Hi, Can we achieve this separate pool configuration, or multiple device storage in BACULA ENTERPRISE without any performance issues.
I want maximum throughput may be for a 3000 vm's and each vm should have their backup separated. They must be able to see their individual backups and do what ever they want.

Hello, There is no limitation on the number of Pools in Bacula, but the code was written assuming a relatively small number of Pools (probably less than say 10,000). Consequently when you use more Pools, you may find at some point, probably well beyond what you are planning, that the Pool access algorithms need to be adjusted. This was for example a problem with having a huge number of Jobs (e.g. more than several thousand). For Jobs, I rewrote the algorithms for accessing Job resources a number of years ago, which essentially eliminates the performance problems with the old linear algorithms.
