if the fle system becomes inconsis-tent or corrupted, recovery data is lost this is why we back up data in the frst placean effective disk-based data protection solution requires enterprise-level backup and recovery software that takes advantage of disk as a random access device and a robust, reliable storage system to make deep retention and network vaulting economically and operationally feasible at the same time, the solution must ensure improved reliability and data integrityFocuscd on Rccovcry: CommvaulI 0alaxy and 0aIa 0oman the purpose of backups is to recover although a backup process may complete successfully, the result-ing backup image is useless if users cant get back the information they need recovery operations must work reliably, quickly and effciently the combination of commvault Galaxy and data domain systems provides a cost-effective, powerful disk-based data protection solution, focused on the integrity and reliability of data recovery the com-bined solution delivers:increased backup and recovery performanceSimultaneous backup, recovery, and auxiliary copy processes for more fexible data protectiondeduplication storage to retain months of recovery images at the cost of tapeCommvaulI 0alaxy 8ackup and Rccovcry wIh 0aIa 0oman0 A J A 0 0 MA I N I F n I c r p r s c P r o I c c I o n S I o r a g c5network-effcient Wan vaulting for more responsive dr protectionHighly reliable, proactive verifcation of data recoverabilityoptimized for naS and San environments through network data management Protocol (ndmP) and virtual tape library (vtl) supportHigh availability backup and recovery infrastructureCommvaulI 0alaxy 8ackup and Rccovcry commvault Galaxy backup and recovery software is a proven enterprise solution to protect and increase data availability it focuses on business resumption, not just data backup By tightly integrating with busi-ness-critical applications such as microsoft Exchange, Galaxy ensures data consistencycommvault Galaxy has been supporting disk as a backup target for over a decade it is designed to take full advantage of the random access capabilities of disk it supports simultaneous backups, restores, and copies (auxiliary copy) leveraging native fle systems on disk and its two-part indexing scheme, Galaxy software optimizes backups to disk unlike competing solutions that treat disk as a sequential device0aIa 0oman Applanccs and Arraysdata domain systems are specialized disk-based data recovery appliances and arrays designed for high throughput backup and recovery processes and highly reliable recoveries With its revolutionary deduplication technology and data invulnerability architecture, it provides unprecedented levels of data protection, data verifcation, and self-healing capabilities that are unavailable in conventional disk or tape systemsdata domain systems easily and seamlessly integrate with existing commvault Galaxy environments as nfS or cifS fle servers or as a vtldata domains deduplication technology, Global compression, dramatically reduces the storage capacity required for commvault Galaxys backup data key benefts of Global compression include:less than $35/GB for disk-based backups99% bandwidth reduction for Wan vaulting or remote offce data protection20x storage reduction for retaining months of backup dataCommvaulI 0alaxy 8ackup and Rccovcry wIh 0aIa 0oman0 A J A 0 0 MA I N I F n I c r p r s c P r o I c c I o n S I o r a g c6CommvaulI 0alaxy and 0aIa 0oman aI Workthis section highlights the following confgurations with commvault Galaxy and data domain systems:data domain systems as backup targets either Galaxys magnetic library or tape library devicesGalaxys auxiliary copy for creating tape copies from a data domain system for long-term archival or offsite tape vaulting purposesBandwidth effcient network vaulting using data domain replicator0aIa 0oman SysIcms as a CommvaulI 0alaxy 8ackup JargcIdata domain systems are specially designed to be simple and intuitive to install, confgure, and integrate into commvault Galaxy environments data domain systems appear as naS appliances supporting nfS or cifS over Gigabit Ethernet or as an emulated vtl over fibre channel using the commvault mediaagents, the systems are simply added as a magnetic library or tape library device as magnetic library devices, when multiple systems are used, backup data can automatically span several mount points Similar to media spanning on tape, Galaxy also allows backup to disk jobs to span from one fle system to another without user intervention or job disruption, simplifying management CommvaulI Auxlary Copy Ior CrcaIng Japc Copcs Ior Long-Jcrm Archvalthe confguration in Site a provides a solution for creating tape copies from a data domain system when dr or data retention requirements mandate the use of removable media a tape library and the system are attached to the mediaagent the system s
