Data corruption is the accidental transformation of a file or the losing of info which often occurs during reading or writing. The reason can be hardware or software malfunction, and for that reason, a file could become partially or entirely corrupted, so it'll no longer function correctly because its bits shall be scrambled or missing. An image file, for instance, will no longer present an authentic image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. If this kind of a problem occurs and it's not noticed by the system or by an admin, the data will be corrupted silently and in case this happens on a disk drive that is part of a RAID array where the data is synced between different drives, the corrupted file shall be duplicated on all other drives and the harm will be long term. A large number of popular file systems either don't feature real-time checks or do not have high quality ones which can detect a problem before the damage is done, so silent data corruption is a common matter on web hosting servers where huge amounts of info are stored.
No Data Corruption & Data Integrity in Hosting
If you host your sites in a hosting
account with our company, you won't have to worry about any of your data ever getting corrupted. We can ensure that due to the fact that our cloud hosting platform uses the advanced ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for every single file. All the data that you upload will be kept in a RAID i.e. simultaneously on a large number of SSDs. All file systems synchronize the files between the separate drives using this type of a setup, but there is no real guarantee that a file will not be corrupted. This can happen at the time of the writing process on any drive and then a corrupted copy can be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS analyzes the checksums of all files on all the drives live and if a corrupted file is located, it is swapped with a good copy with the correct checksum from another drive. By doing this, your information will stay unharmed no matter what, even if a whole drive fails.
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 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 a couple of redundant drives in a RAID i.e. the files shall be the same across all drives. All copies of a specific file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates in real time, and if it identifies a mismatch, that will indicate that one of the copies is damaged, it will replace that file with a good copy from one of the other disks. Even if there is a sudden power loss, the data on the servers will not become corrupted and there will not be any need for a time-consuming system check that other file systems perform after some malfunction, extending the time needed for the server to get back online. ZFS is the only file system that can truly protect your content from silent data corruption.
