With what you have told us, the application could be a huge bottleneck, the application server could be a huge bottleneck, the database server could be a huge bottleneck, the database application could be a huge bottleneck, or any combination of the above could be a bottleneck.
Running a filesystem backup while running applications that are using files on that filesystem is VERY likely to affect performance of those applications and of the backup software.
We have seen examples in this forum of text processing code that invokes several processes to produce output for each line read from a file containing a few thousand lines that literally ran for more than 10 hours. When that code was replaced by a single awk script with the output fed into sort, the script ran in less than 10 seconds and produced exactly the same output. Could your application code have a similar issues?
To figure out where you need to look, you first need to know what are your major stumbling blocks. Are you swapping processes in and out a lot? (Need more memory?) Are your disks thrashing? (Put files on different filesystems on different disks/controllers?) Are your CPUs running at 100%? (Badly written code or too many users on your system?) Is your network dropping packets? (Loose connections, faulty routes to servers, failing hardware, etc.?) ... ... ...

ragator
RAGATOR(1) General Commands Manual RAGATOR(1)
NAME
ragator - aggregate argus(8) data file entries.
COPYRIGHT
Copyright (c) 2000-2003 QoSient. All rights reserved.
SYNOPSIS
ragator [-f ragator.conf] [raoptions]
DESCRIPTION
Ragator reads argus(8) data from an argus-file, and merges matching argus flow activity records together. In its default mode of options,
this effectively converts argus(8) files from detail to non-detail mode, and merges periodic flow report records to a single argus record,
thus compressing the argus(8) file to a reduced size.
You can modify the aggregation strategy used by ragator to merge records together, by using the -f ragator.conf option. See ragator(5) for
a complete description of the format and syntax of the flow model file.
OPTIONS
Ragator, like all ra based clients, supports a number of ra options including filtering of input argus records through a terminating filter
expression. See ra(1) for a complete description of ra options.
