Change is a good thing. Unfortunately, when you are making big changes to your site or application, there is always room for error. Live-state snapshots takes the idea of a "backup" and takes it forward to its next logical step. Taking a snapshot of your partition not only creates a backup of your files, but also all of the processes running in the background at that instant in time. This way, if you make an error or break something while making updates, you can revert your partition to that exact snapshot, providing a working, fail-safe rollback.
When you read about VPS hosting, some questions naturally arise. Let's say, if there are multiple users on the same dedicated server, running virtual private servers, will they be able to access my data? That’s a valid question to raise, but in this case, we can happily inform you that you’re safe. All VPS hosting services are safely partitioned by specific software, which guarantees top-notch protection.
Unmetered hosting is generally offered with no limit on the amount of data-transferred on a fixed bandwidth line. Usually, unmetered hosting is offered with 10 Mbit/s, 100 Mbit/s or 1000 Mbit/s (with some as high as 10Gbit/s). This means that the customer is theoretically able to use ~3 TB on 10 Mbit/s or up to ~300 TB on a 1000 Mbit/s line per month, although in practice the values will be significantly less. In a virtual private server, this will be shared bandwidth and a fair usage policy should be involved. Unlimited hosting is also commonly marketed but generally limited by acceptable usage policies and terms of service. Offers of unlimited disk space and bandwidth are always false due to cost, carrier capacities and technological boundaries.
