Data corruption is the unintentional change of a file or the loss of info which usually occurs during reading or writing. The reason could be hardware or software fail, and because of this, a file may become partially or fully corrupted, so it will no longer work properly as its bits will be scrambled or missing. An image file, for instance, will no longer display a real image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. In case such a problem occurs and it isn't found by the system or by an administrator, the data will get corrupted silently and when this happens on a disk drive which is a part of a RAID array where the info is synchronized between various drives, the corrupted file shall be reproduced on all other drives and the harm will be long term. Numerous widely used file systems either don't offer real-time checks or do not have good ones which can detect a problem before the damage is done, so silent data corruption is a common problem on hosting servers where large volumes of data are kept.
No Data Corruption & Data Integrity in Cloud Hosting
The integrity of the data which you upload to your new cloud hosting
account shall be guaranteed by the ZFS file system that we work with on our cloud platform. The vast majority of internet hosting suppliers, like our company, use multiple hard drives to keep content and considering that the drives work in a RAID, the exact same information is synchronized between the drives at all times. When a file on a drive is damaged for whatever reason, yet, it is likely that it will be copied on the other drives because other file systems don't offer special checks for that. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for every file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, and the bad copy shall be replaced with a good one from another hard disk. Since this happens in real time, there's no possibility for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any possibility of files getting corrupted silently due to the fact that the servers where your semi-dedicated hosting
account will be created employ a powerful file system known as ZFS. Its main advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. As we keep all content on a number of SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the remaining drives and the one it has saved. If there is a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and since this happens instantly, there's no chance that a damaged copy can remain on our web servers or that it can be copied to the other hard disks in the RAID. None of the other file systems use this kind of checks and furthermore, even during a file system check after a sudden power loss, none of them can detect silently corrupted files. In contrast, ZFS will not crash after an electrical power failure and the constant checksum monitoring makes a lenghty file system check unnecessary.
