Server owners often encounter disasters in the form of hard drive crash or network failure. To safeguard their business, its crucial for hosting providers to minimize the calamities caused, mainly downtime and data loss.
In our role as Outsourced Tech Support for web hosting companies, we manage hundreds of cPanel servers for them. Configuring and managing fool-proof backups is a critical activity in our cPanel server management services.
Life is full of surprises. Some are unpleasant, like a server crash. Disk failures, human errors, external attack or natural calamities often lead to business downtime.
For businesses hosted on dedicated servers, recovering from a crash is tedious, as it often requires installing and configuring the physical servers afresh. (more…)
In IT systems, disaster can strike any moment and in any form. A hard disk failure, third party attack or even human errors can lead to data loss. To recover valuable data in such scenarios, backup management plays an inevitable role. But many times people just configure the backup once and leave it there. They assume that everything would just work fine when things go wrong.
Installing a backup software alone will not guarantee automatic recovery in case of data loss. Integrity check of the backups is also a very crucial aspect in backup management. This means verifying the backup for adequacy, completeness, accuracy and consistency. If the backup is not retrievable at the time of a disaster, that backup solution is of no use. (more…)
In our recent post ‘How to configure VM backups in oVirt‘, we saw how we configured a VM backup system for a cloud service provider. We further went ahead and expanded the backup system with oVirt engine backups.
oVirt engine manages the centralized configuration of the cloud system. This engine manages provisioning of VMs, connection protocols, user sessions, VM images, VM environment configuration, etc. It also provides a graphical interface to view, create and manage VMs. The engine configuration is saved in oVirt engine database and configuration files.
People often assume that backups are not important in a cloud setup due to its automatic fail-over feature. Automatic fail-overs migrate Virtual machines in a cloud from one hypervisor to another, when any one hypervisor goes down.
But this fail-over feature does not help in cases such as degradation of RAID arrays, server hacks, malware attacks or human errors, which can lead to accidental deletion or modification of data.
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…)
So, you have configured your server with backup. Thats great!
Most sysadmins are pretty confident about their backup systems, but is it really adequate? (more…)
