Data corruption is the unintended change of a file or the losing of info that usually occurs during reading or writing. The reason can be hardware or software malfunction, and as a result, a file could become partially or entirely corrupted, so it'll no longer function as it should as its bits will be scrambled or lacking. An image file, for instance, 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, and so on. When this kind of an issue appears and it is not identified by the system or by an admin, the data will be corrupted silently and when this happens on a drive that's a part of a RAID array where the information is synced between various drives, the corrupted file will be reproduced on all other drives and the damage will be permanent. Numerous widely used file systems either don't offer real-time checks or do not have high quality ones that will detect a problem before the damage is done, so silent data corruption is a common matter on web hosting servers where large amounts of data are kept.

No Data Corruption & Data Integrity in Hosting

We've dealt with the issue of silent data corruption on all of our hosting servers by using the advanced Z file system, or ZFS. The latter is superior to other file systems since it is the only one out there which checks all the files instantly by using a checksum - a digital identifier that's unique for each file. When you upload content to your account, it will be stored on several SSD drives and constantly synchronized between them for redundancy. ZFS constantly analyzes the checksum of all files and if any file is detected as corrupted, it's replaced immediately with a good copy from another disk. As this happens in real time, there is no risk that a corrupted file may remain or may be copied on the other SSDs. ZFS needs lots of physical memory to carry out the real-time checks and the benefit of our cloud website hosting platform is that we work with multiple powerful servers working together. If you host your sites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be resistant to silent data corruption as all of our storage servers use the innovative ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to ensure the integrity of each and every file. When you upload content to your account, it will be placed on a couple of redundant drives being employed in a RAID i.e. the files will be the same on all drives. All of the copies of a given file will feature the same checksum on all hard drives and ZFS will compare the checksums of the duplicates right away, and if it identifies a mismatch, that will indicate that one of the copies is corrupted, it'll substitute that file with a good copy from one of the other drives. Even if there's an unexpected power loss, the data on the servers won't get corrupted and there won't be any need for a time-consuming system check that other file systems perform after some breakdown, prolonging the time needed for the server to return online. ZFS is the sole file system that can really protect your content from silent data corruption.
