Data corruption is the damage of info due to various software or hardware problems. The moment a file gets damaged, it will no longer function as it should, so an app will not start or will give errors, a text file could be partially or fully unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an admin, which makes it a serious problem for hosting servers as fails are much more likely to happen on larger hard disk drives where significant volumes of info are located. In case a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it's very likely that the damaged file will be treated as a healthy one and it will be duplicated on all the drives, making the harm permanent. A lot of the file systems which operate on web servers these days often are unable to detect corrupted files right away or they need time-consuming system checks through which the server is not functioning.
No Data Corruption & Data Integrity in Cloud Hosting
We guarantee the integrity of the information uploaded in any cloud hosting
account which is generated on our cloud platform as we employ the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption via a unique checksum for every single file. We shall store your info on a number of SSD drives that function in a RAID, so identical files will exist on several places simultaneously. ZFS checks the digital fingerprint of all the files on all drives in real time and if the checksum of any file is different from what it has to be, the file system swaps that file with a healthy version from a different drive in the RAID. No other file system uses checksums, so it is easy for data to be silently damaged and the bad file to be duplicated on all drives over time, but since this can never happen on a server using ZFS, you won't have to concern yourself with the integrity of your info.
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 make use of the reliable ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, to verify the integrity of each and every file. When you upload content to your account, it will be stored on several redundant drives being employed in a RAID i.e. the files will be the same on all disk drives. All of the copies of a given file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies in real time, so if it detects a mismatch, which will indicate that one of the copies is damaged, it will swap that file with a good copy from one of the other drives. Even if there is an unexpected power loss, the data on the servers won't be corrupted and there won't be any need for a time-consuming system check that other file systems perform following some malfunction, lengthening the time needed for the server to go back online. ZFS is the sole file system which can truly protect your content from silent data corruption.
