Data corruption is the accidental change of a file or the loss of information that usually occurs during reading or writing. The reason may be hardware or software malfunction, and for that reason, a file could become partially or fully corrupted, so it'll no longer work correctly since its bits will be scrambled or lacking. An image file, for instance, will no longer present an actual image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. In case this kind of a problem occurs and it is not identified by the system or by an admin, the data will get corrupted silently and when this happens on a disk drive that's a part of a RAID array where the data is synchronized between different drives, the corrupted file will be duplicated on all the other drives and the harm will become long term. A large number of popular file systems either don't offer 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 issue on internet hosting servers where large volumes of info are kept.
No Data Corruption & Data Integrity in Hosting
In case you host your sites in a hosting
account with our firm, you do not need to worry about any of your data ever getting corrupted. We can guarantee that since our cloud hosting platform employs the cutting-edge ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each file. All information that you upload will be saved in a RAID i.e. simultaneously on many SSD drives. Many file systems synchronize the files between the separate drives with such a setup, but there is no real warranty that a file will not be corrupted. This may happen during the writing process on any drive and after that a bad copy can be copied on all other drives. What is different on our platform is that ZFS examines the checksums of all files on all drives right away and in the event that a corrupted file is found, it's replaced with a good copy with the correct checksum from another drive. In this way, your info 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 resistant to silent data corruption as all our storage servers make use of the efficient ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, to guarantee the integrity of each and every file. When you upload content to your account, it'll be saved on a couple of redundant drives being employed in a RAID i.e. the files will be the same across all disks. All copies of a given file will have the same checksum on all hard disks and ZFS will compare the checksums of the copies right away, so if it finds a mismatch, that would indicate that one of the copies is corrupted, it'll substitute that file with a good copy from one of the other drives. Even if there is an unforeseen power failure, the data on the servers won't become corrupted and there won't be any need for a time-consuming system check which other file systems perform after some failure, extending the time needed for the server to return online. ZFS is the file system which can truly protect your content from silent data corruption.
