Data corruption is the unintentional modification of a file or the loss of information that often occurs during reading or writing. The reason could be hardware or software failure, and due to this fact, a file can become partially or entirely corrupted, so it will no longer function as it should since its bits shall be scrambled or lost. An image file, for instance, will no longer present an authentic image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. In the event that this kind of a problem occurs and it's not identified by the system or by an administrator, the data will become corrupted silently and when this happens on a disk drive that's a part of a RAID array where the information is synced between various drives, the corrupted file will be reproduced on all other drives and the damage will become long term. A number of commonly used file systems either do not feature real-time checks or don't have good ones that will detect a problem before the damage is done, so silent data corruption is a rather common matter on hosting servers where huge amounts of data are kept.
No Data Corruption & Data Integrity in Cloud Hosting
In case you host your sites in a cloud hosting
account from our company, you don't need to worry about your data ever getting corrupted. We can guarantee that since our cloud hosting platform uses the cutting-edge ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each file. All data that you upload will be kept in a RAID i.e. simultaneously on numerous SSDs. All the file systems synchronize the files between the separate drives with this type of a setup, but there is no real warranty that a file won't get corrupted. This can occur at the time of the writing process on each drive and afterwards a corrupted copy may be copied on the rest of the drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all of the drives right away and in the event that a corrupted file is discovered, it's substituted with a good copy with the correct checksum from another drive. By doing this, your info will stay unharmed no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be protected against silent data corruption because all our storage servers employ the reliable ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, in order to ensure the integrity of every single file. When you upload content to your account, it'll be saved on a couple of redundant drives operating in a RAID i.e. the files will be the same on all disks. All copies of a particular file will have the same checksum on all drives and ZFS will compare the checksums of the copies in real time, so if it discovers a mismatch, which would indicate that one of the copies is corrupted, it will swap that file with a good copy from one of the other disks. Even if there's an unexpected blackout, the data on the servers will not 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 which can really protect your content from silent data corruption.
