Data corruption is the accidental modification of a file or the loss of info which often occurs during reading or writing. The reason may be hardware or software fail, and consequently, a file could become partially or fully corrupted, so it will no longer function correctly since its bits shall be scrambled or missing. An image file, for example, will no longer show an accurate image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. In case this kind of an issue appears and it is not found by the system or by an admin, the data will be corrupted silently and when this happens on a drive which is a part of a RAID array where the data is synced between various different drives, the corrupted file will be replicated on all of the other drives and the harm will become long term. A large number of widespread file systems either don't have real-time checks or don't have good ones which can detect a problem before the damage is done, so silent data corruption is a common issue on internet hosting servers where substantial volumes of information are kept.
No Data Corruption & Data Integrity in Web Hosting
If you host your websites in a web hosting
account from our firm, you do not have to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform employs the outstanding ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for every single file. All of the data that you upload will be saved in a RAID i.e. simultaneously on many SSD drives. All the file systems synchronize the files between the different drives with such a setup, but there is no real warranty that a file won't get corrupted. This may occur at the time of the writing process on any drive and then a corrupted copy may be copied on the other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all the drives immediately and if a corrupted file is identified, it is substituted with a good copy with the correct checksum from some other drive. By doing this, your data will remain undamaged no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be shielded from silent data corruption as all our storage servers use the state-of-the-art ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, so as to verify the integrity of each and every file. When you upload content to your account, it will be stored on several redundant drives operating in a RAID i.e. the files will be the same on all disks. All copies of a given file will feature the same checksum on all hard disks and ZFS will compare the checksums of the copies right away, so if it detects a mismatch, that will indicate that one of the copies is corrupted, it'll substitute that file with a healthy copy from one of the other disks. Even if there's an unexpected power loss, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check that other file systems perform following some breakdown, extending the time needed for the server to get back online. ZFS is the only file system that can truly protect your content from silent data corruption.
