Data corruption is the accidental modification of a file or the loss of info which usually occurs during reading or writing. The reason may be hardware or software fail, and because of this, a file may become partially or entirely corrupted, so it'll no longer function properly as its bits will be scrambled or lacking. An image file, for example, will no longer display a true image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. In the event that such a problem appears and it's not identified by the system or by an administrator, the data will be corrupted silently and when this happens on a drive that's part of a RAID array where the information is synced between various different drives, the corrupted file will be reproduced on all of the other drives and the harm will become long term. A number of frequently used file systems either do not have real-time checks or do not have good ones that can detect a problem 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 Cloud Hosting

We have resolved the issue of silent data corruption on all of our cloud hosting servers by using the amazing Z file system, or ZFS. The latter is superior to other file systems because it is the only one on the market that checks all files right away by using a checksum - a digital identifier that's unique for each and every file. When you upload content to your account, it'll be stored on several SSD drives and continually synced between them for redundancy. ZFS constantly examines the checksum of all files and when any file is detected as damaged, it's replaced right away with a good copy from another disk. As this happens in real time, there is no risk that a bad file may remain or may be copied on the remaining SSDs. ZFS requires lots of physical memory in order to perform the real-time checks and the benefit of our cloud web hosting platform is that we use multiple powerful servers working together. If you host your websites with us, your information will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You won't experience any silent data corruption issues whatsoever in case you acquire one of our semi-dedicated hosting packages due to the fact that the ZFS file system that we employ on our cloud hosting platform uses checksums to ensure that all of your files are undamaged at all times. A checksum is a unique digital fingerprint which is given to each and every file kept on a server. Since we store all content on a number of drives simultaneously, the same file has the same checksum on all of the 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 without delay, avoiding any possibility of the corrupted copy to be synchronized on the other hard disks. ZFS is the sole file system out there that uses checksums, which makes it much more reliable than other file systems which cannot detect silent data corruption and copy bad files across drives.
