Subject  :  Generational copies for archiving
Size(KB) :  1


I archive certain data files into generations, thusly

rem * PIM files are archived every morning.
rem * Oldest archived folder is
SKW-15, delete it.
deltree %To%SKW-15
rem * Rename the second oldest folder to the oldest
name, etc.. Preserves create dates
move /-Y %To%SKW-14 %To%SKW-15
move /-Y %To%SKW-13 %To%SKW-14
move /-Y %To%SKW-12 %To%SKW-13
move /-Y %To%SKW-11 %To%SKW-12
move /-Y %To%SKW-10 %To%SKW-11
move /-Y %To%SKW-09 %To%SKW-10
move /-Y %To%SKW-08 %To%SKW-09
move /-Y %To%SKW-07 %To%SKW-08
move /-Y %To%SKW-06 %To%SKW-07
move /-Y %To%SKW-05 %To%SKW-06
move /-Y %To%SKW-04 %To%SKW-05
move /-Y %To%SKW-03 %To%SKW-04
move /-Y %To%SKW-02 %To%SKW-03
move /-Y %To%SKW-01 %To%SKW-02

rem * Always copy into the -01 folder.
It will have today's date.
echo Date of last backup > %From%SKW98\@FBU_date
rem * Above done to preserve a date
when the generations are copied to CDRW

xxcopy %From%SKW98\ %To%SKW-01\ /E /Y /R /C /H /EC /Q1

I have variants of this code for other folders that I run only
weekly or monthly.
In addition, daily, I xxcopy certain critical data folders into a
separate area, only newer files copied.
