Data corruption is the unintentional 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 as a consequence, a file can become partially or fully corrupted, so it'll no longer function properly since its bits will be scrambled or missing. An image file, for example, will no longer show an actual image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. In case such a problem appears and it is not identified by the system or by an administrator, the data will be corrupted silently and if this happens on a disk drive which is a part of a RAID array where the info is synchronized between various drives, the corrupted file shall be duplicated on all other drives and the damage will become permanent. Many frequently used file systems either do not offer real-time checks or don't have good ones which can detect a problem before the damage is done, so silent data corruption is a very common matter on hosting servers where huge volumes of info are kept.

No Data Corruption & Data Integrity in Shared Website Hosting

We've resolved the problem of silent data corruption on all our shared website hosting servers by using the hi-tech Z file system, or ZFS. The latter is more advanced than other file systems as it is the only one on the market that checks all files instantly by using a checksum - a digital identifier that is unique for every single file. When you upload content to your account, it will be stored on several SSD drives and continually synced between them for redundancy. ZFS regularly analyzes the checksum of all files and if any file is detected as damaged, it's replaced instantly with a good copy from another disk. As this happens in real time, there's no risk that a corrupted file may remain or may be duplicated on the other SSDs. ZFS needs lots of physical memory in order to perform the real-time checks and the advantage of our cloud website hosting platform is that we employ multiple powerful servers working together. In case you host your Internet sites with us, your data will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be resistant to silent data corruption since all our storage servers use the effective ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to guarantee the integrity of every single file. When you upload content to your account, it'll be kept on several redundant drives in a RAID i.e. the files shall be the same across all disk drives. All copies of a specific file will feature the same checksum on all hard disks and ZFS will compare the checksums of the duplicates right away, so if it detects a mismatch, that will 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 an unexpected blackout, the data on the servers won't become corrupted and there will not be any need for a time-consuming system check which other file systems perform after some failure, lengthening the time needed for the server to go back online. ZFS is the sole file system which can truly protect your content from silent data corruption.
