Resource consumption file backup job option explanation (DataCenter 8.2.x and newer):
The usage of resources for file backups can now be configured to achieve better performance, this option was added in DataCenter 8.2.1. The option is only available for file backup jobs. New file backup jobs default to medium level. If you upgrade the version then the resource consumption option that was configured prior will be maintained. If you create a file backup job in a version that did not contain the Resource consumption option then it will not be enabled and you will need to enable and configure the setting in order to make use of it.

Resource consumption option explanation (the default level for a new job is medium):
Level |
Number of Read Threads |
Read Buffer |
RAM Allocation |
low |
Cores |
8M |
512M |
medium |
Cores*2 |
16M |
1024M |
high |
Cores*4 |
32M |
2048M |
highest |
Cores*8 |
64M |
4096M |
So, if you want maximum load on the system use 16 Splits and the highest resource consumption.
BTW: Of course, we will never try to allocate more RAM than actually available. We will at maximum consume ¾ of the available memory.
