Data corruption is the accidental modification of a file or the loss of information that usually occurs during reading or writing. The reason can be hardware or software fail, and because of this, a file can become partially or fully corrupted, so it will no longer function as it should since its bits will be scrambled or lacking. An image file, for instance, will no longer show an accurate image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. When such a problem appears and it's not recognized by the system or by an admin, the data will be corrupted silently and if this happens on a disk drive that is a part of a RAID array where the information is synced between various different drives, the corrupted file will be duplicated on all the other drives and the damage will become long term. Numerous widely used file systems either don't have real-time checks or don't have high quality ones which can detect an issue before the damage is done, so silent data corruption is a rather common matter on internet hosting servers where large amounts of info are stored.
No Data Corruption & Data Integrity in Shared Hosting
If you host your Internet sites in a shared hosting
account from our firm, you do not have to worry about your data ever getting corrupted. We can ensure that as our cloud hosting platform uses the reliable ZFS file system. The aforementioned is the only file system which works with 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 many different SSDs. Many file systems synchronize the files between the separate drives using such 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 after that a bad copy may be copied on the other drives. What makes the difference on our platform is the fact that ZFS analyzes the checksums of all files on all the drives in real time and in the event that a corrupted file is discovered, it's swapped with a good copy with the correct checksum from another drive. This way, your information will remain undamaged no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be shielded from silent data corruption because all of our storage servers use the advanced ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to guarantee the integrity of each file. When you upload content to your account, it will be kept on a couple of redundant drives employed 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 disks and ZFS will compare the checksums of the duplicates right away, so if it identifies a mismatch, that will indicate that one of the copies is corrupted, it'll replace that file with a healthy copy from one of the other drives. Even if there is an unforeseen blackout, the data on the servers will not become corrupted and there won't be any need for a time-consuming system check which other file systems perform after some failure, prolonging the time needed for the server to go back online. ZFS is the only file system that can really protect your content from silent data corruption.
