Data corruption is the accidental modification of a file or the losing of info that usually occurs during reading or writing. The reason could be hardware or software failure, and consequently, a file can become partially or completely corrupted, so it will no longer work correctly because its bits will be scrambled or lost. An image file, for example, will no longer display a true image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. When this kind of a problem appears and it isn't recognized 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 replicated on all of the other drives and the harm will become long term. A 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 very common problem on web hosting servers where large volumes of information are kept.

No Data Corruption & Data Integrity in Shared Hosting

We warrant the integrity of the info uploaded in every single shared hosting account that is created on our cloud platform as we work with the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption via a unique checksum for every single file. We will store your info on multiple SSD drives that operate in a RAID, so exactly the same files will exist on several places concurrently. ZFS checks the digital fingerprint of all files on all the drives in real time and in the event that the checksum of any file differs from what it should be, the file system replaces that file with a healthy copy from a different drive within the RAID. No other file system uses checksums, so it is possible for data to get silently damaged and the bad file to be duplicated on all drives over time, but since that can never happen on a server using ZFS, you won't have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be protected against silent data corruption as all of our storage servers make use of the reliable ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, so as to ensure the integrity of each and every file. When you upload content to your account, it'll be placed on several redundant drives employed in a RAID i.e. the files will be the same across all disk drives. All of the copies of a specific file will have the same checksum on all drives and ZFS will compare the checksums of the copies quickly, and if it identifies a mismatch, that will indicate that one of the copies is corrupted, it will substitute that file with a healthy copy from one of the other drives. Even if there is a sudden power loss, the data on the servers won't get corrupted and there won't be any need for a time-consuming system check that other file systems perform after some failure, lengthening the time needed for the server to get back online. ZFS is the file system that can truly protect your content from silent data corruption.
