According to KB318429, this could be a hardware issue.
As the hardware was on its last legs, there could have been corruption in the database
that was included in the backups you restored from.
Since you say that everything is perfect as far as viewing content is concerned, I
would move all of the mailboxes to PST files using EXMERGE and them restore them to a
new database. As a precaution, I would restore one or 2 PST files to the new
databases, push some smtp messages into the server to initialize the .stm file and
then retry the backup to see if the errors return. The .stm files hold all of the SMTP
based messages for the store so this file should not grow much with a restore of the
PST files. If you still get errors, you have a problem with the drive or the
controller.

Subject: HELP NEEDED - Problems with backup of exchange post restore
We have a single SBS2003 server with exchange 2003 on it.
We recently found out that the secondary disk (containing the exchange
database files) was on its last leg as well. We attempted to ghost this
disk to another new disk, but the ghost process suceeded in wasting 14
hours and accomplishing nothing.
Now the transaction logs and installation files for exchange are all on
the disk that is fine. Only the database files were lost. I followed the
below process to restore:
NTBackup to restore the Information store. This process completed, but the
IS would not start as it could not find the database files.
Stopped all exchange services.
NTBackup was then used to restore the EXCHSRVR folder containing the
databse files to the file system directly. The log files were not restored
from backup.
Started the exchange services
Event log entries of the log files replaying to the Information store were
seen, the storage groups mounted, and users could access the store.
There were no errors reported from any part of exchange that I could find.
Messages up to the point of the server being shut down were present and
everything seemed perfect.
However I then tried to run a backup of exchange, which I do by backing up
both the Information store and the exchsrvr folders. When the backup job
is doing the database files, ntbackup fails, and the following is logged
(a lot):
Event ID: 478
Source: ESE
Information Store (3120) The streaming page read from the file "F:\Program
Files\Exchsrvr\MDBDATA\priv1.stm" at offset 130048000 (0x0000000007c06000)
for 3866 (0x00000f1a) bytes failed verification due to a page checksum
mismatch. The expected checksum was 4236769710 (0xfc87f9ae) and the
actual checksum was 3214649499 (0xbf9ba89b). The read operation will fail
with error -613 (0xfffffd9b). If this condition persists then please
restore the database from a previous backup.
Can anyone suggest a way to get this problem resolved so we can backup the
exchange files?
Help is appreciated.
Regards,
Luke Cassar
