No Data Corruption & Data Integrity
Find what ‘No Data Corruption & Data Integrity’ means for the info within your web hosting account.
Data corruption is the unintentional modification of a file or the loss of information which often occurs during reading or writing. The reason can be hardware or software malfunction, and as a consequence, a file can become partially or fully corrupted, so it will no longer work as it should as its bits will be scrambled or lacking. An image file, for instance, will no longer present an actual image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. If such an issue occurs and it is not identified by the system or by an admin, the data will get corrupted silently and in case this happens on a disk drive that's part of a RAID array where the info is synced between various drives, the corrupted file will be reproduced on all other drives and the harm will become long term. Many frequently used file systems either don't feature real-time checks or do not have good ones that will detect an issue before the damage is done, so silent data corruption is a rather common matter on web hosting servers where large amounts of info are kept.
No Data Corruption & Data Integrity in Shared Web Hosting
We guarantee the integrity of the info uploaded in each and every shared web hosting
account which is created on our cloud platform due to the fact that we use the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption via a unique checksum for every single file. We shall store your info on a number of SSD drives which work in a RAID, so exactly the same files will exist on several places at once. ZFS checks the digital fingerprint of all the files on all 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 a healthy copy from another drive from the RAID. No other file system 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 this can never happen on a server using ZFS, you will not have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any risk of files getting damaged silently because the servers where your semi-dedicated hosting
account will be created employ a powerful file system named ZFS. Its advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. Since we keep all content on a number of SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has saved. When there is a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and considering that it happens right away, there's no chance that a corrupted copy could remain on our hosting servers or that it can be duplicated to the other hard disks in the RAID. None of the other file systems work with this type of checks and in addition, even during a file system check after an unexpected electrical power failure, none of them will identify silently corrupted files. In comparison, ZFS doesn't crash after a power loss and the continual checksum monitoring makes a time-consuming file system check unnecessary.
