Accelerator Troubleshooting. NetBackup Accelerator. 2. Challenge Customers can’t complete their full backups within their backup window Solution Significantly reduce time required for full backups of file systems Features
E N D
NetBackup Accelerator 2 • 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)
NetBackup Accelerator • Realized Value • Full backups to NetBackup dedupe, Cloud or OST-vendor storage pools performed in similar amount of time as incremental backups • Reduced CPU and I/O overhead on NetBackup client
Accelerator – Overview 4 • 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
Helpful processes and services The following processes or binaries are beneficial for troubleshooting: • NetBackup Backup Process: bpbkar • NetBackup Legacy Client Service: bpinetd • NetBackup Backup and Restore Manager: bpbrm • NetBackup Tape Manager: bptm • NetBackup Client Service: bpcd
