Accelerator Troubleshooting

Accelerator Troubleshooting

NetBackup Accelerator Challenge – Customers can’t complete their full backups within their backup window Solution – Significantly reduce time required for full backups of file systems Features – NetBackup client reads, de-duplicates and transfers only changes to media server and sends only metadata for changes to NetBackup catalog – Optimized synthetic full backup generated – NTFS change journal utilized to remove need to enumerate file system – Accelerator functionality supported with all client OS platforms (dedupe is performed on client, media server or appliance) 2

NetBackup Accelerator Realized Value – Full backups to NetBackup dedupe, Cloud or OSTvendor storage pools performed in similar amount of time as incremental backups – Reduced CPU and I/O overhead on NetBackup client

Accelerator – Overview Significant time reduction in performing full backups to file systems and VMware Align with existing deployments – – – – Leverage existing architectural framework & infrastructure Allow use of existing data protection management paradigm Seamless integration with existing NetBackup environment. Evolutionary approach to providing a new solution Reduce catalog data for full backups sent to Master Server Improve RTO and RPO Requires storage supporting Optimized Synthetics and Optimized Duplication, or Cloud 4
