Data corruption is the accidental change of a file or the losing of info 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 properly because its bits will be scrambled or lost. An image file, for instance, will no longer display an accurate image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. In the event that this kind of an issue occurs and it is not recognized by the system or by an administrator, the data will get corrupted silently and if this happens on a disk drive that's a part of a RAID array where the information is synchronized between various drives, the corrupted file will be replicated on all the other drives and the damage will be long term. A large number of widespread file systems either don't have real-time checks or do not have good ones that can detect an issue before the damage is done, so silent data corruption is a very common issue on hosting servers where substantial volumes of information are kept.
No Data Corruption & Data Integrity in Hosting
The integrity of the data that you upload to your new hosting
account shall be ensured by the ZFS file system that we make use of on our cloud platform. Most of the internet hosting suppliers, including our company, use multiple hard disk drives to store content and considering that the drives work in a RAID, exactly the same data is synchronized between the drives all of the time. In case a file on a drive gets corrupted for whatever reason, yet, it is likely that it will be copied on the other drives since alternative file systems do not offer special checks for that. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for each file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, and the bad copy shall be swapped with a good one from a different hard disk drive. Since this happens immediately, there's no possibility for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any risk of files getting damaged silently because the servers where your semi-dedicated server
account will be created employ a powerful file system named ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. Since we save all content on multiple SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. In case there is a mismatch, the bad copy is replaced with a good one from one of the other drives and considering that it happens right away, there's no chance that a damaged 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 this kind of checks and in addition, even during a file system check right after an unexpected blackout, none of them will find silently corrupted files. In contrast, ZFS doesn't crash after a power failure and the continual checksum monitoring makes a time-consuming file system check obsolete.
