Data corruption is the damage of information due to various hardware or software failures. When a file is damaged, it will no longer function as it should, so an app 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 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 hosting servers as problems are much more likely to occur on larger hard disk drives where significant volumes of info are located. When a drive is a part of a RAID and the information on it is replicated on other drives for redundancy, it's very likely that the damaged file will be treated as a standard one and will be copied on all of the drives, making the damage permanent. Lots of the file systems which operate on web servers today often cannot detect corrupted files immediately or they need time-consuming system checks through which the server is not functioning.

No Data Corruption & Data Integrity in Cloud Hosting

If you host your websites in a cloud hosting account with our company, you will not need to worry about your data ever getting damaged. We can guarantee that as our cloud hosting platform works with the cutting-edge ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each file. All the data that you upload will be kept in a RAID i.e. simultaneously on a number of SSDs. A lot of file systems synchronize the files between the different drives using this kind of a setup, but there's no real warranty that a file will not be corrupted. This could happen throughout the writing process on each drive and after that a bad copy may be copied on all other drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all drives in real time and when a corrupted file is identified, it's substituted with a good copy with the correct checksum from another drive. In this way, your information will stay unharmed no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not have to deal with any silent data corruption issues if you get one of our semi-dedicated server packages due to the fact that the ZFS file system that we employ on our cloud hosting platform uses checksums in order to ensure that all the files are undamaged at all times. A checksum is a unique digital fingerprint which is assigned to each and every file stored on a server. Due to the fact that we store all content on a number of drives simultaneously, the same file has the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives in real time. In the event that 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 possibility of the damaged copy to be synchronized on the remaining drives. ZFS is the only file system out there which uses checksums, which makes it much more reliable than other file systems that are not able to identify silent data corruption and duplicate bad files across drives.
