Dedup strategy
Hi
I am setting up a new BE 2014 envt and using the BE dedup option with HP MSA as disk storage.
Since I am backing up VMs (using API) which are a mix of Linux and Windows does it make sense to have 2 diff disk libraries one as target, 1 for Linux VMs and other for Windows ?
Will this give better dedup ratio than having a single disk library for both VMs ?
Also I have couple of phsyical Wndows servers which have DBs running on it. Any suggestions on what config will give me the best dedup ratio.
3 diff disk library (1 each for Windows VM. Linux VM, phyiscal servers )?? or have all of them point to a single disk library ?
Thanks in advance.
Hi,
You can only have 1 dedupe target per media server. Just split the backups off from each other (LInux/Windows).Read up on the BE 2014/15 dedupe best practices here:

THanks!
1) Keep Linux and Windows VM Backup in seperate Jobs since Linux we do not support GRT backup with Agent for Vmware Virtual Infrastructure
Eg :
File Server Backups - Use AVVI Backup with File Folder GRT enabled
Application Server like exchange, SQL., AD - Use AVVI with File Folder and Application GRT
Linux VMs - Use Agent Backup or AVVI Backup whichever suits your Backup and Restore strategy. With Agent you can perform individual file restores easily else with AVVI Backup of Linux you will have to restore the entire VM to get that 1 file. So depends which one you choose for Linux VM backup.
2) The way you perform AVVI Backups to normal storage is the same as you would do AVVI or any other backups to Deduplication Storage.
Note : Backup Exec has stream handler which easily understand which part of vmdk has changed and hence provides better dedupe ratio. This works when GRT is enabled for the Backup of VM using AVVI.
