Data corruption is the unintended transformation of a file or the losing of information that usually occurs during reading or writing. The reason may be hardware or software fail, and for that reason, a file may become partially or fully corrupted, so it will no longer work correctly since its bits will be scrambled or lost. An image file, for example, will no longer present an authentic image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. If this kind of an issue occurs and it isn't identified by the system or by an administrator, the data will get corrupted silently and when this happens on a disk drive that is a part of a RAID array where the info is synced between different drives, the corrupted file shall be reproduced on all of the other drives and the damage will become long term. Numerous commonly used file systems either do not offer real-time checks or do not have good ones that will detect a problem before the damage is done, so silent data corruption is a common matter on internet hosting servers where large amounts of info are stored.
No Data Corruption & Data Integrity in Website Hosting
We guarantee the integrity of the data uploaded in each website hosting
account that is made on our cloud platform since we employ 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 each and every file. We shall store your information on a large number of SSD drives that operate in a RAID, so identical files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all the drives in real time and in the event that the checksum of any file differs from what it needs to be, the file system swaps that file with a healthy copy from another drive within the RAID. There's no other file system that uses checksums, so it is easy for data to get silently damaged and the bad file to be reproduced on all drives over time, but since that can never happen on a server using ZFS, you don't have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You will not encounter any kind of silent data corruption issues should 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 ensure that all the files are intact at all times. A checksum is a unique digital fingerprint which is given to each and every file stored on a server. Because we store all content on a number of drives at the same time, the same file uses the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives in real time. If 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 possibility of the bad copy to be synchronized on the rest of the hard disks. ZFS is the sole file system you will find that uses checksums, which makes it much more reliable than other file systems which are not able to identify silent data corruption and duplicate bad files across drives.
