In our enviroment we use 20 cache x 1 TB each one (on CX) to perform backup to disk.
For the stage policy the LowWatermark is 60% and the HighWatermark is 70%.
Using 10 LTO 3 device the performarce are very poor (14 MB/s).
Sometime the backup server (732_build 399 in cluster configuration) work only for staging job and all backup groups are in waiting for many time.
Anybody knows if there is a "best practics" for cache dimension or policy ?
I think that this cache are very big .
Thank
Gianluca
