Data corruption is the unintended transformation of a file or the loss of information that usually occurs during reading or writing. The reason can be hardware or software malfunction, and for that reason, a file could become partially or fully corrupted, so it will no longer work as it should because its bits will be scrambled or lost. An image file, for instance, will no longer present an authentic image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etc. In case such a problem occurs and it isn't recognized by the system or by an administrator, the data will get corrupted silently and in case this happens on a drive which is part of a RAID array where the information is synchronized between various drives, the corrupted file will be copied on all of the other drives and the harm will become permanent. Many widespread file systems either do not offer real-time checks or do not have high quality ones that can detect an issue before the damage is done, so silent data corruption is a very common issue on hosting servers where huge amounts of info are stored.

No Data Corruption & Data Integrity in Hosting

In case you host your websites in a hosting account from our company, you won't need to worry about any of your data ever getting damaged. We can ensure that as our cloud hosting platform employs the amazing ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each file. All of the info that you upload will be stored in a RAID i.e. simultaneously on many SSDs. All of the file systems synchronize the files between the different drives with this type of a setup, but there's no real warranty that a file will not get corrupted. This could happen throughout the writing process on any 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 the drives in real time and in case a corrupted file is identified, it's replaced with a good copy with the correct checksum from some other drive. That way, your information will stay undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any chance of files getting corrupted silently since the servers where your semi-dedicated hosting account will be created work with a powerful file system called ZFS. Its main 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. As we keep all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the remaining drives and the one it has stored. If there's a mismatch, the corrupted copy is replaced with a good one from one of the other drives and since this happens instantly, there's no chance that a corrupted copy could remain on our servers or that it could be copied to the other drives in the RAID. None of the other file systems use such checks and in addition, even during a file system check after a sudden power loss, none of them will discover silently corrupted files. In comparison, ZFS won't crash after an electrical power failure and the continual checksum monitoring makes a lenghty file system check unnecessary.
