Data corruption is the accidental modification of a file or the losing of info that usually occurs during reading or writing. The reason can be hardware or software fail, and because of this, a file could become partially or fully corrupted, so it will no longer function properly as its bits will be scrambled or missing. An image file, for instance, will no longer display a real image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. In case such a problem occurs and it's not noticed by the system or by an admin, the data will become corrupted silently and in case this happens on a drive that's a part of a RAID array where the information is synced between different drives, the corrupted file will be copied on all the other drives and the damage will become permanent. Many frequently used file systems either do not have real-time checks or do not have good ones which can detect an issue before the damage is done, so silent data corruption is a common matter on hosting servers where substantial volumes of information are stored.

No Data Corruption & Data Integrity in Shared Hosting

We guarantee the integrity of the info uploaded in each and every shared hosting account that is made on our cloud platform because we employ the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption using a unique checksum for each and every file. We'll store your info on a large number of NVMe drives which work in a RAID, so the same files will be present on several places at the same time. ZFS checks the digital fingerprint of all files on all of the drives in real time and if the checksum of any file differs from what it needs to be, the file system replaces that file with a healthy copy from a different drive from the RAID. There's no other file system which uses checksums, so it is possible for data to be silently corrupted and the bad file to be replicated on all drives over time, but since this can never happen on a server using ZFS, you do not 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 resistant to silent data corruption as all of our storage servers use the effective ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to guarantee the integrity of each and every file. When you upload content to your account, it will be stored on several redundant drives being employed in a RAID i.e. the files will be the same across all disk drives. All of the copies of a particular file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates right away, so if it discovers a mismatch, which would indicate that one of the copies is corrupted, it will swap 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 be corrupted and there won't be any need for a time-consuming system check which other file systems perform following some breakdown, lengthening the time needed for the server to go back online. ZFS is the only file system which can really protect your content from silent data corruption.
