Data corruption is the unintended modification of a file or the loss of info that usually occurs during reading or writing. The reason could be hardware or software malfunction, and consequently, a file could become partially or fully corrupted, so it'll no longer function correctly since its bits shall be scrambled or lost. An image file, for instance, will no longer show a true image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. In the event that this kind of a problem appears and it is not noticed by the system or by an administrator, the data will become corrupted silently and when this happens on a drive which is part of a RAID array where the information is synchronized between various different drives, the corrupted file shall be replicated on all the other drives and the damage will be long term. Many popular file systems either do not feature real-time checks or do not have high quality ones that can detect a problem before the damage is done, so silent data corruption is a rather common problem on internet hosting servers where huge volumes of data are kept.
No Data Corruption & Data Integrity in Cloud Hosting
We guarantee the integrity of the information uploaded in each and every cloud hosting
account which is created on our cloud platform since we employ the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption via a unique checksum for each and every file. We shall store your information on a large number of SSD drives which function in a RAID, so identical files will be accessible on several places at the same time. ZFS checks the digital fingerprint of all the files on all of 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 replaces that file with an undamaged copy from a different drive from the RAID. There's no other file system which uses checksums, so it's easy for data to be silently damaged and the bad file to be duplicated on all drives with time, but since this can never happen on a server running ZFS, you won't have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not encounter any silent data corruption issues in case you acquire one of our semi-dedicated hosting
packages due to the fact that the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to make sure that all of your files are undamaged all the time. A checksum is a unique digital fingerprint which is given to each and every file stored on a server. Since we store all content on multiple drives at the same time, the same file uses the same checksum on all 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 right away, avoiding any possibility of the corrupted copy to be synchronized on the rest of the hard disks. ZFS is the only file system you will find that uses checksums, which makes it far superior to other file systems which are unable to detect silent data corruption and duplicate bad files across hard drives.
