Best Practice for DFSR Backup of large data

Unfortunately, accelerator is the only way to speed up DFSR backup (if you have necessary license and matching storage types).

DFS-R has to be protected thru Shadow Copy Components:\User Data\Distributed File System Replication\ to avoid all backups being full. DFS-R backup are in general slow, that it the nature

My two cent:

• do not run backup of local drives (e.g C: D:)  and Shadow Copy Components:\User Data\Distributed File System Replication\ at the same time
• No more than 2 concurent streams stream below Shadow Copy Components:\User Data\Distributed File System Replication\
