No Data Corruption & Data Integrity
See what No Data Corruption & Data Integrity is and how it can be good for the files inside your web hosting account.
The process of files being damaged as a result of some hardware or software failure is called data corruption and this is one of the main problems which hosting companies face as the larger a hard drive is and the more information is stored on it, the much more likely it is for data to be corrupted. There are a couple of fail-safes, still often the information becomes damaged silently, so neither the particular file system, nor the administrators see anything. Because of this, a corrupted file will be handled as a good one and if the HDD is part of a RAID, the file will be copied on all other disk drives. Theoretically, this is done for redundancy, but in reality the damage will be worse. Once a file gets damaged, it will be partly or entirely unreadable, therefore a text file will no longer be readable, an image file will present a random mix of colors if it opens at all and an archive will be impossible to unpack, so you risk sacrificing your content. Although the most widely used server file systems include various checks, they often fail to discover a problem early enough or require a vast time period to be able to check all files and the server will not be operational for the time being.
No Data Corruption & Data Integrity in Cloud Hosting
We guarantee the integrity of the info uploaded in each and every cloud hosting
account which is generated on our cloud platform as we work with the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption thanks to a unique checksum for every single file. We shall store your info on a large number of SSD drives which work in a RAID, so the exact same files will be accessible on several places concurrently. ZFS checks the digital fingerprint of all files on all the drives in real time and if the checksum of any file is different from what it needs to be, the file system replaces that file with an undamaged copy from another drive within the RAID. No other file system uses checksums, so it is possible for data to be silently damaged and the bad file to be replicated on all drives over time, but since this can never happen on a server using ZFS, you won't have to worry about the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you obtain one of our semi-dedicated server
solutions, you will not have to worry about silent file corruption since we use ZFS - a high level file system which checks all the files in real time. Whenever you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between a couple of SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all of the copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done instantly, so there will be no danger for any part of your content at any moment. By comparison, all of the other file systems perform checks after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a bad copy could be replicated on the other drives as well and you can lose precious data. Since this is not the case with ZFS, we can guarantee the integrity of each file you upload no matter what.
