Optimizing Large File Backups
I recently migrated a client from networker tape backups to a our Avamar grid and am looking for a way to speed up the backup process.
When backing up the .bak files, about 200GB new data of the 1.4TB total, it takes about 8 hours to process. Is there a way to optimize the rate at which the files are backed up? When networker is performing the full backup, I see it reading the disk at at least 50MB/s as opposed to avamar crawling at ~10MB/s.
I would hate for the backups to fail overnight and then have to pick up 2 days worth of data for 16 hours. The major file in play is a new ~190GB bak created daily. we are using version 6.1.101-87

You can refer to Avamar 6.1 Operational Best Practices to tune performance.

You can use the file_cache (f_cache) option which is describes in the Operational Best Practice Guide.
