Data corruption is the unintentional transformation of a file or the loss of info which often occurs during reading or writing. The reason may be hardware or software malfunction, and due to this fact, a file could become partially or completely corrupted, so it'll no longer function properly as its bits shall be scrambled or lacking. An image file, for instance, will no longer display a true image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etc. In case this kind of an issue occurs and it is not recognized by the system or by an administrator, the data will get corrupted silently and when this happens on a drive that is a part of a RAID array where the data is synchronized between various drives, the corrupted file will be replicated on all other drives and the damage will be long term. Numerous widespread file systems either do not offer real-time checks or don't have good ones which will detect an issue before the damage is done, so silent data corruption is a common problem on web hosting servers where large volumes of data are kept.
No Data Corruption & Data Integrity in Shared Hosting
In case you host your sites in a shared hosting account with our firm, you will not have to worry about any of your data ever getting damaged. We can ensure that since our cloud hosting platform works with the cutting-edge ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each file. All info that you upload will be stored in a RAID i.e. simultaneously on many SSD drives. All file systems synchronize the files between the separate drives using this kind of a setup, but there's no real guarantee that a file won't get corrupted. This can occur throughout the writing process on each drive and then a bad copy can be copied on all other drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all of the drives right away and when a corrupted file is identified, it is replaced with a good copy with the correct checksum from another drive. This way, your data will continue to be intact no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You won't encounter any silent data corruption issues in case you get one of our semi-dedicated hosting packages since the ZFS file system that we use on our cloud hosting platform uses checksums in order to make sure that all files are undamaged all of the time. A checksum is a unique digital fingerprint that is assigned to each and every file kept on a server. Since we store all content on multiple drives at the same time, the same file has the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives in real time. If it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy right away, avoiding any possibility of the damaged copy to be synchronized on the rest of the drives. ZFS is the only file system you can find which uses checksums, which makes it much more dependable than other file systems that are not able to detect silent data corruption and copy bad files across drives.
