Hi Team, I am currently evaluating exchange 2010 restore. Performed the following test: 1.Installed Exchange 2010 2.Created a mailbox database 3.Created a user and populated with 10 emails 4.Performed a backup of this database 5.Deleted 5 emails permanently. 6.Now ran a database restore 7.Upon restore i only see 5 emails in the user mailbox and not 10. 8.I closed and re-opened OWA again but same problem observed. 9.I later deleted the database files and submitted a restore of database. 10.Upon restore now all the 10 emails are seen. Could anyone let me know the root reason why i am unable to see all the emails upon step (6) and how i can get back all the emails? Thanks Senthil

Hello, I have used Windows server backup several times and didn't had a problem. So please let us know which software you have been used? Also why you used Database restore, Exchange 2010 has DAG, Dumpster 2.0 and lagged copies now. See below Article.

Hi Chinthaka, I am using ARCserve Backup to backup and restore database.Also aware of DAG feature in exchange and other tools to retrieve email.But i would like to know why the deleted 5 mails are not back into the mailbox on performing database restore overwriting the database files.I observed the same problem in ntbackup utility as well on exchange 2003 server. Thanks Senthil

Hi, There is no any known problem regarding exchange 2010 backup and recovery. Can you try with Windows Server Backup whether can be restore all emails? Regards Chinthaka Shameera | MCITP: EA | MCSE: M | http://howtoexchange.wordpress.com/

If you restored without deleting the log files, after the restore the log files would have played and deleted the messages. -- Ed Crowley MVP "There are seldom good technological solutions to behavioral problems." .

Hi Ed, Thanks for the update.Could you please help me to understand why replaying the log files deleted those email items? Senthil

Under the scenario I described, the log files contained "delete" transactions. Say you took the backup at 01:00. User deletes mail at 08:00. Backed-up store contains the messages as they have not been deleted yet, however, transaction logs still on the server have "delete" transactions from 08:00. So when you restore at 17:00, the restored database still has the items that were deleted, but when the transaction logs replay the 08:00 "delete" transactions cause the messages to be deleted. -- Ed Crowley MVP "There are seldom good technological solutions to behavioral problems." .
