Data corruption is the damage of info caused by various hardware or software failures. Once a file gets corrupted, it will no longer function as it should, so an app will not start or will give errors, a text file will be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an admin, that makes it a serious problem for hosting servers as problems are more likely to happen on bigger hard drives where large volumes of information are located. When a drive is part of a RAID and the information on it is copied on other drives for redundancy, it's very likely that the damaged file will be treated as a standard one and will be copied on all drives, making the harm permanent. Lots of the file systems which run on web servers today often cannot discover corrupted files right away or they need time-consuming system checks during which the server is not operational.
No Data Corruption & Data Integrity in Hosting
In case you host your Internet sites in a hosting account with our company, you do not need to worry about your data ever getting damaged. We can ensure that because our cloud hosting platform employs the advanced ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each file. Any kind of information that you upload will be stored in a RAID i.e. simultaneously on numerous NVMe drives. All the file systems synchronize the files between the separate drives using such a setup, but there's no real warranty that a file will not get corrupted. This could happen at the time of the writing process on each drive and afterwards a bad copy may be copied on all other drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all of the drives in real time and when a corrupted file is discovered, it's substituted with a good copy with the correct checksum from some other drive. In this way, your data will continue to be unharmed no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not have to deal with any kind of silent data corruption issues if 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 make sure that all the files are undamaged all the time. A checksum is a unique digital fingerprint which is allotted to each and every file kept on a server. Since 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 right away. In case 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 corrupted copy to be synchronized on the other hard disks. ZFS is the only file system you can find that uses checksums, which makes it much more dependable than other file systems which cannot identify silent data corruption and duplicate bad files across hard drives.
