Data corruption is the unintended change of a file or the losing of information which usually occurs during reading or writing. The reason may be hardware or software failure, and due to this fact, a file can become partially or entirely corrupted, so it'll no longer work as it should because its bits shall be scrambled or lacking. An image file, for example, will no longer display an authentic image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. In the event that such a problem appears and it's not recognized by the system or by an admin, the data will be corrupted silently and in case 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 reproduced on all the other drives and the harm will become permanent. Many frequently used file systems either do not feature real-time checks or do not have good ones that will detect a problem before the damage is done, so silent data corruption is a rather common problem on hosting servers where huge volumes of data are kept.
No Data Corruption & Data Integrity in Shared Web Hosting
If you host your Internet sites in a shared web hosting
account with our firm, you do not need to worry about any of your data ever getting damaged. We can ensure that because our cloud hosting platform employs the outstanding ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each file. All of the information that you upload will be kept in a RAID i.e. simultaneously on multiple SSD drives. All file systems synchronize the files between the separate drives with this type of a setup, but there's no real warranty that a file will not get corrupted. This may happen during the writing process on each drive and afterwards a damaged copy can be copied on the rest of the drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all the drives live and when a corrupted file is identified, it's swapped with a good copy with the correct checksum from another drive. By doing this, your info will remain unharmed no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be shielded from silent data corruption as all of our storage servers use the state-of-the-art ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to ensure the integrity of every single 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 drives. All of the copies of a specific file will have the same checksum on all hard disks and ZFS will compare the checksums of the duplicates quickly, so if it discovers a mismatch, which would indicate that one of the copies is damaged, it'll substitute that file with a good copy from one of the other drives. Even if there's a sudden power failure, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check which other file systems perform following some breakdown, extending the time needed for the server to go back online. ZFS is the sole file system that can really protect your content from silent data corruption.
