Or perhaps this way.
Get list of backups for this node (mccli backup show --name=/this-node --after=last-two-weeks)
For each label #
Check the backup for file in the directory of interest
(mccli backup show --name=this-node --after=last-two-weeks --labelNum=label# --dir=/directory-of-interest)
if files are found, look for the most recent DB2 backup file
if backup found, restore it
mccli backup restore --name= -labelNum= -data=full-path-to-file
