What is the difference between multiplexing and "Allow multiple data streams"?
Hi everybody;
Maybe it was answered before but i am really wonder about this question:
What is the difference between multiplexing and "Allow multiple data streams"?
If i want to send a ndmp vo...
"I assume that i have 2 ndmp volume for example A and B in a policy and set to media multiplexing to 2. Does it mean that data for volume A and B start to write to tape at the same time?"
Yes, the policy would send upto 2 streams to a single drive, you would need multiple streams set also.
"And i assume that i have a one policy and it is including one ndmp volume. What if i want to backup this volume to 2 or more drives at the same time? What shouıld i set? "
I don't do much configuring of NDMP backups, but to multistream from one volume you would have to specify a lower level than the volume, eg. 'directory' level and specify these under new_stream in the policy file selection.
