Hi
You could first discard the CDBACKUPFILE string by using a substring command based on the length of this first parameter.
Then use a filter to remove any number from your string, or alternatively a substring command if your seq number has a fixed length.
I don't give you the code as I don't have the time to test it
I just hope this will indicate you how to do the job.

memmem - locate a substring SYNOPSIS
#define _GNU_SOURCE /* See feature_test_macros(7) */ #include <string.h> void *memmem(const void *haystack, size_t haystacklen, const void *needle, size_t needlelen); DESCRIPTION
The memmem() function finds the start of the first occurrence of the substring needle of length needlelen in the memory area haystack of length haystacklen. RETURN VALUE
The memmem() function returns a pointer to the beginning of the substring, or NULL if the substring is not found. ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7). +----------+---------------+---------+ |Interface | Attribute | Value | +----------+---------------+---------+ |memmem() | Thread safety | MT-Safe | +----------+---------------+---------+ CONFORMING TO
This function is not specified in POSIX.1, but is present on a number of other systems. BUGS
In glibc 2.0, if needle is empty, memmem() returns a pointer to the last byte of haystack. This is fixed in glibc 2.1. SEE ALSO
