Data corruption is the unintended transformation of a file or the losing of info that often occurs during reading or writing. The reason could be hardware or software fail, and due to this fact, a file could become partially or completely corrupted, so it will no longer work as it should since its bits shall be scrambled or lacking. An image file, for example, will no longer present an authentic image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. When such an issue appears and it's not found by the system or by an admin, the data will get corrupted silently and when this happens on a disk drive which is part of a RAID array where the information is synchronized between various drives, the corrupted file will be copied on all of the other drives and the damage will be permanent. Numerous widespread file systems either don't offer real-time checks or do not have good ones which will detect a problem before the damage is done, so silent data corruption is a common problem on web hosting servers where large volumes of data are stored.

No Data Corruption & Data Integrity in Cloud Hosting

We have dealt with the problem of silent data corruption on all our cloud hosting servers by using the amazing Z file system, or ZFS. The latter is better than other file systems as it is the only one out there that checks all files right away by employing a checksum - a digital identifier that is unique for each and every file. When you upload content to your account, it'll be stored on several SSD drives and constantly synchronized between them for redundancy. ZFS regularly analyzes the checksum of all files and when any file is detected as corrupted, it is replaced immediately with a good copy from some other disk. As this happens in real time, there's no risk that a corrupted file may remain or may be duplicated on the remaining SSDs. ZFS needs lots of physical memory to perform the real-time checks and the advantage of our cloud web hosting platform is that we employ multiple very powerful servers working together. If you host your Internet sites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You won't encounter any kind of silent data corruption issues whatsoever if you buy one of our semi-dedicated hosting plans because the ZFS file system that we work with 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 that is allotted to each and every file stored on a server. As we store all content on multiple 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 right away. When 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 without delay, avoiding any chance of the damaged copy to be synchronized on the rest of the drives. ZFS is the only file system you can get which uses checksums, which makes it much more reliable than other file systems that cannot detect silent data corruption and copy bad files across hard drives.
