What if, your server suffered an unexpected hard disk failure and the entire data on your server suddenly vanished? You frantically look for ways to recover the lost data, only to find that there are no backups available.

A single disk failure instance has turned out to be detrimental to your business. Data loss due to disk failures, human errors or virus attack can lead to business downtime and financial loss.

In spite of that, many business owners tend to overlook this risk and skip the backup process, leading to catastrophic events. For every business that depends on data availability, it is therefore very critical to safeguard and backup data. (more…)

One common failure point is network. Cloud systems comprise of a lot of sub-systems such as storage, backups, compute devices, etc. Each of these sub-systems talks to each other to perform critical functions such as creating new cloud instances, editing resource limits, etc. If there’s an issue with networks, servers wouldn’t be able to talk to each other, and cloud management functions will fail.

Each successful verification extends the validity of the license for a certain period of time (say 1 week), before which the system should check in again to keep everything working. (more…)

A website suddenly goes offline. The server is un-responsive. A server reboot is attempted, but the server fails to come back online.

This is typical of the way a server crash would unfold. As a server management company, we’ve often seen such issues with dedicated servers, however, recently we’ve started seeing such issues in cloud systems as well. People tend to associate cloud systems with stability, but even cloud system hardware and software are susceptible to failures.
