Data corruption is the damage of info due to various software or hardware fails. After a file gets damaged, it will no longer work correctly, so an app will not start or will give errors, a text file could be partially or completely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an administrator, which makes it a significant problem for website hosting servers as fails are much more likely to occur on bigger hard drives where large volumes of info are placed. In case a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it is likely that the bad file will be treated as an undamaged one and will be copied on all of the drives, making the harm permanent. A lot of the file systems that run on web servers nowadays often are not able to discover corrupted files instantly or they need time-consuming system checks through which the server is not operational.
No Data Corruption & Data Integrity in Cloud Web Hosting
We warrant the integrity of the information uploaded in any cloud web hosting
account that is generated on our cloud platform since we use the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption thanks to a unique checksum for each file. We'll store your data on multiple SSD drives which work in a RAID, so the very same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all the files on all of the drives in real time and if the checksum of any file differs from what it needs to be, the file system replaces that file with a healthy copy from another drive from the RAID. There's no other file system which uses checksums, so it is easy for data to be silently damaged and the bad file to be reproduced on all drives over time, but since that can never happen on a server running ZFS, you don't have to worry about the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be shielded from silent data corruption since all of our storage servers make use of the advanced ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to ensure the integrity of each and every file. When you upload content to your account, it'll be stored on a couple of redundant drives employed in a RAID i.e. the files will be the same on all drives. All the copies of a given file will feature the same checksum on all drives and ZFS will compare the checksums of the copies right away, and if it discovers a mismatch, which would indicate that one of the copies is corrupted, it'll swap that file with a good copy from one of the other disks. Even if there's a sudden power loss, the data on the servers won't get corrupted and there won't be any need for a time-consuming system check which other file systems perform after some breakdown, lengthening 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.
