Lustre backup and recovery

Wednesday, August 27th, 2008

Lustre is a scalable, secure, robust, and highly-available cluster file system. Lustre has multiple components: Meta data servers, Object storage servers and Lustre clients.

Amanda can be used for backup and recovery of Lustre file systems as well as for disaster recovery of Lustre Meta data servers and Object storage servers. A white paper on how to use Amanda with Lustre file system is available here.

Accelerate Amanda Backups with Hardware Boards

Tuesday, September 11th, 2007

Amanda Enterprise uses plug-in model to enable different compression and encryption methods for backing up data. Amanda’s flexible configuration allows users to match compression/encryption method to the data being backed up. Compression of backup images reduces the network bandwidth as well as backup media space requirement. Backup encryption is essential for security of backup images.

Hardware compression and encryption cards provide significant advantages compared to software methods. Software methods use lot of CPU resources in the server or client depending on where the compression/encryption is performed. The hardware acceleration cards make the backups faster with a reduction in use of CPU resources.

Indra Networks, a leading developer of hardware accelerator cards for data compression and encryption, have integrated Amanda Enterprise with their hardware accelerator boards. A white paper describing how to use Amanda enterprise with hardware compression and encryption cards is available in Zmanda Network. The paper also provides backup performance measurements with the hardware acceleration cards.
