Data corruption is the unintended transformation of a file or the loss of information which usually occurs during reading or writing. The reason may be hardware or software fail, and consequently, a file can become partially or entirely corrupted, so it'll no longer function correctly as its bits will be scrambled or lost. An image file, for example, will no longer display an accurate image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etc. When such an issue occurs and it's not noticed by the system or by an administrator, the data will get corrupted silently and in case this happens on a drive that is part of a RAID array where the info is synchronized between various different drives, the corrupted file will be duplicated on all other drives and the harm will become long term. A large number of popular file systems either don't offer real-time checks or don't have high quality ones that will detect a problem before the damage is done, so silent data corruption is a common issue on hosting servers where large amounts of data are kept.
No Data Corruption & Data Integrity in Shared Website Hosting
In case you host your sites in a shared website hosting account from 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 outstanding ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each and every file. All of the data that you upload will be saved in a RAID i.e. simultaneously on a number of SSDs. A lot of file systems synchronize the files between the different drives using this type of a setup, but there's no real warranty that a file won't be corrupted. This can happen during the writing process on any drive and afterwards a bad copy can be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all of the drives instantly and in case a corrupted file is found, it is swapped with a good copy with the correct checksum from some other drive. By doing this, your data will remain intact no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You won't have to deal with any silent data corruption issues should you buy one of our semi-dedicated server packages because the ZFS file system that we employ on our cloud hosting platform uses checksums to ensure that all the files are intact all of the time. A checksum is a unique digital fingerprint that is allotted to each and every file saved on a server. Due to the fact that we store all content on multiple drives simultaneously, the same file uses 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 probability of the damaged copy to be synchronized on the other hard disks. ZFS is the sole file system out there which uses checksums, which makes it much more dependable than other file systems which are unable to identify silent data corruption and duplicate bad files across drives.
