Data corruption is the damage of data because of various software or hardware problems. When a file gets corrupted, it will no longer function correctly, so an application will not start or shall give errors, a text file shall be partially or completely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of info getting harmed without any acknowledgement by the system or an admin, which makes it a significant problem for web hosting servers as problems are more likely to occur on bigger hard disks where large volumes of information are placed. In case a drive is part of a RAID and the info on it is duplicated on other drives for redundancy, it is more than likely that the damaged file will be treated as a good one and will be copied on all of the drives, making the damage permanent. Lots of the file systems which run on web servers today often are unable to discover corrupted files immediately or they need time-consuming system checks through which the server is not working.
No Data Corruption & Data Integrity in Shared Website Hosting
In case you host your websites in a shared website hosting
account with our firm, you won't need to worry about any of your data ever getting corrupted. We can guarantee that because our cloud hosting platform employs the leading-edge ZFS file system. The aforementioned is the only file system which uses 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. Many file systems synchronize the files between the separate drives using such a setup, but there's no real warranty that a file won't get corrupted. This can happen throughout the writing process on each drive and then a damaged copy can be copied on the other drives. What is different on our platform is the fact that ZFS examines the checksums of all files on all of the drives immediately and in the event that a corrupted file is located, it's replaced with a good copy with the correct checksum from some other drive. By doing this, your info will continue to be undamaged 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 shielded from silent data corruption as all our storage servers use the reliable 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 will be placed on a couple of redundant drives operating in a RAID i.e. the files shall be the same on all drives. All the copies of a particular file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates right away, so if it identifies a mismatch, that will indicate that one of the copies is corrupted, it'll substitute that file with a good copy from one of the other disks. Even if there's an unforeseen power failure, the data on the servers won't be corrupted and there will not be any need for a time-consuming system check which other file systems perform following some malfunction, lengthening the time needed for the server to get back online. ZFS is the only file system which can really protect your content from silent data corruption.
