There are two ways that you can recover Exchange data. You can firstly restore the complete Information Store. This will over write any existing information. Alternatively, you can restore a recovery mail store and then merge or copy the data into the active Exchange information store. The procedures below out line how to complete both of these options when using Arcserve software to restore your Exchange information. To Restore the complete Exchange Information Store 1. Ensure that Exchange services are running. You can do this from Services in the Administration Tools. 2. Open the Exchange System Manager via Start All Programs Microsoft Exchange System Manager. 3. In Exchange System Manager navigate to Servers <Servername> First Storage Group. Underneath this folder you should see Mailbox store (SERVER) and Public Folder Store (SERVER)

2 4. Dismount both stores. Right mouse click on Mailbox store (SERVER) and select Dismount store. Repeat the process with the Public Folder Store (SERVER). You can tell whether the mail store is dismounted by the fact it has a small red icon over the picture for the store name.

3 5. Right mouse click on the Mailbox store (SERVER) again and select Properties. 6. Select the Database Tab 7. Check the option This Database can be overwritten by a restore

8 3. In Exchange System Manager navigate to Servers <Servername>. Right mouse click on <Servername> and Select New Recovery Storage Group. 4. Set the location of the recovery storage group. Ensure that you allow enough space for the entire store to be recovered. This means that during the process a copy of the entire information store will be installed in the location you specify here. Thus, you will have 2 copies of your Exchange Information Store on your server.

9 5. You should now see a item called Recovery Storage Group listed in the Exchange System Manager tree. Right mouse click on this and select Add Database to recover.

10 6. You will be presented with a list of Mailbox stores that you can recover. For SBS systems only one should appear, select it and hit OK.

Select the green square to the left of this name to make this the source of the restore. Once this is selected in the right hand window you should see two items as being selected : Mailbox Store (SERVER) and Public Folder Store (SERVER). Click the green square to the right of Public Folder Store to unselect restoring the Exchange public folders. If you do not unselect this the restore process will fail and you will be unable to mount the recovery store.

14 11. On the destination tab uncheck the option Restore files to their original location(s) 12. Select Windows NT/2000/XP/2003 Systems Server Microsoft Exchange Server Database Level(IS). Ensure this is highlighted as your destination. Arcserve will not display the Recovery store as potential destination. As long as the Recovery store exists Arcserve will automatically restore the Exchange Information store here.

15 13. Press the Start button on the Arcserve toolbar to commence the restore process. Ensure that the restore procedure completes without errors.

16 14. Locate the directory where you restored the Recovery Group and ensure that it has files in it. Normally this will be something like : e:\program files\exchsrvr\recovery storage group. 15. If the option to automatically mount Recovery Storage Group was not selected then return to Exchange System Manager and locate the dismounted Mailbox store under the Recovery Storage Group. Right mouse click the store and select Mount Store. 16. You will now see a message warning you not to mount the Recovery Storage Group until after you have restored the Exchange data. Since this has already been completed we can ignore this warning and press Yes to continue.

17 17. You should receive a message telling you that the store was successfully mounted.

18 18. If you are not using Exchange 2003 Service Pack 1 you will need to use the Exmerge utility to extract and import mailboxes between the Recovery Store and the normal Mailbox store. 19. If you are using Exchange 2003 Service Pack 1 you can recover mailboxes directly from the Exchange System Manager. 20. To use the Exchange System Manager to recover boxes locate the mailbox folder under Recovery Storage Group Mailbox Store (SERVER) and select it. On the right you should see a list of all the mailboxes in your Exchange with a red cross through them indicating they are not connected. To recover an box simply right mouse click on a user box and select Exchange Tasks. You will not be able to recover and Exchange mail box unless you have administrator rights on the normal Exchange mail store. You can determine these securities by right mouse clicking on Mailbox Store ( SERVER) and selecting Security.

19 21. Once the Exchange Tasks Wizard has started select Next. On the next screen the only item that should be available is Recover Mailbox Data. Ensure this is selected and press Next.

20 22. The destination mailbox store is show, click Next to continue.

21 23. You can now choose whether you wish to Merge the Data into the existing mailbox ( this will merge data with what already exists in the users mailbox ). You can also choose to Copy Data into the users mailbox ( this will recover data into a folder in the user s current mailbox ). Once you have made your preferred option select the Next button.

22 24. You can select when you wish the merging to commence ( immediately by default ). You can optionally specify when to stop the merging process ( to prevent the merge hanging or running during production hours ). Beware that the time required to restore the data to the original mailbox may take quite a while depending on the size of the mailbox. Typically, to restore a mailbox that is 1 GB in size should take just over 60 minutes to restore.

24 25. When you have completed restoring the mailbox data you should delete the Exchange Recovery Storage Group to free up disk space. To delete, highlight the Mailbox Store under the Recovery Storage Group ( not the Mailbox store under the First Storage Group which is your live Exchange Data ) and press the delete key. Check you are deleting the correct Mailbox store and press Yes. You will be prompted with a message about manually deleting database file, press OK to proceed.

25 26. There should now be nothing under the Recovery Storage Group. To delete the Recovery Storage Group simply select it in Exchange System Manager and press the Delete key. When prompted, select Yes to remove the Group. Once deleted the Recovery Group should no longer appear in Exchange System Manager. 27. Locate the location of the Recovery Storage Group on your machine using Windows Explorer. It will typically be in a directory like..\program files\exchsrvr\recovery storage group. 28. To remove the files from your server simply delete them using Windows Explorer. Due to size of these database files it is probably a good idea to erase them completely rather than sending them to the recycle bin.
