I am in working on a restore process where I am restoring and Exchange 2007 mailbox that was backed up with GRT, and redirecting it to a new created mailbox on a newly created storage group/database. We created a new storage group as not to affect our existing storage group in case of a problem. It seems that was a wise decision.
We have been dealing with Symantec on another issue so we have update all remote agents to latest, as well as confirmed service account has all proper permissions to Exchange environment.
The problem...restore seems to be corrupting the database to some extent.
This is what has taken place...
- I created a new storage group/database (sgrestore)
- I created two new mailboxes (rstaug and rstjul) to redirect mailbox restore to. Mailboxes activated by sending and receiving.
- The restore process runs as expected, and job log show successful.
When acccessing the mailbox (rstaug) via OWA, it appears all is well, however when you go into the deleted items folder there is nothing to view, even thought the count says there is about 360 unread messages. All other folders seem fine as far as i can tell. Interesting when looking at count in status bar, it show a negative number (for example -2234234 of....)
This is when thing really start to go wrong...
I need to now restore a second mail with redirecting to a the other mailbox I created (rstjul). Restore goes as expected, but then seems to freeze.
The first mailbox (rstaug), is now no longer accessible.
Looking at event viewer on our mailbox sever there are a few database events:
Event Type: Error

Description:
MSExchangeIS (5068) sgrestore: The database page read from the file "P:\sgrestore\sgrestore.edb" at offset 1736704 (0x00000000001a8000) (database page 211 (0xD3)) for 8192 (0x00002000) bytes failed verification due to a page checksum mismatch. The expected checksum was 33495565194821632 (0x0077000a00fd0000) and the actual checksum was 907504490445 (0x000000d34b7b97cd). The read operation will fail with error -1018 (0xfffffc06). If this condition persists then please restore the database from a previous backup. This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem
The other entry I see:
