Data corruption is the unintentional modification of a file or the loss of information that often occurs during reading or writing. The reason can be hardware or software failure, and as a consequence, a file can become partially or entirely corrupted, so it will no longer work as it should since its bits will be scrambled or lacking. An image file, for instance, will no longer present a real image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. When such a problem appears and it isn't identified by the system or by an administrator, the data will get corrupted silently and if this happens on a disk drive that is a part of a RAID array where the information is synchronized between different drives, the corrupted file will be reproduced on all the other drives and the damage will be permanent. A number of commonly used file systems either don't feature real-time checks or don't have high quality ones that can detect a problem before the damage is done, so silent data corruption is a rather common problem on web hosting servers where huge amounts of information are stored.

No Data Corruption & Data Integrity in Shared Hosting

We warrant the integrity of the info uploaded in each shared hosting account that is made on our cloud platform due to the fact that we work with the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption thanks to a unique checksum for every single file. We will store your info on multiple SSD drives which operate in a RAID, so the exact same files will exist on several places at once. 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 has to be, the file system replaces that file with an undamaged version from another drive from the RAID. No other file system uses checksums, so it is possible for data to become silently damaged and the bad file to be reproduced on all drives with time, but since that can never happen on a server using ZFS, you don't have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not experience any kind of silent data corruption issues in case you buy one of our semi-dedicated server plans since the ZFS file system that we use on our cloud hosting platform uses checksums in order to guarantee that all the files are intact all the time. A checksum is a unique digital fingerprint that is given to each and every file saved 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 the drives and what ZFS does is that it compares the checksums between the different drives right away. In case 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 without delay, avoiding any possibility of the damaged copy to be synchronized on the remaining drives. ZFS is the only file system you will find that uses checksums, which makes it much more reliable than other file systems that cannot detect silent data corruption and copy bad files across drives.
