Data corruption is the damage of info caused by various software or hardware failures. Once a file is damaged, it will no longer work as it should, so an application 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 info getting damaged without any acknowledgement by the system or an admin, which makes it a serious problem for web hosting servers as problems are much more likely to occur on bigger hard disks where vast volumes of info are located. In case a drive is a part of a RAID and the data on it is copied on other drives for redundancy, it is very likely that the damaged file will be treated as a good one and will be duplicated on all the drives, making the damage permanent. A lot of the file systems that operate on web servers nowadays often cannot discover corrupted files in real time or they need time-consuming system checks through which the server is not operational.
No Data Corruption & Data Integrity in Website Hosting
In case you host your Internet sites in a website hosting
account with our firm, you do not need to worry about any of your data ever getting damaged. We can guarantee that since our cloud hosting platform works with the leading-edge ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each file. Any kind of info that you upload will be saved in a RAID i.e. simultaneously on many SSDs. A lot of file systems synchronize the files between the separate drives using such a setup, but there is no real warranty that a file won't get corrupted. This may occur throughout the writing process on any drive and afterwards a corrupted copy can be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all of the drives live and when a corrupted file is located, it's substituted with a good copy with the correct checksum from another drive. By doing this, your data will remain unharmed no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be protected against silent data corruption since all our storage servers use the reliable ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, to verify the integrity of each file. When you upload content to your account, it'll be placed on several redundant drives operating in a RAID i.e. the files shall be the same across all disks. All the copies of a particular file will have the same checksum on all drives and ZFS will compare the checksums of the copies right away, so if it identifies a mismatch, which will indicate that one of the copies is damaged, it will replace that file with a healthy copy from one of the other disks. Even if there is an unforeseen blackout, the data on the servers won't be corrupted and there will not be any need for a time-consuming system check that other file systems perform after some breakdown, extending the time needed for the server to return online. ZFS is the file system which can truly protect your content from silent data corruption.
