Data corruption is the accidental change of a file or the losing of info which usually occurs during reading or writing. The reason can be hardware or software malfunction, and as a consequence, a file may become partially or completely corrupted, so it'll no longer work properly since its bits will be scrambled or lacking. An image file, for instance, will no longer show an accurate image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. In the event that this kind of an issue appears and it's not found by the system or by an administrator, the data will get corrupted silently and if this happens on a drive that's a part of a RAID array where the info is synchronized between different drives, the corrupted file will be duplicated on all of the other drives and the damage will be long term. Many widespread file systems either don't offer real-time checks or do not have good ones that can detect a problem before the damage is done, so silent data corruption is a rather common issue on internet hosting servers where huge amounts of information are stored.

No Data Corruption & Data Integrity in Cloud Website Hosting

We have tackled the problem of silent data corruption on all of our cloud website hosting servers by using the advanced Z file system, or ZFS. The latter is better than other file systems since it is the only one out there which checks all files in real time by using a checksum - a digital identifier that's unique for each and every file. When you upload content to your account, it'll be stored on several SSD drives and regularly synced between them for redundancy. ZFS constantly examines the checksum of all files and when any file is detected as corrupted, it's replaced quickly with a good copy from some other disk. As this happens in real time, there is no risk that a bad file may remain or may be copied on the remaining SSDs. ZFS requires lots of physical memory to perform the real-time checks and the advantage of our cloud hosting platform is that we employ multiple powerful servers working together. In case you host your Internet sites with us, your data will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you get one of our semi-dedicated hosting solutions, you won't have to be concerned about silent file corruption because we use ZFS - an advanced file system which monitors all the files in real time. Every time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between a couple of SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all the copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This happens right away, so there will be no danger for any part of your content at any moment. By comparison, other file systems carry out checks after a system malfunction, but since they don't use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a bad copy could be replicated on the other drives as well and you can lose important info. As this is not the case with ZFS, we're able to guarantee the integrity of each and every file you upload no matter what.
