Data corruption is the unintended transformation of a file or the losing of info that often occurs during reading or writing. The reason could be hardware or software failure, and as a consequence, a file could become partially or entirely corrupted, so it'll no longer function properly since its bits will be scrambled or missing. An image file, for instance, will no longer show an authentic 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 such a problem occurs and it's not found by the system or by an admin, the data will get corrupted silently and if this happens on a drive which is a part of a RAID array where the information is synced between different drives, the corrupted file shall be replicated on all other drives and the damage will be permanent. A large number of commonly used file systems either don't feature real-time checks or do not have high quality ones which can detect an issue 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 Shared Hosting

We warrant the integrity of the data uploaded in every shared hosting account that is made on our cloud platform since we use the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption through a unique checksum for every single file. We will store your information on a large number of SSD drives which work in a RAID, so the exact same files will be present on several places simultaneously. 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 should be, the file system swaps that file with an undamaged copy from a different drive within the RAID. There's no other file system that uses checksums, so it's possible for data to become silently corrupted and the bad file to be reproduced on all drives with 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 Servers

You will not have to deal with any silent data corruption issues should you purchase one of our semi-dedicated server plans due to the fact that the ZFS file system that we use on our cloud hosting platform uses checksums to guarantee that all of your files are intact all of the time. A checksum is a unique digital fingerprint that is allotted to each and every file kept on a server. Due to the fact that we store all content on multiple drives simultaneously, the same file has the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. If it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy right away, avoiding any possibility of the damaged copy to be synchronized on the remaining hard disks. ZFS is the sole file system you can find that uses checksums, which makes it much more reliable than other file systems which are not able to identify silent data corruption and copy bad files across drives.
