Data corruption is the unintended modification of a file or the losing of info which often occurs during reading or writing. The reason can be hardware or software fail, and consequently, a file may become partially or fully corrupted, so it will no longer work correctly since its bits shall be scrambled or lost. An image file, for example, will no longer display an actual image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. In case such a problem occurs and it is not noticed by the system or by an admin, the data will get corrupted silently and when this happens on a drive that is part of a RAID array where the information is synced between various drives, the corrupted file shall be replicated on all other drives and the harm will be long term. A number of widespread file systems either do not feature real-time checks or do not have high quality ones that can detect a problem before the damage is done, so silent data corruption is a rather common issue on web hosting servers where large amounts of information are kept.

No Data Corruption & Data Integrity in Hosting

We warrant the integrity of the info uploaded in each and every hosting account which is created on our cloud platform since we employ the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption via a unique checksum for each and every file. We shall store your info on a large number of NVMe drives which work in a RAID, so exactly the same files will exist on several places concurrently. ZFS checks the digital fingerprint of all of the files on all the drives in real time and in case the checksum of any file differs from what it needs to be, the file system replaces that file with an undamaged copy from another drive in the RAID. There's no other file system which uses checksums, so it's easy for data to get silently corrupted and the bad file to be replicated on all drives over time, but since that 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 protected against silent data corruption since all of our storage servers use the efficient ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, in order to guarantee the integrity of each file. When you upload content to your account, it'll be stored on a couple of redundant drives being employed in a RAID i.e. the files will be the same across all disks. All the copies of a particular file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates in real time, so if it discovers a mismatch, which will indicate that one of the copies is damaged, it'll substitute 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 become corrupted and there will not be any need for a time-consuming system check which other file systems perform after some breakdown, lengthening the time needed for the server to go back online. ZFS is the only file system that can truly protect your content from silent data corruption.
