This is a list of 10 open source backup and recovery tools that the author believes are the most useful. We suggest that the reader tries out a few of them.

Backup and recovery are integral part of any datacenter these days. With the current data explosion, the need for an efficient backup/recovery solution has become critical.
The open source world offers its own solutions in this space and provides data archiving/backup solutions for efficient performance, while ensuring cost savings.

How open source tools help a data centre
Open source tools have many advantages in the data centre environment. First and foremost is their low cost and the flexibility they provide. Also, being open source, everyone will be aware of the source code so any enhancements that need to be done have a greater chance of getting implemented, quickly.
Most open source projects have a lot of contributors. And being FOSS, systems administrators can always customise the code to suit their data centre needs.

Ten FOSS backup tools
1. AMANDA
AMANDA stands for Advanced Maryland Automatic Network Disk Archiver. It is a simple backup solution that allows the IT administrator to set up a single master backup server to back up multiple hosts over the network to media, which could range from tapes to hard disk drives.
AMANDA uses native utilities and formats and can back up a large number of servers and workstations running multiple versions of Linux or UNIX. It uses a native Windows client to back up Microsoft Windows desktops and servers.

4. Clonezilla
Clonezilla is a partition and disk cloning program, as the name suggests. It is similar to many varieties of ghost software available in the market. It helps you to do systems deployment, bare metal backup and recovery.
One of the main advantages of Clonezilla is that it can be used in large environments to recover multiple systems from bare metal, simultaneously.

Managing disaster recovery
Disaster recovery or DR is the process by which we can recover and protect IT infrastructure in the event of a disaster. As data is getting more and more important by the day, DR plays a vital role in keeping businesses running. So how can an IT administrator avoid downtime and bring a business back into action after a disaster? This requires methodical planning, testing of the solutions that are being used in a data centre, and then implementation.
A lot of DR methods are now available, ranging from tape archive backups, replication and cloud backups.
