Data corruption is the damage of data due to various hardware or software failures. Once a file gets damaged, it will no longer function correctly, so an application will not start or will give errors, a text file shall be partially or completely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an administrator, which makes it a serious problem for website hosting servers as fails are more likely to occur on larger in size hard disk drives where vast volumes of information are placed. If a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it's more than likely that the damaged file will be treated as an ordinary one and it'll be duplicated on all of the drives, making the damage permanent. A huge number of the file systems that run on web servers today often are unable to locate corrupted files immediately or they need time-consuming system checks through which the server isn't functioning.

No Data Corruption & Data Integrity in Cloud Hosting

If you host your Internet sites in a cloud hosting account with our firm, you do not need to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform uses the advanced ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each file. Any kind of information that you upload will be kept in a RAID i.e. simultaneously on a number of SSD drives. A lot of file systems synchronize the files between the separate drives with this type of a setup, but there's no real guarantee that a file will not get corrupted. This could occur at the time of the writing process on each drive and after that a bad copy can be copied on the rest of the drives. What is different on our platform is that ZFS examines the checksums of all files on all of the drives right away and when a corrupted file is discovered, it is substituted with a good copy with the correct checksum from some other drive. That way, your data will stay undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't need to deal with any silent data corruption issues in case you buy one of our semi-dedicated server solutions since the ZFS file system that we employ on our cloud hosting platform uses checksums in order to ensure that all of 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. Because we store all content on a number of drives at the same time, the same file has the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives right away. If it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy right away, avoiding any chance of the corrupted copy to be synchronized on the other hard disks. ZFS is the only file system you can get which uses checksums, which makes it much more reliable than other file systems that cannot detect silent data corruption and duplicate bad files across drives.
