Data corruption is the unintended modification of a file or the loss of information which usually occurs during reading or writing. The reason could be hardware or software fail, and due to this fact, a file could become partially or completely corrupted, so it'll no longer work correctly since its bits will be scrambled or lacking. An image file, for instance, will no longer display a real image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. When this kind of a problem occurs and it's not noticed by the system or by an administrator, the data will be corrupted silently and in case this happens on a disk drive which is a part of a RAID array where the data is synchronized between various different drives, the corrupted file will be copied on all the other drives and the harm will become permanent. A number of frequently used file systems either do not feature real-time checks or don't have good ones which can detect an issue before the damage is done, so silent data corruption is a rather common matter on web hosting servers where large amounts of information are kept.

No Data Corruption & Data Integrity in Cloud Hosting

We warrant the integrity of the info uploaded in each and every cloud hosting account which is created on our cloud platform due to the fact that we use the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption using a unique checksum for each and every file. We will store your data on multiple SSD drives that function in a RAID, so exactly the same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all files on all the drives in real time and in case the checksum of any file differs from what it should be, the file system replaces that file with a healthy version from some other drive from the RAID. No other file system uses checksums, so it is possible for data to get silently corrupted and the bad file to be replicated on all drives over time, but since this can never happen on a server running ZFS, you won't have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you acquire one of our semi-dedicated hosting plans, you won't have to worry about silent data corruption because we use ZFS - a high level file system which keeps track of all 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. The file will be synchronized between multiple SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done instantly, so there will be no danger for any part of your content at any moment. In contrast, other file systems carry out checks only after a system failure, but since they do not use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a corrupted copy could be replicated on the other drives as well and you may lose precious info. Because this isn't the case with ZFS, we can guarantee the integrity of each and every file you upload no matter what.
