Data corruption is the unintentional transformation of a file or the loss of info that often occurs during reading or writing. The reason can be hardware or software fail, and as a result, a file can become partially or entirely corrupted, so it'll no longer function properly since its bits will be scrambled or lost. An image file, for example, will no longer show an accurate image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. If such a problem appears and it's not identified by the system or by an administrator, the data will become corrupted silently and in case this happens on a drive which is part of a RAID array where the info is synced between various drives, the corrupted file shall be reproduced on all the other drives and the harm will be permanent. Numerous frequently used file systems either do not feature real-time checks or don't have high quality ones that can detect a problem before the damage is done, so silent data corruption is a common issue on web hosting servers where huge amounts of data are kept.
No Data Corruption & Data Integrity in Hosting
If you host your websites in a hosting
account from our firm, you don't have to worry about your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform works with the reliable ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for every single file. Any kind of information that you upload will be saved in a RAID i.e. simultaneously on multiple SSD drives. Many file systems synchronize the files between the different drives using this type of a setup, but there's no real guarantee that a file won't be corrupted. This can occur during the writing process on any drive and after that a damaged copy can be copied on the rest of the drives. What is different on our platform is that ZFS analyzes the checksums of all files on all the drives right away and if a corrupted file is found, it's replaced with a good copy with the correct checksum from another drive. By doing this, your info will continue to be unharmed no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not encounter any silent data corruption issues in case you get one of our semi-dedicated hosting
solutions because the ZFS file system that we take advantage of on our cloud hosting platform uses checksums in order to guarantee that all of your files are intact all the time. A checksum is a unique digital fingerprint that is given to each and every file stored on a server. As we store all content on multiple drives at the same time, 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 in real time. If 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 probability of the corrupted copy to be synchronized on the rest of the hard drives. ZFS is the sole file system available on the market which uses checksums, which makes it much more dependable than other file systems which are not able to identify silent data corruption and duplicate bad files across hard drives.
