Data corruption is the damage of data caused by various hardware or software problems. After a file is damaged, it will no longer work properly, so an application will not start or shall give errors, a text file could be partially or completely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an admin, which makes it a serious problem for web hosting servers as problems are more likely to occur on bigger hard disk drives where significant volumes of information are placed. In case a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it's very likely that the bad file will be treated as a regular one and it will be copied on all the drives, making the harm permanent. A huge number of the file systems which run on web servers nowadays often are unable to locate corrupted files immediately or they need time-consuming system checks through which the server is not working.
No Data Corruption & Data Integrity in Hosting
If you host your Internet sites in a hosting
account from our firm, you don't need to worry about your data ever getting corrupted. We can ensure that due to the fact that our cloud hosting platform employs the cutting-edge ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each and every file. Any information that you upload will be stored in a RAID i.e. simultaneously on a large number of SSDs. All the file systems synchronize the files between the separate drives with this kind of a setup, but there is no real guarantee that a file will not be corrupted. This may occur throughout the writing process on each drive and then a damaged copy may be copied on the other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all of the drives right away and in the event that a corrupted file is identified, it is replaced with a good copy with the correct checksum from another drive. This way, your info will remain undamaged no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be protected against silent data corruption as all of our storage servers use the innovative 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 a couple of redundant drives working in a RAID i.e. the files shall be the same on all disk drives. All of the copies of a particular file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies quickly, and if it detects a mismatch, which will indicate that one of the copies is damaged, it will replace that file with a good copy from one of the other disks. Even if there is an unforeseen blackout, the data on the servers will not become corrupted and there won't be any need for a time-consuming system check which other file systems perform after some malfunction, prolonging the time needed for the server to return online. ZFS is the sole file system that can really protect your content from silent data corruption.
