Hi,
I'm hoping someone can explain why if I set the 'number of data readers' on a subclient to 3 or 4 the backup speed is extremely slow (7GB/hr).
However if I set the data readers to 1 the speed is much quicker (30GB/hr) although not as quick.
I would have thought that with multiple data readers, the read speed from the source would be faster, considering the source volume is a SAN volume.
The Magnetic Library on the Media Agent has multiple data paths all set to 5 writers as allocation policy.
The Storage Policy has Device Streams set to 5.
Appreciate if someone could help explain this.
thanks
