Administrator Guide

6. Use the ESEUTIL program to put the database into a clean shutdown. Use the following command,
run from the directory where the edb file exists: H:\Replay Users>eseutil /r e00 /1 "h:
\replay users" /s "h:\replay users" /d "h:\replay users"
7. In the Exchange Management Organization Configuration/Mailbox dialog box, right-click the
recovered database and select Mount Database.
8. Create a restore request for the mailbox to recover. For example, to restore an entire mailbox: H:
\Replay Users>new-mailboxrestorerequest -sourcedatabase emailrecovery1 -
sourcestoremailbox "John Hancock" -targetmailbox [e-mail]
where the target mailbox is the email address of the mailbox you are restoring.
NOTE: In the preceding example, the directory H:\Replay Users contains both the log and
database files. If the files are in different directories, use the /l /s and /d options to specify the
correct directories.
This restore command queues the request. As messages are restored, they will appear in the user’s
mailbox and can be accessed as soon as they are visible.Multiple restore requests can be queued,
and wild cards can be used to recover multiple mailboxes. The Exchange server processes all
requests until complete. This process can be used to recover everything from a single message to an
entire mailbox store.
NOTE: To recover from a corrupt database, create a blank database and use this procedure to
restore data to individual mailboxes. Database recovery is constrained only by server
performance, so messages will be restored as fast as the server can process them.

Replay Sizes and Storage Center Storage Profiles
By default, Storage Center is configured to use a 2 MB page size. The default page size works best for
most storage requirements. However, for some applications, such as Microsoft Exchange Servers, the
Storage Center defaults may result in larger than expected Replay sizes.
Customers who experience larger than expected Replays (for example, 75% or greater of database size)
can consider using the Storage Center 512 KB page option for Microsoft Exchange volumes on the
Storage Center. The smaller page size will reduce the amount of blocks that can write to a page, thus
reducing Replay sizes. For information on configuring and using a Storage Center Storage Profile with a
smaller page size, see the Storage Center System Manager Administrator’s Guide.
Microsoft Hyper-V
The Hyper-V extension included with the Replay Manager installation leverages the Hyper‑V VSS Writer to
provide enhanced backup and recovery of Hyper-V virtual machines. The Hyper-V VSS writer is capable
of taking snapshots both in an online and offline operation:
• Online backups use the Hyper-V VSS writer to perform the snapshot while the server is online and
does not cause an interruption in service.
• Offline backups (on Windows NT 4.0 or Windows 2000 guests) require that the machine be put into a
saved state while the snapshot takes place and does require a service outage.
NOTE: When using Replay Manager with Microsoft Hyper-V, only volumes hosting virtual hard
disk (VHD or VHDX) files are included in a snapshot. Virtual machine volumes are not included if
the volumes are mapped to a virtual machine by iSCSI or pass-through.
