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 could become partially or entirely corrupted, so it will no longer work properly since its bits will be scrambled or lacking. An image file, for instance, will no longer display an actual image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. If such an issue occurs and it's not noticed by the system or by an administrator, the data will be corrupted silently and in case this happens on a drive that is a part of a RAID array where the information is synchronized between different drives, the corrupted file shall be reproduced on all other drives and the damage will be long term. Numerous popular file systems either don't feature 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 rather common matter on internet hosting servers where huge amounts of information are stored.

No Data Corruption & Data Integrity in Shared Hosting

We've tackled the problem of silent data corruption on all our shared hosting servers by using the leading-edge Z file system, or ZFS. The latter is superior to other file systems since it is the only one out there which checks all files right away by employing a checksum - a digital identifier which is unique for each and every file. When you upload content to your account, it'll be stored on several SSD drives and continually synchronized between them for redundancy. ZFS regularly examines 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's no risk that a corrupted file may remain or may be copied on the other SSDs. ZFS requires plenty of physical memory in order to execute the real-time checks and the advantage of our cloud website hosting platform is that we employ multiple very powerful servers working together. If you host your websites with us, your info will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be protected against silent data corruption since all our storage servers employ the advanced ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, so as to ensure the integrity of every single file. When you upload content to your account, it'll be saved on several redundant drives working in a RAID i.e. the files shall be the same across all drives. All copies of a given file will feature the same checksum on all hard drives and ZFS will compare the checksums of the duplicates quickly, so if it registers a mismatch, which will indicate that one of the copies is corrupted, it will replace that file with a healthy copy from one of the other drives. Even if there's a sudden blackout, the data on the servers won't be corrupted and there will not be any need for a time-consuming system check which other file systems perform following some failure, extending the time needed for the server to return online. ZFS is the file system that can really protect your content from silent data corruption.
