Finding when a Exchange Store last backed up via script
" e* |; c* J* lThere are a couple of ways you can determine when the last time a particular exchange store was backed up if you're using a program that backs up via the Exchange Backup API (Veritas,Brightstore etc).

With Exchange 2003 a new function was added into System Manager to allow you to see the "Time of Last Full Backup" on the database tab. This property is also available in CDOEXM (if you have the 2003 version of system manager loaded on the machine). The ".LastFullBackupTime" property was added to the IMailStoreDB and IPublicStoreDB interfaces. Using this is pretty easy all you have to do is to open the mailstore using the LDAP DN path and access the property eg( z( ~& w" p, U
% t" m. Z7 V% g2 d9 n1 W) Q: Zset mdbobj = createobject("CDOEXM.MailboxStoreDB")
( a I9 `' M# r4 [0 y9 Emdbobj.datasource.open "LDAP://mbdDNpath" H, b8 N) }" r" `, H4 P' j
Wscript.echo "Last Backed Up : " & mdbobj.LastFullBackupTime9 W' Q- Y/ [$ x/ G) S! c0 \

I've put this together with a similar query from my previous post and this script selects all the exchange stores in a domain and reports when the last time they where backed up. I've posted the code here (this will on work on Exchange 2003)

4 t, H1 {8 \' yAnother method you can use to do this is to query the eventlog on each of your servers and look for each of the 221 completion events for each of the database files. When the backup runs on a Exchange server you get a bunch of really useful events that tell you when the backup started, how much was backed up and when it finished. In this script im focusing on the finished events which include the path to the database file. So if I combine it with the script from my previous post which was already getting the server name and file path of each of the database files. You end up with a script that will query Active directory for every mail and public folder store then query the event log via WMI to work out when the last time a backup occurred of each file and display the result on the commandline. Note I've limited the search range to the last 7 days so if a server hasn't backed up in the last 7 days you receive a no backup recorded message. This was done to keep the time it takes to run the script to a minumn as searching through a really large event log can be very time consuming. I've posted a copy of the script here The code look like: v& H. l3 C) ~5 c
