Data corruption is the accidental change of a file or the loss of info that usually occurs during reading or writing. The reason could be hardware or software fail, and because of this, a file can become partially or entirely corrupted, so it will no longer function properly because its bits will be scrambled or lacking. An image file, for example, will no longer present an accurate image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etc. When such a problem occurs and it is not found by the system or by an admin, the data will be corrupted silently and in case this happens on a disk drive which is part of a RAID array where the info is synchronized between various different drives, the corrupted file will be replicated on all of the other drives and the harm will become long term. Many popular file systems either don't offer real-time checks or don't have good ones that can detect an issue before the damage is done, so silent data corruption is a common matter on web hosting servers where huge amounts of info are stored.

No Data Corruption & Data Integrity in Cloud Hosting

We've tackled the problem of silent data corruption on all of our cloud hosting servers by using the amazing Z file system, or ZFS. The latter is superior to other file systems because it is the only one on the market which checks all of the files in real time by employing a checksum - a digital identifier which is unique for each and every file. When you upload content to your account, it will be stored on several SSD drives and frequently synced between them for redundancy. ZFS regularly compares the checksum of all files and when any file is detected as damaged, it is replaced promptly with a good copy from some other disk. As this happens in real time, there's no risk that a damaged file may remain or may be copied on the remaining SSDs. ZFS requires plenty of physical memory in order to carry out the real-time checks and the advantage of our cloud website hosting platform is that we use multiple powerful servers working together. If you host your Internet sites with us, your information will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't need to deal with any kind of silent data corruption issues whatsoever should you get one of our semi-dedicated server packages due to the fact that the ZFS file system that we employ on our cloud hosting platform uses checksums in order to guarantee that all of your files are undamaged all of the time. A checksum is a unique digital fingerprint that is assigned to each and every file saved on a server. Because we store all content on multiple drives simultaneously, the same file uses the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives right away. In the event that it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy without delay, avoiding any chance of the bad copy to be synchronized on the rest of the drives. ZFS is the only file system you will find that uses checksums, which makes it much more reliable than other file systems that are not able to identify silent data corruption and duplicate bad files across hard drives.
