To download a backup from an FTP site then delete the original …
C:pathcorecmd.exe -s -O -site site -d /path/latestbackup.bak -p c:ftp -delsrc -log c:logfile.log
-s = silent
-O = overwrite
-site = pre configured connection details within coreftp gui
-d = path to ftp site
-p = local destination
-delsrc = delete source after successful download
-log = record a logfile
******** UPDATE Dec 2012 ********
I found that this utility was the only way I could find to script/schedule FTPS uploads & downloads. Here’s more working examples …
“C:Program Files (x86)CoreFTPcorecmd.exe” -s -OS -site thirdpartyname -u “E:DBAthirdpartynamesomefilename_2012*.txt” -p “/export files/” -log E:DBAthirdpartynamelogfile.log
“C:Program Files (x86)CoreFTPcorecmd.exe” -s -OS -site thirdpartyname -d “/Client imports/somefilename_*.txt” -p \mylocalsqlserverdbathirdpartyname -log \mylocalsqlserverdbathirdpartynamelogfile.log
Note:-
– The use of double quotes so the utility isn’t confused by spaces in the path.
– The -OS switch which means copy everything except what’s already copied.
– The use of wild-cards with -OS to simplify management of file-names containing dates.
– the use of -u for uploading, and -d for downloads.
