Data corruption is the accidental transformation of a file or the losing of info which usually occurs during reading or writing. The reason may be hardware or software failure, and due to this fact, a file could become partially or fully corrupted, so it'll no longer work properly as its bits shall be scrambled or lacking. An image file, for example, will no longer present an authentic image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. In the event that this kind of an issue occurs and it is not found by the system or by an administrator, the data will get corrupted silently and if this happens on a drive that's a part of a RAID array where the data is synchronized between various different drives, the corrupted file will be duplicated on all other drives and the damage will become permanent. A number of frequently used file systems either don't have real-time checks or don't have high quality ones which will detect a problem before the damage is done, so silent data corruption is a rather common issue on web hosting servers where large amounts of information are kept.

No Data Corruption & Data Integrity in Hosting

We have tackled the problem of silent data corruption on our hosting servers by using the leading-edge Z file system, or ZFS. The latter is better than other file systems as it is the only one on the market that checks all the files immediately by employing a checksum - a digital identifier that's unique for each file. When you upload content to your account, it'll be stored on several SSD drives and constantly synchronized between them for redundancy. ZFS constantly examines the checksum of all files and in the event that any file is detected as damaged, it's replaced quickly with a good copy from some other disk. As this happens in real time, there's no risk that a damaged file may remain or may be duplicated on the rest of the SSDs. ZFS needs lots of physical memory to execute the real-time checks and the benefit of our cloud hosting platform is that we use multiple powerful servers working together. In case you host your Internet sites with us, your information will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be protected against silent data corruption as all of our storage servers employ the efficient ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to verify the integrity of each and every file. When you upload content to your account, it'll be kept on a couple of redundant drives operating in a RAID i.e. the files shall be the same on all disks. All the copies of a particular file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies right away, and if it discovers a mismatch, which would indicate that one of the copies is corrupted, it'll swap that file with a good copy from one of the other disks. Even if there is a sudden blackout, the data on the servers will not get corrupted and there will not be any need for a time-consuming system check that other file systems perform after some malfunction, prolonging the time needed for the server to get back online. ZFS is the file system that can really protect your content from silent data corruption.
