Data corruption is the damage of information caused by various hardware or software fails. After a file gets damaged, it will no longer work properly, so an application will not start or will give errors, a text file will be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an administrator, which makes it a serious problem for website hosting servers as problems are more likely to occur on larger in size hard disks where substantial volumes of info are located. If a drive is part of a RAID and the info on it is duplicated on other drives for redundancy, it is very likely that the damaged file will be treated as a regular one and will be duplicated on all of the drives, making the damage permanent. Lots of the file systems that operate on web servers nowadays often are not able to identify corrupted files right away or they need time-consuming system checks through which the server is not functioning.
No Data Corruption & Data Integrity in Web Hosting
In case you host your sites in a web hosting account with our firm, you don't have to worry about any of your data ever getting corrupted. We can guarantee that as our cloud hosting platform employs the outstanding ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each and every file. All info that you upload will be saved in a RAID i.e. simultaneously on many SSD drives. A lot of file systems synchronize the files between the different drives with this kind of a setup, but there is no real warranty that a file will not be corrupted. This may occur during the writing process on each drive and then a bad copy can be copied on all other drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all the drives instantly and when a corrupted file is located, it is replaced with a good copy with the correct checksum from another drive. In this way, your data will stay intact no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
In case you get one of our semi-dedicated hosting packages, you will not need to worry about silent file corruption because we use ZFS - an advanced file system which keeps track of all files in real time. Every time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between several SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from another drive. This happens immediately, so there will be no threat for any part of your content at any moment. In contrast, other file systems carry out checks after a system failure, but since they don't use anything similar to the checksums which ZFS uses, they cannot detect silently corrupted files, so a corrupted copy may be replicated on the rest of the drives as well and you can lose critical data. Because this is not the case with ZFS, we are able to guarantee the integrity of each and every file you upload no matter what.
