Data corruption is the unintended modification of a file or the loss of info which usually occurs during reading or writing. The reason can be hardware or software failure, and due to this fact, a file can become partially or fully corrupted, so it'll no longer work correctly because its bits shall be scrambled or lost. An image file, for example, will no longer display an actual image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. In case this kind of a problem occurs and it isn't identified by the system or by an administrator, the data will get corrupted silently and if this happens on a disk drive that is a part of a RAID array where the data is synchronized between various different drives, the corrupted file shall be replicated on all of the other drives and the harm will be long term. A number of popular file systems either don't have real-time checks or do not have good ones that will detect a problem before the damage is done, so silent data corruption is a common problem on hosting servers where large amounts of data are stored.
No Data Corruption & Data Integrity in Website Hosting
We warrant the integrity of the information uploaded in every single website hosting
account which is created on our cloud platform as we employ the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption via a unique checksum for each file. We'll store your data on multiple SSD drives that work in a RAID, so the exact same files will exist on several places simultaneously. ZFS checks the digital fingerprint of all files on all the drives in real time and in the event that the checksum of any file differs from what it has to be, the file system swaps that file with a healthy version from some other drive within the RAID. There's no other file system that uses checksums, so it's possible for data to be silently corrupted and the bad file to be replicated on all drives over time, but since this can never happen on a server running ZFS, you won't have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not need to deal with any silent data corruption issues whatsoever if you obtain one of our semi-dedicated hosting
packages because the ZFS file system that we use on our cloud hosting platform uses checksums to make sure that all of the files are undamaged all of the time. A checksum is a unique digital fingerprint which is allotted to each and every file stored on a server. Due to the fact that we store all content on a number of drives simultaneously, the same file uses the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. In case it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy right away, avoiding any possibility of the damaged copy to be synchronized on the remaining hard drives. ZFS is the sole file system out there which uses checksums, which makes it much more reliable than other file systems that are not able to detect silent data corruption and duplicate bad files across drives.
