Recover Mailbox / Database (Exchange 2010)

All of you know that there are no storage groups in Exchange 2010 and hence no recovery storage groups as well. A recovery database (RDB) serves the functions carried out by a recovery storage group in previous versions of exchange. Few points need to be understood before we start playing with restore options in 2010.

- You cannot create a recovery database using the console. Use shell instead (New-MailboxDatabase -Recovery -Name RDB -Server “servername” -EdbFilePath "path" -LogFolderPath "path” )
- Recovery database can only be used for 2010 databases. Previous versions are not supported.
- You cannot create mailbox database copies of a recovery database.
- Online maintenance isn't performed on a recovery database.
- You cannot enable circular logging on RDB.
- A recovery database cannot be used to recover public folder data.
- Only one RDB can be mounted on a mailbox server at any time.
- Access to RDB using Outlook or OWA is not allowed.
- Mailbox management policies are not applied on a RDB.
- Mailboxes in a recovery database cannot be connected to user accounts.
- Data from a RDB can be merged to an existing mailbox or exported to a folder.

(1) After you restored Logs and Database file in to M:\

(2) Check your Database file's health (Clean Shutdown or Dirty Shutdown)

eseutil /mh "M:\Recover\E\Exchange_Snap_31102011-2300-20732\Database\Operation & Exploration\Operation & Exploration.edb"

(3) Also check Log files OK or Not
eseutil /ml 'M:\Recover\D\Exchange_Snap_31102011-2300-20732\logs\Operation & Exploration\e00'

(4) Soft Recovery without (/i or /a) options
eseutil /r e00 /l "M:\Recover\D\Exchange_Snap_31102011-2300-20732\logs\Operation & Exploration" /d "M:\Recover\E\Exchange_Snap_31102011-2300-20732\Database\Operation & Exploration"

(5) Repeat step 2 for database health, if it's clean shutdown

(6) You can start create new recovery database via EMS command
New-MailboxDatabase -Recovery -Name DB-recover -Server ny-mb1-1 -EdbFilePath "M:\Recover1\Operation & Exploration\Operation & Exploration.edb" -LogFolderPath "M:\Recover1\Operation & Exploration"

(7) After you've created the recovery database, mount it.
Mount-Database -Identity DB-recover

(8) Get-MailboxStatistics -Database DB-recover

(9) To recover the mailbox from recovery database to live database
restore-mailbox -identity zawhtet -RecoveryDatabase DB-recover

(10) Restore mailbox from recovery database to itsupport's mailbox specific folder
restore-mailbox -identity itsupport -RecoveryDatabase DB-recover -RecoveryMailbox zawhtet -TargetFolder "ZawHtet recovery"

(11) Restore Specific EMails to folder
Restore-Mailbox -identityinfo -RecoveryDatabase DB-recover -RecoveryMailbox zawhtet -SubjectKeywords "fuck off" -ContentKeywords "Bitches" -IncludeFolders \Inbox\Calendar -TargetFolder "Zawhtet's lost folders"

(12) Restore all the mailboxes from recovery database
Get-Mailbox -Database DB-recover | Restore-Mailbox -RecoveryDatabase DB-recover

(13) Remove recovery Database
Remove-MailboxDatabase -identity DB-recover


-------------------------------------------------------------------------------------
If the above steps doesn't work, you need to make hard repair.

eseutil /p "M:\Recover\E\Exchange_Snap_31102011-2300-20732\Database\Operation & Exploration\Operation & Exploration.edb"

After the process successfully completed, you can start defrag the database

eseutil /d "M:\Recover\E\Exchange_Snap_31102011-2300-20732\Database\Operation & Exploration\Operation & Exploration.edb"
