a lenghty file system check unnecessary.
