Data corruption is the damage of information because of various hardware or software failures. Once a file is corrupted, it will no longer function properly, so an app will not start or shall give errors, a text file can be partially or entirely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of info getting harmed without any acknowledgement by the system or an administrator, that makes it a significant problem for hosting servers as fails are very likely to happen on larger hard drives where significant volumes of info are kept. When a drive is a part of a RAID and the data on it is copied on other drives for redundancy, it is more than likely that the bad file will be treated as a standard one and it'll be duplicated on all drives, making the harm permanent. Lots of the file systems that run on web servers these days often cannot recognize corrupted files instantly or they need time-consuming system checks through which the server isn't operational.
No Data Corruption & Data Integrity in Hosting
In case you host your Internet sites in a hosting account from our firm, you won't have to worry about your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform uses the advanced ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each file. All data that you upload will be stored in a RAID i.e. simultaneously on multiple SSD drives. A lot of 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 be corrupted. This can occur at the time of the writing process on any drive and afterwards a corrupted copy can 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 drives live and in case a corrupted file is found, it's replaced with a good copy with the correct checksum from another drive. By doing this, your data will remain undamaged no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You will not have to deal with any kind of silent data corruption issues whatsoever should you purchase one of our semi-dedicated server solutions because the ZFS file system that we work with on our cloud hosting platform uses checksums in order to guarantee that all the files are undamaged all of the time. A checksum is a unique digital fingerprint that is assigned to each and every file stored on a server. Since we store all content on multiple drives simultaneously, the same file uses the same checksum on all of 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 without delay, avoiding any probability of the corrupted copy to be synchronized on the rest of the hard drives. ZFS is the sole file system on the market that uses checksums, which makes it far superior to other file systems which cannot identify silent data corruption and copy bad files across drives.
