Data corruption is the damage of information because of various hardware or software failures. The moment a file is damaged, it will no longer function as it should, so an app will not start or shall give errors, a text file could be partially or entirely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an administrator, that makes it a significant problem for web hosting servers as problems are more likely to occur on bigger hard disk drives where significant volumes of information are stored. In case a drive is part of a RAID and the data on it is copied on other drives for redundancy, it's likely that the damaged file will be treated as a healthy one and will be duplicated on all drives, making the harm permanent. Lots of the file systems which operate on web servers nowadays often cannot find corrupted files immediately or they need time-consuming system checks during which the server isn't functioning.
No Data Corruption & Data Integrity in Website Hosting
If you host your sites in a website hosting account from our company, you do not 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 aforementioned is the only file system which uses checksums, or unique digital fingerprints, for every single file. Any kind of information that you upload will be stored in a RAID i.e. simultaneously on many NVMes. A lot of file systems synchronize the files between the separate drives with this kind of a setup, but there's no real guarantee that a file won't be corrupted. This can happen during the writing process on each drive and afterwards a corrupted copy may be copied on the rest of the drives. What is different on our platform is that ZFS compares the checksums of all files on all of the drives instantly and in the event that a corrupted file is identified, it's swapped with a good copy with the correct checksum from some other drive. In this way, your info will stay unharmed no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not need to deal with any silent data corruption issues should you buy one of our semi-dedicated hosting packages due to the fact that the ZFS file system that we take advantage of on our cloud hosting platform uses checksums in order to guarantee that all the files are undamaged at all times. A checksum is a unique digital fingerprint that is given to each and every file stored on a server. Due to the fact that we store all content on a number of drives simultaneously, the same file uses the same checksum on all the 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 has to be, it replaces that file with a healthy copy right away, avoiding any possibility of the bad copy to be synchronized on the other hard drives. ZFS is the sole file system you will find that uses checksums, which makes it much more dependable than other file systems which cannot identify silent data corruption and copy bad files across hard drives.
