Data corruption is the damage of data because of various software or hardware fails. After a file gets corrupted, it will no longer function as it should, so an app will not start or shall give errors, a text file will be partially or completely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an admin, that makes it a serious problem for website hosting servers as problems are much more likely to occur on bigger hard drives where large volumes of info are stored. If a drive is part of a RAID and the info on it is duplicated on other drives for redundancy, it's more than likely that the damaged file will be treated as a good one and it'll be duplicated on all of the drives, making the harm permanent. A huge number of the file systems which run on web servers today often are unable to detect corrupted files immediately or they need time-consuming system checks through which the server is not working.
No Data Corruption & Data Integrity in Cloud Hosting
In case you host your sites in a cloud hosting account with our company, you will not need to worry about any of your data ever getting damaged. We can ensure that because our cloud hosting platform uses the reliable ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for every single file. Any kind of data that you upload will be stored in a RAID i.e. simultaneously on numerous SSDs. Many file systems synchronize the files between the separate drives with such a setup, but there's no real warranty that a file won't be corrupted. This could occur during the writing process on any drive and then a damaged copy may be copied on the other 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 the event that a corrupted file is found, it is replaced with a good copy with the correct checksum from another drive. By doing this, your data will remain intact no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server account will be resistant to silent data corruption since all our storage servers employ the innovative ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, in order to guarantee the integrity of every single file. When you upload content to your account, it'll be kept on a couple of redundant drives employed in a RAID i.e. the files shall be the same on all drives. All of the copies of a particular file will feature the same checksum on all drives and ZFS will compare the checksums of the copies in real time, and if it detects a mismatch, that will indicate that one of the copies is damaged, it will substitute that file with a healthy copy from one of the other disks. Even if there is a sudden blackout, the data on the servers won't get corrupted and there won't be any need for a time-consuming system check which other file systems perform after some malfunction, prolonging the time needed for the server to get back online. ZFS is the only file system that can truly protect your content from silent data corruption.
