SSIS variable for SQL Scheduled backup

Hi Experts,

I am working with SSIS to rename an SQL backup file.  The problem I am having is reading the most current file in the folder due to the format of the file name.  The current filename is: inetdispatchCAD_PEI_backup_2015_08_10_030001_3631355.bak.gpg.  This of course changes every backup, so i need to build an expression that will lookup the most current version of the files.  I will rename the file in order to decrypt it so that this inetdispatchCAD_PEI_backup_2015_08_10_030001_3631355.bak.gpg gets changed to this inetdispatchCAD_PEI_backup.bak.gpg.  Any help is greatly appreciated.

So Far I have this as a variable
"inetdispatchCAD_PEI_backup_" + (DT_WSTR,4)DATEPART("yyyy",GetDate()) + "_" +
RIGHT("0" + (DT_WSTR,2)DATEPART("mm",GetDate()) ,2) + "_" +
RIGHT("0" + (DT_WSTR,2)DATEPART("dd",GetDate()),2) + "_" +
RIGHT("0" + (DT_WSTR,2)DATEPART("HH",GetDate()),2) +
RIGHT("0" + (DT_WSTR,2)DATEPART("minute",GetDate()),2) +
RIGHT("0" + (DT_WSTR,2)DATEPART("ss",GetDate()),2) + "_" + ".bak" + ".gpg"

but it does not handle the ID of the file portion

I also tried following the instructions on this URL: http://www.devtechie.com/post/2012/08/22/Download-most-recent-file-from-FTP-using-SSIS.aspx

but I was still getting access denied errors
getmostrecentfile Error:the Remote server returned an error: (401) Unauthorized

i double checked the FTP address in the script, username and password...but It still does not work.

any ideas?

I can't tell from memory whether the ID is fixed for that DB. If it is, you can just add it as a constant. Else you should use a batch file to determine the most recent backup file - you should anyway, because your var cannot be correct. The current date and time won't match the backup at any time.

I ended up giving up on the FTP task within SSIS.  I used a powershell script to use winscp to get the most current file.  That works much better than the original track I was taking.  I was hoping to use all SSIS native tasks, but the powershell script was already written from the winscp site...so it was easy to implement.  Thanks for the idea
