Deleting geodatabases that are more than one week old?

Question

I am using ArcGIS Desktop 10.0 and Python 2.6.6 and am trying to make an update script to copy the geodatabase to a backup folder with the date as part of the name, got that to work.

Then export features from my editing geodatabase to the one on our server, got that working.

But now I want to, at the end of my script, to go back to the backup folder and delete any geodatabases there that are older than 1 week to keep it clean.

Tried a number of ways but they didn't work, any suggestions?

import re
import os
import datetime
import time
import sys

from subprocess import call

now = time.time()
cutoff = now - (7 * 86400)

files = os.listdir("C:\GIS Info\Test\Backup")
for xfile in files:
        if os.path.isfile( "C:\GIS Info\Test\Backup" + xfile ):
                t = os.stat( "C:\GIS Info\Test\Backup" + xfile )
                c = t.st_ctime

                # delete file if older than a week
                if c < cutoff:
                        os.remove("C:\GIS Info\Test\Backup" + xfile)

This is the code I was trying to use that got me the furthest.

Since FGDB's are treated as folders, this script looks for folders in a directory older that seven days, then uses the Delete management tool to remove the old folders.

import os
import time
import arcpy

dirPath = r"C:\test_data"
cutoff =  7 * 86400
present = time.time()
directories = []
for root, dirs, files in os.walk(dirPath, topdown=False):
    for name in dirs:
        subDirPath = os.path.join(root, name)
        if (present - os.path.getmtime(subDirPath)) > cutoff:
            directories.append(subDirPath)

for gdb in directories:
    arcpy.Delete_management(gdb)

It doesn't work only on GDB's, it deletes all sub directories older that seven days. But you could tweak it to only delete GDB's and leave other directories in place.
