Exchange灾难恢复

从be还原邮箱数据库文件和日志后，在ecp直接挂载会提示无法挂载，然后使用esentutl命令进行修复，修复完成后，再将用户邮箱关联到该数据库即可。

创建恢复数据库：
New-MailboxDatabase -Recovery -Name RDB1 -Server 0-IDC-S-MAIL003

New-MailboxDatabase -Recovery -Name VIP-bak -Server 0-IDC-S-MAIL003 -EdbFilePath "D:\MailboxDB-Bak\Exchange Server\VIP-DB\File\VIP-DB.edb" -LogFolderPath "D:\MailboxDB-Bak\Exchange Server\VIP-DB\Logs"

#----State:Dirty Shutdownn
esentutl -mh "D:\MailboxDB-Bak\Exchange Server\VIP-DB\File\VIP-DB.edb"

#----Checkpoint：
esentutl -mk D:\MailboxDB\SYSMDB-DB\SYSMDB-DB.edb

#----r
Eseutil -r E03 /l "D:\MailboxDB\EMP-DB\logs" /d "D:\MailboxDB\EMP-DB\EMP-DB.edb"

#----State:Clean Shutdown
eseutil -mh "D:\MailboxDB\SYSMDB-DB\SYSMDB-db.edb"

#----p
Eseutil /p "D:\MailboxDB-Bak\Exchange Server\VIP-DB\File\VIP-DB.edb"

Restart-Service MSExchangeIS
Mount-database SYSMDB-bak



#获取所有用户邮箱信息，会提示找不到数据库
$usersall = Get-Mailbox #-Database emp-db
$usersall.count
$usersall |select samaccountname |sort samaccountname,displyaname |more

#从恢复数据库中查找用户邮箱名称
$bak = Get-MailboxStatistics -Database sysmdb-bak 
$bak.displayname
$bak.count
#批量设置用户邮箱到名为“vip-db”的数据库
foreach ($b in $bak[0..300])
    {
    if ($b.DisplayName -notlike "System*" -and $b.DisplayName -notlike "Health*" -and $b.DisplayName -notlike "就地存档*"  -and $b.DisplayName -notlike "ServiceManager*")
        {
        $b.DisplayName
        $usersall | ? {$_.DisplayName -eq $b.DisplayName}|set-mailbox -database "vip-db" -Confirm:$false -Force
        }
    
    }

(Get-Mailbox -Database vip-db).count


#恢复名为“zhangsan”的用户邮箱
$usersall | ? {$_.DisplayName -eq "zhangsan"}|set-mailbox -database "SYSMDB-DB" -Confirm:$false -Force
