>From the disklist(5) manpage, an DLE has this format:
hostname diskname [diskdevice] dumptype [spindle [interface] ]
Your dumptype is in {...}, so the numbere "1" is a spindle number
and is optional. Spindle number is later defined as:
spindle
Default: -1. A number used to balance backup load on a host. Amanda
will not run multiple backups at the same time on the same spindle,
unless the spindle number is -1, which means there is no spindle
restriction.
As all of the rcav-fs01, E:/... DLEs are on the same spindle, they
should all have the same, arbitrary, spindle number. Unless you
don't care if several might be dumped at the same time (with the
attendant load on the disk and network).
As to your DLE definition, I don't see anything I'm certain is
wrong. Two things that are unusual and you can try but I don't
hold out much hope.
1. E:/SERVER_DATA/./a is the "diskname", it is not a path. I'm
not used to seeing slashes in the diskname unless it is also the
device name. So something like SERVER_DATA_a or E_ServerData_a
could be used.
But, I don't think slashes are illegal in disknames.
2. In filename matching expressions, square brackets ([...])
define a character class, typically a set with multiple members
such as [abcd] or [a-d]. When the set has only one member the
brackets are superfluous. At least they should be.

I took a peek at the above ZWC document and noted two points:
It says exclude is supported but does not mention include.
The exclude examples use backslashes rather than slashes
and say they must be doubled up or use no slashes.
Depending on the naming consistency of your SERVER_DATA
directory, perhaps your include could be an exclude:
exclude "[A-Zb-z]*"
A potential problem might be files or directorys starting
with non-alphabetic characters.
