Your pre-job script is trying perform all actions specified on your backup server, i.e. it tries to locate E:/Folder/Daily
on your backup server. Here are some advices:
1) It is no use keeping scripts on your target. Keep them on your backup server.
forfiles /p E:\Folder\Daily\ /s /m "*.doc" /c "cmd /c Ren @fname.doc *.olddoc" /d -03
In order to make your script work you'll have to either:
a) specify a UNC (\\TARGET_NAME\shared\folder\
) path to a shared folder instead of E:\Folder\Daily\
(don't forget about r/w permissions)
b) modify your script in such way that it starts some remote script/gets executed on a remote machine (psexec
can do the job).
However, I'd better stick to option "b" in order to eliminate the shared folder from the schema completely.
