Data corruption is the accidental change of a file or the loss of information which usually occurs during reading or writing. The reason can be hardware or software malfunction, and due to this fact, a file may become partially or fully corrupted, so it will no longer function properly because its bits will be scrambled or lacking. An image file, for example, will no longer display an authentic image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. If this kind of a problem occurs and it's not noticed by the system or by an administrator, the data will become corrupted silently and if this happens on a drive which is part of a RAID array where the information is synchronized between various different drives, the corrupted file will be replicated on all the other drives and the damage will become long term. A number of commonly used file systems either do not feature real-time checks or don't have good ones that can detect a problem before the damage is done, so silent data corruption is a very common matter on hosting servers where substantial amounts of data are kept.
No Data Corruption & Data Integrity in Website Hosting
We warrant the integrity of the data uploaded in each and every website hosting account which is created on our cloud platform since we use the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption using a unique checksum for every single file. We'll store your info on multiple SSD drives that operate in a RAID, so the same files will be available on several places at the same time. ZFS checks the digital fingerprint of all files on all of the drives in real time and in case the checksum of any file is different from what it should be, the file system swaps that file with a healthy copy from some other drive inside the RAID. No other file system uses checksums, so it's possible for data to be silently corrupted and the bad file to be duplicated on all drives over time, but since this can never happen on a server running ZFS, you don't have to worry about the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server account will be protected against silent data corruption as all our storage servers make use of the advanced ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order to ensure the integrity of every single file. When you upload content to your account, it will be kept on several redundant drives being employed in a RAID i.e. the files shall be the same on all disk drives. All copies of a specific file will have the same checksum on all hard disks and ZFS will compare the checksums of the duplicates right away, and if it detects a mismatch, that would indicate that one of the copies is damaged, it'll swap that file with a good copy from one of the other disks. Even if there's an unexpected power failure, the data on the servers won't be corrupted and there will not be any need for a time-consuming system check which other file systems perform after some breakdown, prolonging the time needed for the server to get back online. ZFS is the file system that can really protect your content from silent data corruption.
