Restoring from MS-Backup of exchange. Deleted e-mail messages not being restored.
Posted on 2006-11-27
I'm trying to restore some e-mail messages I deleted. Its no big deal if I cannot retrieve these, but I am concerned for other situations. Here is some background:
The server is MS-Exchange 2003 (6.5.7638.1). The client an Outlook 2003 sp2 client. The mail is delivered to the exchange mailbox. Mail has been delivered OK for months. I have a nightly procedure that uses NTBackup to save the exchange Information store.
I discovered some a missing Outlook folder. I attempted to restore from the NTBackup I made about a week ago. I:
- Made a temporary NTBackup of the Exchange Server's Microsoft Information Store.
- Signed on to users and Exported their mailboxes to disk (I just dont trust MS).
- Dismounted the Server's Mailbox Store and Public Folder Store
- On the Mailbox Store and Public Folder Store properties, checked the "This database can be overwritten by a restore" box.
- Ran NTBackup to restore the database to a week ago. (Approx 1.5 gig, took about 5 min, seemed to be doing something)
The messages were not restored. I tried this several times. I sometimes get logon messages:
Unexpected error <<0xc1050000 - Unknown Error. The logon to the Microsoft Exchange Server computer failed. Microsoft Exchange Server
Just to check, I deleted a message in my inbox that has been there for about a month. I tried to restore from the backup I made a week ago, and from the temporary backup I made this morning. It did not restore.
I see a message that looks OK but I better mention it:
The information store database "First Storage Group\Public Folder Store (SVR02)" was restored from a backup - it has been patched. Please backup this database.
I actually see no evidense that the restore did anything. Any ideas what am I doing wrong?
