Data corruption is the unintended transformation of a file or the losing of information which usually occurs during reading or writing. The reason may be hardware or software failure, and as a result, a file could become partially or fully corrupted, so it will no longer function correctly as its bits will be scrambled or missing. An image file, for instance, will no longer display an actual 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 occurs and it's not found by the system or by an admin, the data will become corrupted silently and if this happens on a disk drive that's a part of a RAID array where the info is synchronized between various different drives, the corrupted file shall be copied on all the other drives and the damage will become long term. A large number of widely used file systems either don't offer real-time checks or do not have good ones which can detect a problem before the damage is done, so silent data corruption is a common issue on web hosting servers where substantial amounts of data are kept.

No Data Corruption & Data Integrity in Hosting

We warrant the integrity of the data uploaded in any hosting account which is created on our cloud platform due to the fact that we employ the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption via a unique checksum for every single file. We will store your info on a number of SSD drives which work in a RAID, so the same files will be accessible on several places at the same time. ZFS checks the digital fingerprint of all files on all drives in real time and in the event that the checksum of any file is different from what it needs to be, the file system swaps that file with an undamaged version from a different drive within the RAID. There's no other file system that uses checksums, so it's easy for data to become silently damaged and the bad file to be reproduced on all drives over time, but since that can never happen on a server running ZFS, you don't have to worry about the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You won't have to deal with any kind of silent data corruption issues should you buy one of our semi-dedicated hosting plans due to the fact that the ZFS file system that we employ on our cloud hosting platform uses checksums to make sure that all of your files are intact all the time. A checksum is a unique digital fingerprint which is allotted to each and every file kept on a server. As we store all content on a number of drives simultaneously, the same file uses the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives in real time. In case it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy right away, avoiding any probability of the corrupted copy to be synchronized on the rest of the hard disks. ZFS is the only file system on the market which uses checksums, which makes it much more dependable than other file systems that cannot detect silent data corruption and duplicate bad files across drives.
